What is a DOP Closure and how do you apply it to an Olive Oil glass bottle?  Once the olive oil has been filled into the bottle you can see the video on how to apply.

How to apply a DOP closure to an olive oil bottle

This video shows how a DOP closure can be applied to the olive oil bottle.  The non-refillable DOP snap closure once fitted is not removable.  The DOP is considered safe, hygienic and very easy to apply even without the need for machinery.  One pressure application can have the DOP applied to the bottle and is ready to remove the tamper-evident seal  and pour the olive oil directly from the bottle.

The non-refillable system is a new type that can be seen across Europe without the need for applying the thread to the bottle.

As Australia’s leading distributor for Sansone products, The Olive Centre provides expert advice, local support, and fast delivery — helping you choose the perfect stainless steel fusti to suit your needs

Preserving the integrity of high-quality foods and liquids - especially extra virgin olive oil (EVOO) - depends on two things: a sound understanding of correct storage parameters and the use of vessels engineered to uphold those conditions with absolute reliability. This is where Sansone, Italy’s premier stainless-steel tank manufacturer, stands far above conventional storage solutions. As global quality standards evolve, the industry has moved decisively away from breathable plastics & reactive metals. With increasing focus on purity, sustainability, and product shelf-life, food-grade stainless steel has become the internationally accepted gold standard for storing oils, beverages, ferments, honey, pharmaceuticals, and more. Within that space, Sansone’s range - distributed in Australia by The Olive Centre - has set the benchmark for durability, hygiene, and performance for over five decades.

Why Sansone Tanks Are the Ideal Match for Best-Practice Olive Oil Storage

International Olive Council (IOC) guidelines highlight the key threats to olive oil quality, i.e. oxygen, light, and heat, each of which accelerates oxidation and rancidity. Proper storage must therefore minimise air contact, prevent light exposure, and maintain stable, cool temperatures. 


Sansone’s engineering and material choices align perfectly with these requirements:

1. Oxygen Protection: Airtight Design & Minimised Headspace

The IOC highlights that once a container is opened, limiting headspace is essential to slow oxidation.

How Sansone supports this:

• Hermetic seals on lids, clips, and o-rings prevent oxygen ingress.
• Precision-machined threads on taps ensure no micro-air leaks.
  
• Many models come in incremental sizes, enabling producers and consumers to select volumes matching 1 - 3 months’ usage - the exact timeframe recommended by the IOC.
  
• Large containers allow for decanting into small stainless steel units, which the IOC recommends for preserving quality once larger cans are opened.
  

2. Light Protection: Stainless Steel as an Opaque Barrier

The IOC identifies light as the main threat to olive oil quality after oxygen.

Sansone’s advantage:

• Full stainless-steel construction completely blocks UV and visible light.
• Mirror-polished interiors resist residue buildup, ensuring no photoreactive particles remain on surfaces between batches.
  

3. Temperature Stability: Thermal Protection & Structural Integrity

The IOC recommends storing olive oil between 13 - 25°C, and notes that lower temperatures (even refrigeration) can slow oxidation.

Sansone excels in temperature resilience:

• High-grade AISI 304 (18/10) or AISI 316 steel (optional) maintains structural integrity regardless of ambient fluctuations.
• No warping, cracking, or polymer breakdown (common with plastic).
  
• Suitable for cold storage without material fatigue or risk of flavour contamination.
  

4. Hygiene & Safety: The Foundation of Sansone’s Philosophy

The IOC emphasises cleanliness, inert materials, and contamination avoidance.

Sansone tanks surpass these needs through:

• AISI 304 stainless steel for all food-contact surfaces; AISI 316 (optional) available where higher corrosion resistance is required (e.g., acidic ferments, saline solutions).
• Mirror-polished interiors prevent residue, microbial growth, or flavour carryover.
  
• Fully weld-sanitised or precision-seamed joins engineered for long-term purity.
  
• NSF-certified taps available on select models.
  

Whether storing EVOO, honey, wine, ferments, kombucha, tinctures, cosmetics, or nutraceutical extracts, Sansone containers guarantee an inert environment that preserves product integrity.

5. Durability & Long-Term Value: Sustainability Meets Performance

Stainless steel is durable, corrosion-resistant, and 100% recyclable - maintaining its quality through multiple recycling loops. Sansone’s robust construction means a single tank can last decades, dramatically reducing lifecycle costs compared with plastics or coated metals. Their longevity also prevents product loss due to leaks, contamination, or light-induced degradation, making Sansone an economically and environmentally superior investment for producers of all scales.

6. Functional Design That Enhances Workflow

Across the entire Sansone range - from 3 L benchtop units to 10,000 L industrial vats - each model is tailored for real-world handling:

• Ergonomic welded handles positioned for safe lifting.
• Optional wheeled frames for mobile production setups.
  
• Sight-glass compatibility for measuring levels without opening the tank.
  
• Clip-on lids for quick access in high-turnover operations.
  
• Reinforced bottoms for stacking stability and secure placement.
  
• Wide openings for easy filling and cleaning.

These design elements reduce labour time, improve occupational safety, and streamline production lines.

Extra virgin olive oil (EVOO) is extremely sensitive to light, oxygen, heat and metal contact. Packaging, therefore, plays a direct role in how long an olive oil remains “extra virgin.” Major reviews from UC Davis emphasise that optimal packaging must reduce light exposure, oxygen ingress, and headspace, while also ensuring cool storage. At the same time, producers—especially small to medium Australian growers—must consider costs, machinery requirements, recyclability, consumer preferences, and minimum order quantities (MOQ). Below is the most complete and updated comparison of all common packaging formats.

1. Plastic Bottles (PET)

Quality & Shelf Life

PET offers convenience and low cost but has moderate oxygen permeability and allows light penetration, which accelerates oxidation. A 2023 study showed PET-stored EVOO experienced higher acidity, peroxide values, UV oxidation indices and sensory degradation over 12 months—especially at elevated temperatures.

Chemical Safety

Migration of PET oligomers and antimony into oil is within regulatory limits, but increases under heat.

Sustainability

rPET has a lower carbon footprint than glass, but Australian recycling for PET varies by region.

Practicality

• Cheapest and compatible with basic filling lines.
• Lightweight and non-breakable.
  
• Perceived as lower-quality for premium EVOO.
  

Best for: High-turnover oils sold quickly and stored cool.

2. Metal Cans (Tinplate or Aluminium with Food-Grade Lining)

Quality & Shelf Life

Metal cans provide total light protection and excellent oxygen barrier characteristics. UC Davis stresses that lined cans effectively prevent metal migration and protect quality.

Compared with BIB, cans may show slightly faster oxidation when half-empty, but still protect oil well if stored cool. A 24-month study found both cans and BIB maintained EVOO within legal quality limits.

Consumer & Practical Benefits

• Easily filled by weight, needing no specialised equipment.
• Compatible with pull-up pourers that provide tamper evidence and reduce leakage.
  
• High consumer trust-no plastic contact with oil.
  
• Stackable and ideal for 3–20 L formats.
  

Sustainability

Steel and aluminium have high recycling rates in Australia.

Many producers prefer cans because Australian consumers are increasingly concerned about soft plastics, especially given the collapse of local soft-plastic recycling schemes (e.g., REDcycle).

Best for: Bulk, foodservice, premium oils, export, and producers who want reliability without specialised equipment.

3. Coloured Glass Bottles (Green / Amber)

Quality & Shelf Life

Glass is chemically inert. Coloured glass offers some UV and visible light protection—amber performs better than green - but clear glass accelerates photo-oxidation significantly.

Coloured glass slows degradation but still allows some light through, so shelf lighting and storage conditions matter.

Practicality

• Easy to fill.
• Caps can be hand-applied, or producers can install a screw-cap capping machine that forms the thread consistently, reducing leakage.
  
• Widely accepted for retail and gifting.
  

Sustainability

Highly recyclable, but heavy to transport. Bottle breakage is an inconvenience for producers.

Best for: Premium retail oils with attention to storage conditions.

4. Clear Glass Bottles

Research shows clear glass provides almost no light protection, leading to rapid losses in phenolics and faster oxidation.

UC Davis warns that clear glass should be avoided unless heavily covered by labels or cartons.

Best for: Fast-moving products or promotional oils kept strictly in the dark.

5. Bag-in-Box (BIB)

Quality & Shelf Life

Bag-in-box offers some of the best oxygen protection because the collapsing bag limits headspace oxygen, and the cardboard blocks light. Numerous studies, including 12- to 24-month trials, confirm superior preservation of phenolics, freshness, and sensory properties compared with bottles and cans.

Limitations for Australian Producers

• Requires costly specialised filling equipment (nitrogen flushing, precise tap sealing).
• High minimum order quantities for bags and taps.
  
• Soft plastics inside bags are not recyclable in most of Australia, causing consumer concern.
  

Consumer Perception

Plastic contact and disposal concerns hinder adoption, despite technical superiority.

Best for: Large producers with dedicated filling lines, subscription models, or export markets where BIB is accepted.

6. Bag-on-Valve (BOV) / Aerosol Pouch Systems

BOV packaging uses a hermetically sealed internal pouch separated from an external propellant. The oil never contacts the propellant; instead, it is dispensed by pressure.

Quality & Shelf Life

• Zero oxygen contact once sealed.
• Excellent light protection when used with opaque or metallic cans.
  
• Very low risk of oxidation compared with conventional bottles.
  

While formal olive oil-specific studies are limited, aerosol and BOV literature show extremely low oxygen ingress, making it ideal for sensitive oils.

Practical Benefits for Producers

• The Olive Centre can supply BOV systems, but minimum order quantities apply, increasing upfront cost.
• Allows controlled spray application, excellent for cooking oils, finishing oils, and portion control.
  
• Protects oil quality even after repeated use, unlike bottles that suck in air after each pour.
  

Consumer & Market Benefits

• Hygienic, non-drip, clean application.
• Perceived as modern and premium.
  

Limitations

• More expensive per unit than bottles or cans.
• Cannot be easily refilled or recycled as a single stream; consumers must dispose of the metal can + internal pouch.
  

Best for: High-end culinary oils, premium lines, foodservice, and producers wanting differentiation without investing in BIB equipment.

Practical Recommendations for Australian Producers

1. For maximum quality + minimal investment → Metal cans are the best balance: easy to fill by weight, compatible with tamper-evident pull-up pourers, highly recyclable, and very protective.
2. For premium bottled products → Use dark (preferably amber) glass, avoid clear glass unless fully shrouded, and invest in a thread-forming capping machine to prevent leaks.
   
3. For innovation and high-end markets → Bag-on-valve is an excellent oxygen-free system, ideal for dressings, premium oils, and portion control—MOQ applies, but no major filling-line overhaul is required.
   
4. For long shelf-life and export → Bag-in-box remains technically superior but is limited by consumer plastics concerns, poor soft-plastic recycling, and specialised filler cost.
   
5. For low-cost, high-turnover lines → PET can work if cool, dark storage is guaranteed. Not suitable for long-term premium EVOO.
   

Conclusion

Selecting the most suitable packaging for extra virgin olive oil hinges on finding the right balance between quality preservation, consumer expectations, and production practicality. Among all options, lined metal cans stand out as one of the most reliable and efficient choices: they are easy to fill by weight, offer excellent protection from light and oxygen, avoid consumer concerns around plastics, and are highly recyclable in Australia. Coloured glass bottles remain the strongest retail performer, pairing good product protection with strong shelf appeal and flexible filling options - from hand-applied caps to automated capping machines that minimise leakage risks. Clear glass should only be used for fast-moving products due to its poor light protection. 

 While innovative systems like bag-on-valve offer outstanding oxygen exclusion and controlled dispensing, their higher cost and MOQ requirements mean they are best suited for premium or specialised product lines. PET plastic bottles can work for value-oriented, short-shelf-life oils kept in cool, dark environments, but they are not ideal for long-term storage or premium markets. 

Overall, Australian producers benefit most by matching each packaging format to the oil’s intended shelf life, sales channel, and brand positioning. Thoughtful packaging selection not only safeguards quality but also streamlines production and aligns with evolving consumer and environmental expectations.

Valuing your olive oil processing machinery – from presses and decanters to tractors and harvesters – is an important task for Australian producers. Whether you’re a small boutique grove or a commercial olive operation, knowing what your equipment is worth helps with insurance, resale, and financial planning. This guide explains how to value used olive oil processing machinery (with notes on new equipment costs), covers multiple valuation methods, and offers a practical Australian context. We’ll also include example scenarios (like a decade-old olive press vs. a nearly new separator) and provide tips to maintain your gear’s value over time.  

Equipment in an Olive Oil Operation 

Olive oil production involves specialised machinery at harvest and processing time. Key processing equipment includes olive crushers or mills (to crush olives into paste), malaxers (which slowly mix the paste), and centrifugal decanters/separators (which separate oil from water and solids). Supporting items like pumps, olive washers, and filtration units are also part of the system. Many Australian groves also use standard farm equipment such as tractors, mechanical harvesters, pruning and spraying equipment, and irrigation systems. When assessing value, focus first on the core olive oil machinery, but remember that methods discussed here apply to your tractors, harvesters, and other farm gear as well.  

Modern olive processing machinery is a significant investment. For reference, a small continuous-flow olive mill (e.g. 30 kg/hour throughput) might cost around A$20,000 new, while a large commercial plant (capable of ~1 tonne/hour) can run into the hundreds of thousands of dollars. Such figures underscore why proper valuation is essential – these assets represent major capital on the farm. Below, we outline several methods to evaluate what these machines are worth, especially as they age or when considering second-hand purchases. 

Valuation Methods for Used Machinery 

Valuing used farm equipment is not an exact science – it’s often best to use multiple methods to triangulate a reasonable value. Common approaches include using depreciation schedules, comparing recent market sales, calculating value based on income or cost savings, considering insurance replacement cost, and accounting for residual (salvage) value. Each method gives a different perspective:

• Depreciation (Straight-Line or Declining Balance) – Calculates value loss over time based on age. 
• Market Comparison – Looks at actual sale prices for similar equipment in the current market.
  
• Income or ROI Approach – Values equipment by the income it generates or the savings it provides.
  
• Insurance Replacement Value – Considers what it would cost to replace the item new, minus depreciation.
  
• Residual/Salvage Value – Accounts for the minimal value at end-of-life (for scrap or parts).
  

Let’s break down each method in detail and how you can apply it.

Depreciation-Based Valuation (Straight-Line vs. Diminishing) 

Depreciation is the loss in value of equipment as it ages. A simple way to estimate a used machine’s value is to start from its original cost and subtract depreciation. There are two main depreciation methods: straight-line (also called prime cost) and declining-balance (diminishing value). Straight-line depreciation assumes the asset loses value evenly over its useful life, while declining-balance depreciation assumes a higher loss in early years and less in later years.

• Determine Useful Life: First, establish the expected useful life of the machine. The Australian Taxation Office (ATO) provides guidelines for many assets. For example, olive oil processing equipment has an effective life of about 15 years according to ATO determinations. (For comparison, general farm tractors are given about a 12-year effective life .) You can use these as a baseline, though actual lifespan can vary with usage and maintenance.
• Straight-Line Calculation: Under straight-line depreciation, each year the machine loses roughly an equal percentage of its original value. The ATO’s prime cost formula is: 
  

Annual Depreciation = Cost × (100% ÷ Effective Life). 

For instance, if a small olive press was purchased new for $30,000 and has a 15-year life, straight-line depreciation would be ~6.67% per year (100/15). After 10 years (two-thirds of its life), it would be about 10 × 6.67% ≈ 66.7% depreciated. In simple terms, its book value might be roughly 33% of the original cost (around $10,000 in this example). This assumes no residual value; in practice, you might add a small salvage value (see Residual Value section) instead of depreciating to zero. 

• Declining-Balance Calculation: Declining or diminishing value depreciation accelerates the write-down in early years. The ATO’s diminishing value method uses roughly 200% of the straight-line rate. For a 15-year life asset, this means ~13.33% depreciation per year on the reducing balance. Using the same $30,000 press example, the first year depreciation would be $4,000 (13.33%), leaving $26,000 value; the next year ~$3,466 (13.33% of 26k), and so on. After 10 years, the formula would yield a remaining value of only around 20–25% of the original (about $6,000–$7,500). This method better reflects how equipment often loses value fastest when it’s newest.

In practice, many farmers use straight-line for simplicity or for setting uniform annual book values, but diminishing value gives a more realistic market pattern (high initial depreciation, then levelling off). Keep in mind these calculations provide an approximate book value, not a guaranteed market price. Real-world prices can be higher or lower depending on demand and condition. Still, depreciation schedules are useful to set a baseline. In fact, for tax purposes, you may already have a depreciation schedule – for instance, if you claimed capital allowances using ATO rates, your asset’s tax written-down value is a starting point for its value. 

Example (Depreciation Method): You bought an olive mill for $100,000 new, which is now 10 years old. Using straight-line (15-year life), its book value would be roughly $100k × (5/15) = $33k remaining. Using diminishing value (13.33% yearly), its book value might be closer to $24k–$25k after 10 years. You could cite these as a range – perhaps saying the machine is “approximately $25k–$33k based on age” – then adjust up or down for condition. If your equipment’s been exceptionally well maintained or lightly used, it might fetch more than the book value; if it’s in rough shape, it could be less.

Market Comparison Approach

One of the most practical valuation methods is to see what the market is willing to pay for similar equipment. Check recent listings and sales of comparable olive oil machinery or farm equipment. In Australia, useful platforms include: 

• Online Marketplaces: Websites like FarmMachinerySales, Farm Tender, Gumtree, and even specialised sites (e.g. Used Olive Machinery on olivemachinery.com) list second-hand equipment. Use the search and filter functions to find gear similar to yours in make, model, age, and capacity. For example, on farmmachinerysales.com.au, you can filter by equipment type, brand, year, location, and even features, then sort by price to see the range of asking prices. This gives a ballpark of what sellers expect. Remember to note whether those are asking prices or finalised sale prices. 
• Specialised Dealers and Classifieds: The olive industry community often shares leads on used equipment. The Australian Olive Association or local grower groups might have classifieds. The Used Olive Machinery site mentioned above compiles listings – for instance, a listing for a used Oliomio 700 processing line with ~1,936 hours was recently posted, indicating the machine was well-maintained and had a decanter refurb at 1,500 hours. While that particular listing was marked sold with the price “POA” (price on application), details like hours give context. If you find a similar model on sale, you can gauge value by comparing usage hours and condition.
  
• Auction Results and Dealer Insights: Auction houses (like GraysOnline or farm clearing sales) sometimes sell olive equipment. Past auction results can signal what buyers paid. Additionally, don’t hesitate to talk to equipment dealers or valuers. Many farm machinery dealers have experience with resale values and can provide an informal appraisal or at least guidance on current market conditions. For niche machines, the dealer who sold it to you (or their competitors) might recall what similar used units went for.
  

Adjust for Differences: When using market comparisons, adjust for any differences between your machine and the listed ones. Key factors include age, capacity (throughput of a press in kg/hr), brand and model reputation, included accessories, recent overhauls, and location. For instance, if a press in WA is listed cheaper than one in VIC, consider freight costs or local demand differences. Also, recognise if the listings are scarce – olive presses are a niche item, so a lack of comparable sales might mean you rely more on general farm equipment trends or the other methods here. 

Example (Market Comparison): Suppose you own a 10-year-old press (same as above) and find two similar presses listed: one in NSW for $40k (fully serviced, ready for work) and one in SA for $30k (sold as-is, needs some repairs). If your machine is in good working order with maintenance records, the market approach might suggest a value in the high $30k’s. You’d then cross-check this against the $24k–$33k depreciation estimate – if the market seems to be paying a premium (perhaps due to a shortage of used presses), you might lean toward the upper end of the range. On the other hand, if no one is buying presses because many olive groves use custom processing services, you might have to price on the lower end to attract interest.

Income-Based (Cost Recovery or ROI) Approach 

Another angle is to value equipment based on the income it produces or the savings it provides. This method essentially asks: How much is this machine worth to my farm’s profitability? There are a couple of ways to think about it:

• Return on Investment (ROI): Calculate how quickly the machine “pays for itself” through additional revenue or cost savings. For example, owning an olive press means you don’t pay an outside mill to process your olives. If a custom processor charges, say, $300 per tonne, and you press 50 tonnes a year, that’s $15,000/year saved by having your own mill. If your press has 5 years of useful life remaining, it could “generate” roughly $75,000 in savings over that time. The present value of those savings (discounting future years) might be somewhat less, but it suggests the machine is quite valuable to your operation. In reality, you’d also factor in running costs and labour, but the ROI perspective might justify that paying, for instance, $40k for a used press is reasonable because you’d recoup that cost in under 3 seasons of savings.
• Income Stream Valuation: If the equipment directly produces income (e.g. you press oil and sell it, or you do contract pressing for other groves), you can estimate the net cash flow attributable to the machine. For instance, a separator (centrifuge) might enable higher oil yield or quality, boosting your product value by $X per year. You could then say the machine’s value is the net present value of those future cash flows. In practice, farmers often use simpler payback periods rather than complex discounted cash flow for on-farm decisions. A common rule is that machinery purchases should ideally pay back within their useful life or a set target (like 5-7 years). If a used harvester will save you hiring picking crews costing $20k/year, paying around $100k for it (5-year payback) might be justifiable, whereas a price of $200k (10-year payback) might be too steep unless the machine’s life is much longer. 
  
• Cost of Alternatives: Sometimes the value is inferred by what it would cost NOT to have the machine. For example, without a sprayer, you might lose yield to disease; without an on-site press, you might have quality loss or transportation costs. Those implicit costs can be hard to quantify, but are real. If a machine prevents a $50k loss one year (by enabling timely harvest or processing), that adds to its value for your operation.
  

Using an income-based approach can be especially useful for equipment that is still fairly new or for unique situations. However, be cautious: a machine’s value to you (because of your specific cost structure or needs) might exceed its open-market value. If you plan to keep using the asset, the ROI tells you its worth in your business. But if you plan to sell it, a buyer will be doing their own ROI calculation for their scenario. Use this method to inform your hold-vs-sell decisions and insurance needs (you want enough insurance to cover the loss of that income potential). If the ROI analysis shows a machine is barely breaking even for you, it might be a sign that its market value is also low (perhaps better sold and the capital used elsewhere). 

Example (Income Approach): Consider a recently purchased separator (centrifuge) that cost $15,000 new and is only 2 years old. Depreciation might put it at $10k–$12k book value now. But you bought it to improve your oil quality and yield – and indeed, oil yields went up 5%, earning you an extra $5,000 in oil sales each year. If we assume it has at least 8 years of life left, that’s potentially $40k additional income coming. Even discounting future years, the value-in-use of that separator might be on the order of $30k. Of course, no one would pay $30k for a used unit when a new one is $15k, but this tells you that for your own insurance, you might want it covered for replacement cost, and that selling it would only make sense if you exit the business or get a bigger unit. In other words, the ROI approach here tells you the separator is “worth more to me on the farm than to anyone buying it,” so you’d hold onto it unless necessary. 

Insurance Replacement Value

From an insurance perspective, valuation is about ensuring you could replace the equipment if it’s damaged or lost. There are two main concepts used by insurers:

• Replacement Cost (New for Old): This covers the full cost of buying a new equivalent machine at today’s prices. If you insure for replacement cost, you pay higher premiums, but if disaster strikes (fire, theft, etc.), the policy would pay out enough to purchase a brand-new replacement (provided you actually replace it). This is ideal for relatively new equipment or critical machinery you can’t operate without. Keep in mind the replacement cost might be higher than what you originally paid, due to inflation or newer models’ pricing. 
• Actual Cash Value (ACV): This is essentially replacement cost minus depreciation. In insurance claims, ACV is the replacement cost less wear-and-tear deductions. For older equipment, insurers often default to ACV. In practical terms, ACV = current market value. For example, if a harvester would cost $200k new but is 10 years old, an ACV policy might value it at say $80k (after depreciation), and that’s what you’d get if it were written off. The difference between ACV and replacement can be huge – one insurance guide notes that replacement coverage pays for a new item, whereas ACV coverage factors in depreciation and can result in tens of thousands less payout on older gear.
  

For valuation purposes, consider what number you’d put on an insurance schedule. Many producers annually review their policy and list each item with an insured value. If you have agreed value insurance, that figure might be the cap on your payout. Thus, setting it correctly is important: too low and you’re underinsured (and may be penalised by coinsurance clauses); too high and you’re overpaying on premiums for value you’ll never recover. Typically, you’d list either the current market value (if insuring ACV) or the replacement cost (if insuring for new). 

Where to find replacement costs? Contact dealers or check current price lists for the closest equivalent new model. For instance, if your 2008 olive mill is no longer sold, find the price of the current model with a similar capacity. Don’t forget to include freight to your location and installation costs in the replacement figure, as a new machine often involves these. In Australia, companies like The Olive Centre or Olive Agencies can provide quotes for new machinery. We saw earlier that small Oliomio units started around $19.5k a few years back – those prices can guide insurance values for hobby-scale equipment. For larger systems, get a formal quote if possible, since custom setups vary widely.

Also, consider partial loss scenarios: insurance may cover repairs. If you have an older machine, parts might be scarce, so even repairs could approach replacement cost. This is another reason some farmers insure older critical items for replacement cost if they can.

Tip: Document your equipment’s details (serial numbers, specs) and keep evidence of its condition. In an insurance assessment, having maintenance logs, photos, and appraisals can support your valuation. Insurers might depreciate based on a generic schedule, but if you can show your press was fully refurbished last year, you have a case for a higher value. As one farm insurer explains, typically anything over ~8–10 years might only get ACV coverage. If your gear is older but in mint condition or has an ongoing role generating income, discuss options with your insurer – you might opt for a higher agreed value or a policy rider for replacement.

Residual and Salvage Value Considerations

No matter which method you use, don’t forget that machinery usually has some residual value at the end of its useful life. This could be as spare parts, scrap metal, or a second life in a lower-intensity setting. Incorporating residual value prevents undervaluing the asset (and avoids over-depreciating on paper). 

• Salvage Value: This is the estimated amount you could get for the machine when you dispose of it after its useful life. For instance, large tractors might still fetch ~30–40% of their new price at 10 years old in decent condition, whereas very old, non-functional equipment might only fetch scrap steel prices. Setting a salvage value of, say, 10% of original cost is common in straight-line depreciation formulas, but it can be higher for well-built machinery. If your olive press is 20 years old and no longer suitable for prime production, you might still sell it to a hobby grower or for parts. Research scrap prices and second-hand parts demand: stainless steel components, motors, and gearboxes have value. Even if the entire machine is obsolete, a local metal recycler might pay per ton of steel.
• Residual Functional Value: Sometimes a machine is fully depreciated in accounting terms, but still works fine. In the olive world, older-style presses (the hydraulic press with mats, as used traditionally) may be inefficient, yet a small producer or an enthusiast might buy one for a few thousand dollars for the “romance” of old-school pressing. Don’t assume that reaching the end of the official life means the value is zero. There can be a floor price for any working equipment. Even if you yourself consider it beyond use, check around – you might find a buyer regionally or even overseas (export markets for used farm equipment can offer surprising opportunities). 

When valuing for sale, you might actually set your asking price near the salvage floor if the item is very old. This makes the offering attractive to bargain hunters while ensuring you recover at least scrap value. On the flip side, if you’re buying used equipment, be wary of prices that are at or below typical scrap value – it could indicate the machine is only good for parts. 

In summary, always account for the “leftover” value. For insurance, that might not matter (since a total loss is a total loss), but for appraisals and decisions like trading in vs. running to failure, knowing the salvage value helps. For example, if a decanter’s internals are shot, it might still have a salvage value of $5,000 for the stainless steel. That $5k is effectively the bottom-line value no matter what. 

Example (Residual Value): You have a 15-year-old tractor that’s been fully depreciated on your books. However, it still runs and could be a backup or sold to a small farm. Checking online, you see similar 80 HP tractors from the mid-2000s selling for around $15,000. That’s the residual market value. Even if you only get $10k due to some issues, that’s far above scrap metal value (maybe a few thousand). Therefore, in your valuation, you wouldn’t list the tractor as $0 – you’d acknowledge, say, a $12k residual value in fair condition. This logic applies to olive equipment too: an old olive washer or oil storage tank might be fully written off in accounts, but it has residual usefulness that someone will pay for.

Comparison of Valuation Methods

Each method has its strengths. The table below summarises and compares these approaches:

Example Valuation Scenarios

Let’s apply the above methods to two concrete scenarios to see how they complement each other:

Scenario 1: Valuing a 10-Year-Old Olive Oil Press 

Background: You purchased a medium-sized olive oil press (continuous centrifugal system) 10 years ago for $100,000. It has been used each harvest, processing around 50 tonnes of olives per year. It’s well-maintained, though out of warranty now. You are considering upgrading to a newer model and want to determine a fair sale price or insurance value. 

• Depreciation Estimate: With an effective life of 15 years, straight-line depreciation suggests about 2/3 of its life is used. If we assumed no salvage, book value ≈ $100k × (5/15) = $33,000. If we assume a salvage value (say 10% = $10k salvage), then the book value would be slightly higher (about $40k remaining depreciable portion – meaning roughly $40k if fully functional). The diminishing value method (13.33%/yr) would put it a bit lower, on the order of $25,000 remaining value. So from an accounting perspective, you’re looking at mid-five figures.
• Market Comparison: You search the classifieds and find one comparable press – an 8-year-old unit of similar capacity in another state listed for $50,000 (with extras like spare parts and a service history). There’s also a 12-year-old smaller press at $25,000. From talking to a dealer, you learn demand for used presses is moderate; many small growers prefer to use local contract processors rather than buy these outright. Given yours is 10 years and well-kept, you gauge that the market value might be around $30,000–$40,000 if you find the right buyer. You’d likely start by asking in the low 40s and be prepared to negotiate down to mid-30s. This aligns reasonably with the depreciation figures, perhaps a tad higher due to good condition. 
  
• Income/ROI: If you keep the press, how much is it worth to you? Pressing 50 tonnes/year at a custom rate of maybe $300/tonne would cost $15k/year, which you avoid by owning it. Over the next 5 years (assuming it remains operational), that’s $75k saved. In addition, having your own press has enabled immediate processing for quality (perhaps improving oil value) – but let’s focus on cost savings. The press “earns” $15k/year for you. If you sell it and switch to custom processing, you’d incur that cost. So internally, the machine is providing value. If you required a 5-year payback for a new purchase, $75k in savings suggests up to $75k could have been justifiable to pay for a press at this point. That doesn’t mean its market value is $75k (nobody will pay that since a new one is around that price), but it tells you that selling it for, say, $30k means the buyer is getting a great deal relative to what it could earn them. It may also inform your decision: if upgrading to a new $120k press, you’d compare the incremental benefits. The ROI view might actually convince you to keep the old press as backup or for capacity if its value-in-use is high and the resale market is soft.
  
• Replacement Cost (Insurance): A brand new equivalent model now might cost $120,000 (prices have risen). You have it insured for its replacement cost, which is smart for a vital machine under a replacement policy. However, if it’s under an ACV policy, the insurer would factor heavy depreciation – likely paying only around $30k if it were destroyed. You decide to check your insurance: perhaps you consider switching to replacement coverage if the premium is justifiable, because you know finding a good used replacement would be tough if yours failed. At minimum, you ensure the insured value reflects at least the mid-$30k range, so you’re not underinsured. You also keep documentation of the maintenance (e.g. you have service logs and receipts, which can boost perceived value to both buyers and insurers ). 
  
• Residual/Salvage: If the press utterly failed tomorrow (say the decanter drum cracked beyond repair), you could still sell it as parts – the motor, the stainless steel tanks, etc., might fetch a few thousand dollars. That sets a floor value of maybe $5k–$10k even as junk. This isn’t high, but it means you wouldn’t let it go for less than that under any circumstances. It also means in straight-line depreciation you might have set salvage = $10k, which matches the earlier book value calcs. 
  

Conclusion for Scenario 1: Taking all methods into account, you’d likely conclude the fair value of the 10-year-old press is around $35,000 (give or take). You might insure it for $120k (new replacement) if opting for that coverage, but you recognise market sale would be in the tens of thousands. If a potential buyer lowballs you at $20k, you know from multiple angles that’s likely below both its economic value and market trend – you’d counter higher, armed with knowledge that similar units list for more and that your machine can still generate significant savings. On the other hand, if someone offers $45k, you’d probably take it, acknowledging they are paying top dollar (maybe due to limited availability) above your depreciated value.

Scenario 2: Valuing a Nearly New Separator (Centrifuge)

Background: You bought a new centrifugal separator (vertical centrifuge for polishing oil) 1 year ago for $20,000. It’s a high-speed clarifier that improves oil quality. Unfortunately, you’re now restructuring your operations and might sell this unit. It’s in “as-new” condition. How to value it? 

• Depreciation: Effective life per ATO for such equipment might also be ~15 years (similar category as other processing assets). After 1 year, straight-line depreciation would deduct ~6.7% (~$1,333), so the book value is ~$18,667. Diminishing value at 13.33% would put it at ~$17,334 book. In other words, it hasn’t depreciated much – only 1 year old means maybe 85–95% of value remaining on paper.
• Market Comparison: The catch with very new used equipment is that buyers expect a discount vs. buying new (since they lose the benefit of being the first owner and possibly lose warranty coverage if it’s non-transferable). If new is $20k, a rule of thumb might be a 10–20% immediate drop once “used”. You check if any similar units are for sale – that’s unlikely given how new it is. Instead, you might call the supplier to see if they have demo units or trade-ins. Suppose they mention a demo separator was sold at 15% off the list price. That implies a fair market price of maybe $17k for a lightly used one. Considering yours has a full warranty remaining, you aim perhaps at $16k–$18k to entice a buyer (they save a bit, but you recoup most of your cost). Any more than that, and they may prefer to just buy new with full support.
  
• Income/ROI: In its brief use, let’s say the separator improved your oil enough to get a higher price, earning you an extra $3,000 in that year. If you were to keep it, the ROI is great – it’d pay for itself in under 7 years at that rate, maybe even faster if oil volumes grow. Selling it means you lose those benefits (unless you have an alternative). However, if you’re exiting olive oil production, the ROI to you going forward is moot – better to get cash now. If you weren’t existing, this scenario likely wouldn’t come up (you’d keep such a useful item). This highlights that ROI valuation is very context-dependent. For an ongoing producer, a machine that improves product quality could be “worth its weight in gold,” whereas for someone leaving the industry, it’s only worth what someone else will pay. 
  
• Replacement/Insurance: Being new, you probably insured it at the purchase price $20k (which is essentially replacement cost). It might even be under a year where the manufacturer or your business insurance covers it for full value. Any claim would likely get you a new one (less deductible). So insurance value is $20k. 
  
• Residual: The separator should have easily 10+ years of life left, so residual is far off. It might be worth perhaps $2k as scrap in a distant future. That’s not really relevant now except to note it holds value well through life. 
  

Conclusion for Scenario 2: For a nearly new piece, market pricing and buyer perception dominate. The depreciation method says it’s barely lost value, but real buyers will expect a “used discount.” A reasonable valuation might be around 80–90% of the new price (so roughly $16k–$18k). You would likely set an asking price near the high end (since it’s effectively new) and be willing to negotiate. If you can’t get at least, say, $15k, you might decide to keep it or bundle it with other equipment in a sale, because anything lower would be a big loss relative to its utility. These scenarios show how we use each method as a sanity check on the others. Depreciation gives structure, market gives reality, and ROI and replacement give perspective on value to the owner vs. buyer. In the end, the “right” value is often a range, not a single number, and it may hinge on finding the right buyer or having patience in the market.

Australian Market Factors in Machinery Valuation 

Valuing farm equipment in Australia comes with some local considerations that can affect prices and depreciation. Here are a few factors particularly relevant to Aussie olive producers:

• Regional Supply and Demand: Australia’s olive industry is modest in size and geographically spread (WA, SA, VIC, NSW all have groves). This means used olive equipment is a thin market. In areas like central Victoria or parts of NSW where olive growing is concentrated, there might be a few interested buyers for a used press, supporting your asking price. But in regions where olives are less common, demand is low – you might have to ship the item to a buyer elsewhere or accept a lower local price. Always consider the location factor: a machine in the remote Riverland or WA may sell for less than the same machine in central NSW, purely because fewer buyers nearby (and transport costs cut into what someone will pay). As one guide notes, prices can vary by location and demand – a factor to hone in on when comparing listings. 
• Climate Impacts (Drought and Bumper Seasons): Agriculture is cyclical. Prolonged droughts or poor harvests can force farmers to liquidate equipment, which can flood the market and depress prices. For example, if a drought severely cuts olive yields for a couple of years, some growers might decide to sell their processing gear, leading to more used presses on sale and thus lower prices to clear them. Conversely, after a few good seasons or an industry expansion (say new groves coming into production), demand for equipment can spike – used machines might fetch a premium because buyers want them immediately rather than waiting for new. Keep an eye on industry trends: if many groves are pulling out trees due to water scarcity, used equipment could be more abundant (buyer’s market). If olives are booming, used machinery might hold value strongly or even temporarily appreciate due to long lead times for new units.
  
• Distance to Service and Parts: Australia’s size means that service support for specialised machinery can be far away. Brand matters – a well-known brand with a local dealer or technician network (and readily available spare parts) will command a higher resale because buyers feel secure about keeping it running. For instance, an olive press made by a reputable Italian company with an Australian agent (like Mori-TEM’s Oliomio, represented by local agencies) is more desirable than an obscure brand with no local support. If you own the latter, expect to discount it, as the next owner takes on more risk (they might have to import parts themselves). Highlight any upgrades or commonality of parts in your machine if it helps – e.g. “uses standard ABB motors available locally” can ease concern. Additionally, if you’re in a remote area, a local buyer might factor in the inconvenience of servicing (e.g. “nearest qualified technician is 800 km away”). Sometimes the solution is to sell into a different region – e.g. a WA seller might find an east coast buyer if the machine is rare, but then transport cost must be negotiated. 
  
• Agricultural Incentives and Tax Environment: Australian tax policies can influence secondhand values. In recent years, schemes like instant asset write-off or temporary full expensing (especially during 2020–2023) encouraged new equipment purchases. This may lead to a surge of used equipment being sold when those new ones arrive (potentially softening used prices). On the other hand, if such incentives lapse, more people may seek second-hand to save money. Also, the ATO’s depreciation schedules (as discussed) create a common framework – many farmers will mentally value a machine around its written-down value for tax, since if they buy it, that’s what they can start depreciating from. Knowing that, a piece of gear fully written off by the seller might still have plenty of life – a buyer gets a tax advantage of starting depreciation anew (if they buy at a low price). This dynamic sometimes pushes low-hour used equipment to sell at high prices (almost new) because buyers can effectively depreciate it again themselves.
  
• Insurance and Finance Conditions: In Australia, if a piece of machinery is financed or used as loan collateral, the lender may require periodic valuation or adequate insurance. This can create a floor under prices because neither the bank nor the insured owner wants the declared value to fall below a threshold. Additionally, farm insurance policies here often use co-insurance clauses – you must insure for full value or face a penalty on claims. This means producers are incentivised to keep their insured values realistic. If everyone is insuring a certain type of tractor for $50k, that tends to also be roughly the market perception of its worth. 
  
• Seasonality: The timing within the year can affect sale prices. Right before harvest (late autumn for olives in Australia) is when demand for harvesters and presses peaks – a desperate buyer might pay more in April than they would in December after processing is done. If you’re selling, try to list just ahead of the peak usage season to catch buyers who realise they need equipment urgently. Conversely, if you’re buying and can wait until after harvest, you might find better deals from sellers who don’t want to store equipment over the off-season.
  

In summary, always put your valuation in context: the broader farm machinery market in Australia, olive industry-specific factors, and the local economic climate can all sway what someone is willing to pay. Stay informed through industry newsletters or networks (e.g. the Australian Olive Association news) to know if, say, a lot of groves are changing hands (could mean equipment up for grabs) or if new plantings are on the rise (potential buyers emerging).

Preparing for Insurance, Resale, or Tax Write-Downs 

Depending on your goal – insuring the asset, selling it, or accounting for it – you’ll approach valuation with a slightly different mindset and requirements. Here’s how to handle each:

• Insurance Assessments: When insuring farm equipment, decide between replacement cost vs. actual cash value coverage. For crucial olive equipment, many opt for replacement coverage if available, so that a total loss means you can buy new gear and continue operations. Work with your insurance agent to set the insured value. Provide any appraisals or evidence if the item is unique. For example, you might obtain a written valuation from a machinery valuer or dealer for your press – this can justify a higher insured value beyond book value, which is helpful if the insurer questions it. Also, maintain an inventory list with models, serial numbers, and your estimated value; update it annually. Insurance companies often require this detail, and having your own numbers (grounded in the methods above) helps ensure you’re adequately covered. Remember that at claim time, if you have ACV coverage, the payout will factor in depreciation. If your equipment is older, be financially prepared to cover the gap or consider an agreed value policy where you and the insurer pre-set a value. 
• Resale Preparation: If selling equipment, presentation and documentation can significantly influence the price. Before listing, service and clean the machine thoroughly – a well-presented item signals to buyers that it’s been cared for (and indeed likely fetches a better price ). Fix any minor issues if cost-effective; an intact, working unit attracts higher bids than one sold “as-is” with problems. Gather your maintenance logs, part replacement records, and the operator’s manual – these reassure buyers and give you an edge. As noted in a farm machinery sales guide, having a great service history with receipts can allay buyers’ fears and attract added interest. When pricing, use the valuation range you determined and perhaps list slightly above your mid-point (there’s usually some negotiation). Be realistic and honest in your advertisement description about age and condition – transparency builds trust, and you won’t waste time with the wrong buyers. Lastly, timing (as mentioned, selling before the season) and a wide advertising reach (listing on multiple platforms) will help you get the best outcome.
  
• Tax Write-Downs and Accounting: For your own accounting or when doing a tax write-down (disposal) of an asset, the value matters for calculating any gain or loss on sale. The ATO depreciation schedule gave you a book value; if you sell above that, there may be a balancing charge (essentially income) to declare; if below, a balancing deduction (a loss you can claim). It’s wise to align your valuation (and sale price) with fair market value to avoid red flags. Using the ATO’s effective life (e.g. 15 years for olive equipment ) ensures your depreciation is per guidelines, and any deviation in sale price is explainable by condition or demand. If you plan on scrapping the item, document its salvage proceeds (even if $0) – the ATO likes to see that you considered salvage. Also note, if you’re a small business using simplified depreciation (pooling assets), check the rules: assets under certain thresholds might be instantly written off, meaning their tax value is nil even if they have market value. That’s fine – just be aware that selling such a “written-off” asset still triggers income equal to the sale price. Consulting with your accountant on the planned value can ensure your financial statements reflect a sensible number. Many farmers keep an internal asset register with both tax book value and an estimated market value updated annually for management purposes – this is a good practice to adopt.
  

Maintaining and Enhancing Your Equipment’s Value

Regular maintenance, such as cleaning and servicing your machinery, is essential for preserving its value and performance. Proper care not only extends the working life of your equipment but also boosts its resale and appraisal value. Here are some practical tips for Australian olive producers to maintain asset value:

Specialised machinery like over-the-row olive harvesters can hold their value well if maintained, though hours of use and local demand are key factors. For instance, the Colossus harvester pictured (built in Mildura, VIC) had logged about 7,735 hours – yet with components rebuilt and good upkeep, it remains a sought-after asset for large groves. When valuing such equipment, consider service history (e.g. newly rebuilt conveyors or engines), as major refurbishments can extend useful life significantly. Heavy machinery also benefits from many of the tips above: regular cleaning (clearing out olive leaves and dust), timely engine servicing (as per John Deere engine schedules in this case), and storing under cover in off-season all help preserve value. Usage hours are akin to mileage on a car – they directly impact value, but how those hours were accumulated (easy flat terrain vs. rough use) also matters. Keeping detailed records (hours of use per season, any downtime issues resolved) will support a higher valuation when selling to the next operator. 

Finally, don’t underestimate the value of operational knowledge and support documents. If you’re handing off a complex piece of gear, providing training to the buyer or passing along your notes (like ideal settings for different olive varieties, or a log of any quirks in the machine and how to manage them) can make your item more attractive, thereby supporting your asking price. It’s not a tangible “value” in dollars, but it eases the sale and might tip a buyer to choose your machine over another. 

Conclusion and Valuation Checklist

Valuing olive oil processing machinery and farm equipment requires blending hard numbers with practical insight. By using depreciation formulas, checking market prices, considering the machine’s contribution to your farm, and factoring in replacement costs, you can arrive at a well-supported valuation range. Always adjust for the realities of the Australian market – our distances, climate, and industry size mean context is key. And remember, the way you care for and present your equipment can significantly sway its value.

Whether you’re insuring your olive press, selling a used tractor, or just updating your asset register for the accountant, a thoughtful valuation will pay off. It ensures you neither leave money on the table nor hold unrealistic expectations. Use the following checklist as a guide whenever you undertake a machinery valuation:

Valuation Checklist for Olive Machinery & Farm Equipment: 

1. Gather Equipment Info: Note make, model, year, and specifications. Find original purchase price if available. Record current hours of use or throughput processed. 
2. Assess Condition: Evaluate wear, any needed repairs, and overall condition (excellent, good, fair, poor). Consider maintenance history – compile your service logs and receipts. 
3. Depreciation Benchmark: Calculate age-based value using straight-line or diminishing value. (Use ATO effective life guidelines – e.g. 15 years for presses, 12 years for tractors – or your own expected life.) Note the resulting book value and remaining life. 
4. Market Research: Search online for similar equipment sales. Compare at least a few data points (listings or auction results) to gauge the current market value range. Adjust for differences (your machine’s extra attachments, or if your locale differs from the listing’s locale). 
5. Income Value Analysis: (If applicable) Calculate how much income or savings the machine provides yearly. Determine how many years of service remain and consider the present value of those benefits. This is more for your insight – e.g., if the machine saves you $10k/year and has 5 years left, that’s $50k of value to you. 
6. Replacement Cost Check: Get a quote or current price for a new equivalent. This is vital for insurance and also gives an upper cap (no one will pay more for used than new). Note if your machine has features no longer available in new models (sometimes older heavy-duty builds are valued by some). 
7. Residual Value: Estimate a reasonable salvage value. Even if rough – say 10% of the new price – it prevents underestimating value. If you already have buyers in mind (scrappers, parts dealers), even better to get a real figure. 
8. Local Factors: Account for any Aussie-specific factors: Is there strong demand in your region? Any upcoming industry changes (subsidies, big growers expanding or closing)? Also consider currency exchange if your machine is import-heavy – a weak AUD can make new imports costly, lifting used values. 
9. Set a Value Range: Synthesise the above into a range (e.g. “$30k–$38k”). You might choose a precise number within for different purposes (e.g. insure at replacement $50k, ask $38k for sale, keep $30k as lowest acceptable). 
10. Document and Explain: If presenting this valuation (to an insurer, buyer, or auditor), prepare a brief explanation. Cite the methods: “Based on age (10 years), the unit’s value is $X; comparable sales are around $Y; thus, we value it at $Z.” For insurance or formal appraisals, having this rationale written out (with sources if possible) adds credibility. 
11. Maintain for Future Value: If not selling now, implement the maintenance tips to protect this value. Update this analysis periodically (annually or after major changes). 

By following these steps, Australian olive producers can confidently put a number on their presses, harvesters, and tractors – a number grounded in reality. In turn, this helps in making informed decisions, be it negotiating a sale, choosing insurance cover, or investing in new equipment. Your machinery is the backbone of your olive enterprise; treating its valuation with the same care as you do its operation will ensure you reap the maximum reward when the time comes.

Valuing farm equipment is part art and part science. The science comes from formulas and data; the art comes from experience and understanding of how your machinery fits into the bigger picture. With the guidelines above, you have tools from both domains at your disposal. Happy valuing – and may your olive machinery serve you efficiently and profitably throughout its life!

Extra Virgin Olive Oil (EVOO) is often hailed as a “liquid gold” in kitchens around the world – a term famously used by the ancient Greek poet Homer. For Australians, EVOO is more than just an ingredient; it’s a heart-healthy cooking staple and a link to centuries of Mediterranean tradition. This guide will explain exactly what EVOO is and how it differs from other olive oils, how it’s produced (from grove to bottle), its science-backed health benefits, and the many ways you can use it – both in your cooking and beyond. Along the way, we’ll share some interesting facts that highlight why this oil has been prized since antiquity. Let’s dive in! 

What Is Extra Virgin Olive Oil (EVOO)?

Extra Virgin Olive Oil is the highest grade of olive oil, essentially the fresh “juice” of the olive fruit. It is obtained purely by mechanical means (crushing and pressing/centrifuging olives) without any chemicals or excessive heat. To qualify as EVOO, the oil must meet strict standards: free acidity of ≤0.8% (a measure of oleic acid) and no sensory defects in taste or aroma. In other words, a true EVOO tastes and smells fresh and pleasant (often fruity, grassy, or peppery) and is very low in free fatty acids. This minimal processing also means EVOO retains more of the natural antioxidants, vitamin E and plant phytosterols from the olives.

By contrast, other grades of olive oil are lower in quality or more processed: 

• Virgin Olive Oil (VOO): Also made by mechanical means with no chemicals, but comes from riper or lower-quality olives. It can have up to 2.0% acidity and slight taste defects, making it a lower grade than EVOO. Virgin olive oil is less common on supermarket shelves, as most high-quality production is sold as EVOO. 
• “Olive Oil” or “Pure/Light” Olive Oil: These commonly labelled supermarket oils are typically blends of refined olive oil and a bit of virgin oil. Refined olive oil starts as lampante (lamp oil) grade – oil from defective or over-ripe olives – which is then put through industrial refining (using methods like filtering, deodorising, high-heat treatment) to remove impurities and off-flavours. The result is a neutral-tasting oil with very low acidity, which is then mixed with a small amount of virgin olive oil to give it some olive flavour. These oils lack the rich flavour and many of the antioxidants of EVOO because refining strips away most polyphenols and nutrients. Note: Terms like “Pure,” “Light,” or “Extra Light” olive oil are marketing terms for refined oils – not lower-calorie oils. In fact, Australian standards don’t permit “Extra Light” on labels because it can mislead consumers; “light” just refers to lighter flavour, not less fat or calories.
  
• Olive-Pomace Oil: After the first pressing, the leftover olive pulp (pomace) still contains some oil. Lower-grade producers use solvents to extract this last bit, then refine it. The result, “olive pomace oil,” is an even more processed product used in some commercial frying or food manufacturing. It’s not allowed to be called olive oil under Australian standards, and it lacks the health attributes of EVOO.
  

In summary, EVOO stands apart from other olive oils because it’s unrefined, of top sensory quality, and packed with natural compounds. If you drizzle a good EVOO on a salad or taste it on a spoon, you’ll notice a bright, complex flavour – something you won’t get from the flat, one-note taste of refined “olive oil” blends. 

How Extra Virgin Olive Oil Is Produced 

EVOO’s journey from tree to bottle is a fascinating combination of ancient tradition and modern food science. It all starts in the olive groves. Olives destined for high-quality EVOO are often hand-picked or gently shaken off trees (modern farms may use mechanical harvesters that vibrate the trunks or use catching frames). The timing of harvest is crucial: early in the season, when olives are green to purplish, they yield less oil, but it’s very rich in flavour and antioxidants; later harvest (ripe black olives) yields more oil but with mellower taste. Many premium Australian producers, much like those in the Mediterranean, opt for early harvest to maximise quality.

Once picked, speed is key – olives are quickly transported to the mill, because freshly harvested olives start to oxidise and ferment if they sit too long. Ideally, olives are pressed within 24 hours of harvest to prevent quality loss. At the mill, the olives are washed to remove leaves and dust, then crushed (pits and all) by either traditional stone mills or modern steel crushers. This creates an olive paste, which is then gently malaxed (slowly churned) for 20–45 minutes. Malaxation allows tiny oil droplets to coalesce, but it’s done under strict temperature control – this is where the term “cold-pressed” or “cold extraction” comes in. To qualify as cold-pressed, no heat above 27 °C is applied during extraction. Keeping the paste cool preserves aromatic compounds and nutrients; higher temperatures could extract a bit more oil, but at the cost of flavour and antioxidants. Australian and European producers alike adhere to this, as heat can reduce EVOO’s polyphenols and vitamin E (and increase oxidation)

After malaxation, the paste is pressed or, more commonly, centrifuged. Modern mills use a decanter centrifuge, which rapidly spins the olive paste to separate oil from water and olive solids. The result is fresh olive oil (plus some vegetable water). The oil may then be filtered or simply left to settle so that tiny particles and moisture drop out over time. Some artisan oils are unfiltered, yielding a cloudy appearance, but most commercial EVOOs are filtered for clarity and stability. Finally, the oil is stored in stainless steel tanks (ideally with minimal air exposure) and later bottled. 

Throughout production, maintaining quality is paramount. At no point are solvents or refining used – EVOO is purely a natural juice. This careful process explains why EVOO is more expensive than generic cooking oil: it takes a lot of olives and care to produce. In fact, it typically takes around 4 to 6 kilograms of olives to cold-extract just 1 litre of EVOO (for some early harvest oils, even more). That represents roughly 8000–10,000 individual olives in each litre of premium oil! Such figures help us appreciate the effort and agricultural value inside each bottle of EVOO.

Australian EVOO note: Australia may be far from the Mediterranean, but it has a burgeoning olive oil industry of its own. Olives were first brought to Australia in the 1800s, and the industry remained small until a boom in the late 20th century. The Australian olive industry is over 150 years old, but it has expanded rapidly across all mainland states in recent decades. Today, Australia produces high-quality EVOOs, particularly in regions with Mediterranean-like climates (such as parts of South Australia, Victoria, and Western Australia). Aussie EVOOs often win awards for their robust flavours and purity, thanks to modern farming and milling techniques. So when you shop, know that some EVOO on the shelf – in addition to imports from Italy, Spain, Greece, etc. – is grown and pressed right here in Australia. 

Proven Health Benefits of EVOO 

Extra Virgin Olive Oil isn’t just a tasty fat – it’s exceptionally good for you. Its health benefits are backed by a wealth of scientific research and have even been recognised by international health authorities. Here are some of the top evidence-based benefits:

• Heart Health & Cholesterol: Replacing saturated fats (like butter or ghee) with EVOO can significantly improve your blood lipid profile. EVOO is high in monounsaturated fat (oleic acid), which is heart-friendly, but beyond that, it’s packed with bioactive compounds like polyphenols. Studies show that regular consumption of EVOO can lower LDL “bad” cholesterol levels while raising HDL “good” cholesterol. Even a relatively small daily intake (for example, 15–20 mL, about a tablespoon) has measurable benefits on cholesterol. The Australian Heart Foundation also recommends olive oil and other unsaturated fats as part of a heart-healthy diet, noting they can improve cholesterol levels and reduce blood pressure when used in place of saturated fats. In fact, populations adhering to a Mediterranean diet rich in EVOO have lower rates of heart disease. One long-term study found that people who used just half a tablespoon or more of olive oil daily had a 19% lower risk of heart disease death compared to those who ate little to none.
• Lower Blood Pressure: High blood pressure is a risk factor for cardiovascular disease, but EVOO may help keep it in check. Clinical trials have shown diets enriched with EVOO lead to significant reductions in both systolic and diastolic blood pressure over time. Polyphenols in EVOO are thought to improve blood vessel function (endothelial function), helping arteries relax and dilate, which lowers pressure. This blood-pressure-lowering effect is another reason EVOO-based diets (like the Mediterranean diet) are protective for the heart. 
  
• Anti-Inflammatory and Antioxidant Effects: Chronic inflammation is at the root of many diseases (heart disease, cancers, arthritis, etc.). EVOO has natural anti-inflammatory compounds. A famous example is oleocanthal, a polyphenol in fresh EVOO that actually mimics ibuprofen! Oleocanthal has a similar mechanism – it can inhibit COX enzymes, which are linked to inflammation and pain, and it’s responsible for the peppery “throat sting” high-quality EVOO often gives. (That little cough you might get from a robust EVOO is literally a sign of its potency; it’s the oleocanthal at work, and indeed it’s been likened to a small dose of anti-inflammatory medicine .) Additionally, EVOO’s plethora of polyphenols (like hydroxytyrosol, oleuropein, etc.) function as antioxidants, protecting your cells and blood lipids from oxidative stress. Research has shown that EVOO-rich diets reduce markers of inflammation in the body. For example, consuming EVOO can lower levels of inflammatory cytokines and oxidation of LDL cholesterol (oxidised LDL is particularly harmful for arteries). In simple terms, EVOO helps “cool down” inflammation and prevents oxidative damage internally, which is a big win for long-term health. 
  
• Diabetes and Metabolic Health: EVOO may improve blood sugar control and insulin sensitivity. It’s a key component of the Mediterranean diet, which has been shown to lower the risk of developing type 2 diabetes. For those with diabetes, adding EVOO can help reduce blood glucose spikes and improve HbA1c (a measure of long-term glucose control). One Australian study even found that incorporating EVOO in the diet significantly improved HbA1c levels in people with type 2 diabetes (from 7.1% to 6.8%) and was associated with a 55% relative risk reduction in developing diabetes in a high-risk group. 
  
• Other Potential Benefits: Research (mostly observational and some clinical) suggests EVOO consumption is linked with lower incidence of certain cancers, better cognitive function (potentially reducing risk of neurodegenerative diseases like Alzheimer’s), and even improved mood and lower depression rates. While these areas are still being studied, the general finding is that diets rich in EVOO correlate with longer life and lower risk of many chronic diseases. In fact, olive oil consumers in a large study had lower overall mortality (death from all causes) than non-consumers – an impressive testament to how protective EVOO can be as part of a healthy lifestyle.
  

It’s important to note that many of the benefits above are most pronounced with Extra Virgin (unrefined) olive oil, not the cheaper refined olive oils. The polyphenols and vitamin E that make EVOO so special are largely missing in “pure” or refined olive oils. For example, the U.S. FDA and European Food Safety Authority have acknowledged that consuming polyphenol-rich olive oil (at least 20 g providing ≥5 mg of polyphenols) can protect LDL cholesterol from oxidative damage – but you need genuine EVOO to get those polyphenols. 

Lastly, remember that EVOO is a fat and thus calorie-dense, so use it in place of other fats rather than simply adding on (to balance overall energy intake). But as fats go, EVOO is about the best you can choose for your health. It’s no surprise the Australian Dietary Guidelines and Heart Foundation include olive oil as a core part of a healthy eating pattern, encouraging people to swap butter and animal fats for olive or other plant oils. EVOO isn’t a miracle cure-all, but it is a potent, natural contributor to wellness – and a delicious one at that! 

Culinary Uses: Cooking, Dressing, and Beyond

One of the beauties of EVOO is its culinary versatility. You can use it raw, you can cook with it, you can even bake with it. Here are some popular ways to integrate EVOO into your daily diet, along with tips particularly suited for Australian kitchens: 

• Salad Dressings and Dips: Perhaps the simplest use – whisk EVOO with vinegar or lemon juice for a quick vinaigrette, or drizzle it straight on greens. A classic combo is EVOO with balsamic vinegar. In Australia, a popular appetiser is fresh, crusty bread dipped in EVOO with dukkah (a spiced nut/seed mix) – a delicious, healthy alternative to butter on bread. You can also drizzle EVOO atop dips like hummus or Greek yogurt tzatziki for extra richness.
• Cooking (Sautéing, Roasting, Frying): There is a persistent myth that you “can’t cook with extra virgin olive oil” – that it has a low smoke point or will burn. In reality, good EVOO has a moderate to high smoke point, around 190–210   °C (375–410   °F), which is sufficient for most stovetop cooking and oven baking. The average pan sauté is around 120– 150 °C, and deep-frying is ~180 °C, all within EVOO’s range. Extra virgin olive oil’s smoke point varies with quality (lower acidity oils have a higher smoke point), but many EVOOs won’t smoke until over 200 °C. More importantly, EVOO is very stable under heat due to its high antioxidant content and predominantly monounsaturated profile. Studies have shown EVOO to be one of the most stable oils for cooking, producing fewer harmful oxidation products compared to refined seed oils. So feel confident using it to sauté vegetables, stir-fry, pan-sear meats, or roast veggies. For example, toss your pumpkin, potatoes or sweet potatoes in olive oil and rosemary and roast them – they’ll come out golden and flavorful. (Tip: because EVOO is flavorful, its taste will be noticeable in baking; that’s lovely in an olive oil cake or when roasting tomatoes, but for delicate baked goods like scones, you might use a lighter-tasting refined olive oil or half butter/half EVOO.) 

• Grilling and Marinades: Olive oil is a key ingredient in marinades for meats, fish, or tofu. It helps carry flavours of herbs and spices, and also moistens/protects foods during grilling. Australian barbeques can get an EVOO upgrade: marinate your prawns or chicken in olive oil, garlic, lemon, and herbs before throwing them on the BBQ. Or brush veggies like eggplant and zucchini with EVOO so they grill without sticking and take on delicious char. A drizzle of fresh EVOO after grilling (on steak, fish or even pizza) can also boost flavour – this is called “finishing” a dish with olive oil. 

• Baking and Spreads: As Aussies look for healthier baking fats, EVOO is a great substitute for butter or margarine in many recipes. You can bake moist olive oil cakes (commonly lemon or orange-scented – a Mediterranean favourite), use EVOO in banana bread, or make pastry crusts with olive oil. Extra virgin oil will impart a slight olive fruit aroma to baked goods, which can be wonderful. Also try olive oil spread: simply mix EVOO with softened butter and a pinch of sea salt, then chill – it creates a creamy spread that has less saturated fat than butter alone. You can even drizzle EVOO on toast with Vegemite or avocado (many Aussies already enjoy avocado toast; adding a splash of good EVOO takes it to the next level of yum and nutrition).

• Soups and Pasta: In Mediterranean cooking, it’s common to finish soups or stews with a swirl of EVOO just before serving, to add richness and aroma. Try it with pumpkin soup or minestrone. For pasta, instead of heavy creamy sauces, a simple aglio e olio (garlic and olive oil) dressing is delicious – gently fry sliced garlic in EVOO, toss with spaghetti and chilli flakes. Or drizzle EVOO over cooked pasta and grilled vegetables. Basically, think of EVOO as both an ingredient and a condiment – a few drops on top of a dish right before eating can amplify flavour.

• Storing and Using: Keep your EVOO in a cool, dark place (pantry, not next to the stove) to maintain its quality, as light and heat can degrade it over time. Use it generously but also while it’s fresh – olive oil is best within 1–2 years of harvest (check bottle for harvest or best-by date). Rancid oil loses health benefits and tastes off, so it’s better to buy smaller bottles more frequently than a giant tin that sits for years. Fortunately, Australians are consuming more olive oil than ever – on average around 2 kg per person per year – so your bottle might not last too long anyway! 

Quick recipe ideas:

• Breakfast: Sauté mushrooms and spinach in EVOO and serve on wholegrain toast (instead of using butter). Or drizzle olive oil over smashed avocado and feta on toast, with a squeeze of lemon – a nutritious twist on avocado toast.
• Salad upgrade: Toss roasted beetroot and pumpkin with rocket (arugula), add walnuts and goat cheese, and dress with EVOO + balsamic vinegar. The olive oil helps absorb fat-soluble vitamins from the veggies and makes the salad more satisfying.
  
• Marinade: Mix EVOO with Aussie native herbs or lemon myrtle, add garlic and pepper, and marinate fish fillets for 30 minutes before grilling – a heart-healthy dinner. 
  
• Oven fries: Cut sweet potatoes into wedges, toss in EVOO, salt, pepper, and paprika. Bake until crispy. You’ll get tasty “chips” without deep frying, and the olive oil aids in browning and adds antioxidants. 
  
• Dessert: Try baking an orange and almond olive oil cake. The EVOO gives a moist crumb and a fruity aroma that pairs beautifully with citrus. Search for “Mediterranean olive oil cake” – you’ll find it’s a beloved recipe. 
  

In all these cases, EVOO isn’t just a passive oil – it actively enhances flavour. Its unique taste can range from buttery to grassy to peppery, depending on the olive variety and harvest. Explore Australian-produced EVOOs too; some are made from single olive cultivars (like Picual or Frantoio) and have distinct tasting notes. Much like wine tasting, you can even do olive oil tastings to appreciate the differences (yes, olive oil sommeliers are a thing!).

Beyond the Kitchen: Non-Culinary Uses for Olive Oil 

Olive oil’s usefulness goes far beyond food. Throughout history, olive oil has been used in daily life in myriad ways – and many of these uses are still relevant or just plain handy today. Here are some nonculinary applications of olive oil: 

• Skin Moisturiser and Cleanser: Olive oil can work wonders as a natural beauty product. It’s a common ingredient in soaps, lotions, and DIY skincare. You can use a few drops of EVOO as a moisturiser for dry skin or hands, rub it into dry cuticles to nourish nails, or even apply it to chapped lips instead of lip balm. Olive oil is rich in vitamin E and antioxidants, which may help soothe inflammation. (Tip: For a simple exfoliating body scrub, combine olive oil with sugar – it will leave your skin soft .) In fact, the famous Castile soap from Spain is traditionally made from olive oil. Many artisan soap makers and natural cosmetic brands still prize olive oil for its gentle, hypoallergenic properties.

• Hair Care: If you have dry or frizzy hair, olive oil can come to the rescue. Warm a few tablespoons and use it as a deep conditioning mask – massage into your scalp and hair, leave for 15-30 minutes (you can cover with a shower cap), then shampoo out. It helps add shine and reduce split ends. Just a drop rubbed between your palms can also tame frizz and protect hair ends from damage. Some people also swear by olive oil to treat dandruff or dry scalp, as it has a soothing effect. 

• Makeup Remover: Olive oil can gently dissolve makeup, including stubborn mascara or theatre makeup. Apply a small amount to a cotton ball and wipe – it will remove makeup while moisturising your skin. Afterwards, wash your face with a normal cleanser to remove the oily residue. This is an inexpensive, natural alternative to commercial makeup removers (just avoid getting it directly in your eyes). 

• Shaving and Personal Care: Out of shaving cream? Olive oil can act as a shaving lubricant – smooth a thin layer on your skin and shave as usual. It reduces razor burn and leaves skin hydrated. It’s also sometimes used as a massage oil base; mix a bit of olive oil with a few drops of an essential oil (like lavender or peppermint), and you have a lovely massage oil with aromatherapy benefits.

• Household Uses: Olive oil’s utility extends to the home as well. Have a squeaky door hinge? A tiny drop of olive oil can lubricate it. Need to condition a wooden cutting board or wooden utensils? Food-grade oils like olive oil can be used to season wood (though mineral oil is more commonly recommended since it doesn’t go rancid as quickly). For a quick fix on dried-out wood furniture, you can mix olive oil with a bit of lemon juice and use it as a natural furniture polish – it can restore lustre to wood surfaces. Olive oil can also help remove sticky label glue. Or get gum out of hair by dissolving the stickiness – just be sure to wash the area with soap afterwards.

• Lamps and Candles: Going truly old-school, olive oil was the lamp fuel of the ancient world. In a pinch, you can actually burn olive oil in certain oil lamps as it’s relatively stable and has a high flash point. Olive oil candles (usually a wick in a container of olive oil) are a DIY project some people use for a cozy, slow-burning light source that doesn’t emit the chemicals that petroleum-based candles might. Fun fact: ancient Mediterranean peoples, including Egyptians and Romans, routinely used olive oil lamps for lighting – it was considered a clean and precious fuel.

• Historical self-care: The concept of using olive oil for skin and body care isn’t new. The Ancient Greeks and Romans used olive oil like a soap – they would smear it on their bodies and then scrape it off with a strigil (a blunt metal scraper), effectively removing dirt and dead skin. They found that it both cleansed and moisturised the skin. Olive oil was also infused with herbs or perfumes for use as a body oil or hair tonic in many cultures.

As you can see, a bottle of olive oil in the cupboard can double as a mini home remedy kit! One caveat: for non-food uses, you don’t necessarily need to use your finest extra virgin oil – a basic grade or older bottle that you don’t want to cook with can find a second life polishing your coffee table or deep-conditioning your hair. Food-grade olive oil for beauty and home use means you’re avoiding the petrochemicals found in some commercial products, which is a win for those with sensitive skin or who prefer eco-friendly options. 

Interesting Facts and Trivia About Olive Oil 

To round out our EVOO guide, here are some fun facts and bits of trivia that make olive oil even more fascinating:

• Ancient Prestige: Olive oil has been treasured since antiquity. Besides being “liquid gold” to Homer, it was so valued that in ancient Olympic Games, winners were crowned with olive wreaths, and often awarded amphorae (jars) of top-grade olive oil – a highly prized reward. (In the 2004 Athens Olympic Games, organisers even used branches from a 2,000+ year-old olive tree in Crete to make victor’s wreaths, connecting modern athletes with ancient tradition !)
• Etymology: The very word “oil” has its roots in olive oil. It comes from Latin oleum, which in turn came from the Greek elaion, meaning olive oil. That’s because for Greeks and Romans, “oil” by default meant olive oil – it was the primary oil they knew. Many Romance languages still reflect this (e.g., olio in Italian means oil, implicitly olive oil). The word “olive” itself traces back to Greek elaia. So when you say “oil,” you’re linguistically invoking olives! 
  
• Olive Trees Live for Millennia: Olive trees are amazingly long-lived. They grow gnarled and hollow with age but can survive for many centuries and continue to bear fruit. One famous example is the Olive Tree of Vouves in Crete, Greece, which is estimated to be at least 2,000 years old – and possibly over 3,000 or 4,000 years old, according to some scientists. Incredibly, that tree is still producing olives today! Throughout the Mediterranean, there are numerous “millennial” olive trees. In Croatia, Spain, Italy, and the Middle East, you can encounter trees that were planted around the time of the Roman Empire or even earlier. Talk about resilience! (However, note that exact dating is tough; some recent studies suggest many aren’t quite as old as legend says, but certainly hundreds of years old at least.) Regardless, olive trees symbolise peace and longevity – qualities embodied in their oil as well. 
  
• “The Great Healer”: The ancient physician Hippocrates, often called the father of medicine, referred to olive oil as “the great healer.” He prescribed it for various ailments – from soothing skin conditions to helping with pain. Modern science, as we saw in the health section, echoes some of these beliefs in different terms (anti-inflammatory, cardioprotective, etc.). It’s fascinating that over 2,000 years ago, olive oil was recognised for its therapeutic properties. 
• Olive Oil as Currency: In certain eras, olive oil was so valuable that it functioned like currency. It was a major trade commodity in the ancient world. For instance, in medieval Spain under Islamic rule, taxes were sometimes paid in olive oil because it was considered liquid wealth. The storied prosperity of ancient civilisations like the Minoans and Phoenicians was partly built on the olive oil trade. There’s even a story of the Greek philosopher Thales using knowledge of an upcoming good olive harvest to rent all local olive presses in advance; when the bumper crop came, he made a fortune – essentially an olive oil futures market in the sixth century BC! 
• Only Cooking Oil from a Fruit: Unlike seed oils (canola, sunflower, etc.), which are extracted from hard seeds often using industrial processes, olive oil is unique in that olives are fruits, and EVOO is a fresh-squeezed fruit juice. It requires simply crushing and separating the natural oil. This is why high-quality EVOO is cloudy when unfiltered and has distinct taste nuances, much like a fruit juice. It also explains why it perishes with time (it’s best when young and fresh). 
• Smoke Point Misconception: We touched on cooking with EVOO, but it’s an interesting fact on its own: Many people assume you cannot fry in olive oil. In reality, Mediterranean cultures have fried in olive oil for generations (think Spanish churros, Italian fritto misto, etc.), and studies by food scientists have confirmed EVOO’s stability makes it ideal for frying – it resists oxidation better than many refined oils. So the humble fish & chips could be made a tad healthier if fried in olive oil (some fish and chip shops in Australia have started doing this to differentiate their product and because the oil lasts longer in the fryer without breaking down). 
• Colour is Not a Quality Indicator: Olive oils can range from deep green to golden to pale straw colour. Don’t judge an oil by its colour alone. Some excellent EVOOs are green (often those made from early harvest or certain olive varieties with high chlorophyll), while others are yellow. The flavour, aroma, and chemistry determine quality, not the hue. In fact, professional olive oil tastings use blue or brown tasting glasses so the evaluator can’t see the colour and be biased. So, that old trick of picking the greenest oil isn’t reliable – better to look for quality certifications or awards on labels, or just taste it. 
• Sediment or Cloudiness: If you see some sediment at the bottom of a bottle of EVOO, it’s likely unfiltered, and those are tiny bits of olive flesh – it’s not a defect per se. In unfiltered oils (also called “olive oil veiled”), the microscopic solids can add extra flavour, though they also shorten shelf life a bit. Most large producers filter oil for stability and appearance, but artisan oils might not be filtered. If you store olive oil in a cool spot, it might even solidify or get cloudy (especially in the fridge), because it contains waxes – this will clear up at room temperature and is not a sign of it being spoiled. 
  

With these facts, it’s clear that EVOO is not just another cooking oil – it’s a product steeped in history, cultural significance, and nutritional science. Few ingredients check as many boxes: flavour, health tradition, and versatility. It’s no wonder Mediterranean people historically treated olive oil with reverence, and why modern nutritionists sing its praises.

Conclusion

Extra Virgin Olive Oil is truly a kitchen all-star – it elevates our food and supports our health. We’ve learned that EVOO differs from lesser olive oils in quality and production, coming straight from fresh olives without chemicals or refining. We’ve seen how it’s made, preserving its sensory and nutritional treasures. Science shows that incorporating EVOO into your diet can benefit your heart, reduce inflammation, and even help you enjoy your veggies more (because they taste better with a good drizzle!). And beyond cooking, olive oil proves its worth in our beauty routines and households. 

For Australian consumers, the message is embrace EVOO: use it in your salad dressings, swap it for butter when you can, try it in new recipes – both traditional Mediterranean dishes and local Aussie favourites. With Australian olive oil production on the rise, you might even explore home-grown EVOOs, which can be world-class. Remember to store it well, use it generously but mindfully, and appreciate the story behind it – from ancient olive groves to your dinner table. 

In summary, Extra Virgin Olive Oil is more than an ingredient; it’s a lifestyle choice towards better eating and living. So go ahead – enjoy that splash of liquid gold in your meals every day, and taste the difference it makes!
