OLIVE OIL PROCESSING
For businesses and serious growers considering olive oil extraction, the idea of owning a machine for under $10,000 may seem like an attractive entry point. However, achieving high-quality olive oil requires advanced extraction technology that meets food-grade standards. The extraction process is highly technical, demanding specialised equipment to maintain oil integrity and efficiency. This guide will help you understand the essential components of olive oil processing, the investment required, and the best options for entering the market.
Many low-cost machines marketed for oil extraction—often priced around $2,000—are screw presses designed for seed and nut oils. These do not meet the requirements for proper olive oil extraction. Producing premium extra virgin olive oil requires specialised machinery that includes:
Without these advanced components, it is impossible to produce high-quality olive oil that meets commercial standards.
Each of these stages demands industrial-grade technology, making low-cost extraction machines impractical for producing high-quality olive oil.
For those serious about maintaining full control over their production, the Frantoino Olive Oil Press is an excellent entry-level option. With a processing capacity of up to 50kg per hour, it delivers professional-quality results in a compact and efficient design. Owning your own machine ensures complete flexibility and control over your olive oil production.
f you’re looking for a cost-effective alternative, buying a used machine can provide savings while still allowing you to own your equipment. Though used machines can be harder to source, platforms such as Olive Machinery list available second-hand units.

OLIVE OIL PROCESSING SOLUTIONS
If you are looking for small-scale olive oil processing machines, olive oil processing machine prices, compact olive oil processing equipment for boutique groves, olive oil extraction machines for home use, olive oil press machines in Australia, the best home olive oil presses, and affordable olive oil processing machines for sale - many of which are available through The Olive Centre’s renowned range of processing, milling and extraction solutions.
Thinking about pressing your own olive oil for under $10,000 may seem tempting, especially for hobby growers. But when it comes to creating top-tier olive oil, a simple, budget-friendly machine won’t meet the needs. Producing quality oil requires carefully managed steps and solid equipment. Here's a clear look at how the process works and how beginners can get started without compromising quality.
Some machines, often sold for a few thousand dollars, claim to produce olive oil. But most of these are screw presses, which are more suited for seeds or nuts - not olives. For real olive oil extraction, you’ll need machinery built specifically to crush, knead, and separate the oil from the paste using centrifugal force. This setup ensures a high yield and preserves the oil’s natural flavour and antioxidants.
Getting into the actual steps means dealing with tough-skinned olives that need force to break down. From the initial crush to the slow and steady malaxing process, each part of extraction must be carefully controlled. Especially during malaxation, the paste needs to be stirred slowly and kept at the right temperature to let natural enzymes do their job and without this process the cell wall structure of the olive is not broken down to release the oil. This lets the oil separate cleanly during the separation phase of extraction. Machines under $10,000 typically lack the components and processes required to extract olive oil.
Olive oil extraction calls for power, control, and precision. Here's what’s involved:
If you're ready to begin, there are three practical routes depending on your budget and goals:
1. Buy Your Own Press - Frantoino Olive Oil Machine If you want full control and plan to press olives regularly, the Frantoino is a strong entry-level choice. It processes up to 50 kg per hour and gives you hands-on management of every step. You get compact, professional-grade results at home, making this machine perfect for small-scale producers who want flexibility and independence.
2. Consider Pre-Owned Equipment - Not everyone wants to invest in a brand-new setup right away. Buying a used press can cut costs without cutting quality - if you find the right machine. While second-hand units aren't always easy to locate, Olive Machinery has a section for used presses that may suit your needs. This option offers ownership without the higher initial spend.
3. Use a Nearby Processing Service - If you don’t want to buy a machine yet, look into local services that let you use commercial-grade equipment without owning it. This gives you access to professional tools without long-term costs. The Olive Centre’s processor map helps you find a service near you. This option is ideal for first-timers or those with smaller harvests.
Getting into olive oil production takes careful thought, but there are solid options for newcomers. Whether you want full control, a used machine that is cheaper on the budget, or access to a local press (see map-link below), there’s a solution that can work for your setup.
If control and consistency matter most, owning a machine like the Frantoino puts you in charge. If budget matters more, used equipment or shared services let you start small and grow. The key is to understand what each step requires and match that to the method that fits your goals.

For decades, engineers have envisioned a compact, efficient, and hygienic machine capable of producing extra virgin olive oil on-site. That dream is now a reality. Modern technology has made it possible for growers to produce their own extra virgin olive oil using a self-contained, economical system that delivers professional-grade results.
This innovation empowers Australian olive growers to add value to their produce - from picking and processing to bottling - using their own equipment. Beyond personal production, it opens the door for entrepreneurs to establish contract processing businesses, pressing olives for others with ease and precision.
Centrifugal extraction technology was a revolution in the olive oil industry. It replaced older, labour-intensive systems with continuous-flow designs that offered greater hygiene, improved labour efficiency, and higher capacity. These advances quickly made the traditional hydraulic press obsolete.
In the past, Mediterranean growers would haul heavy sacks of freshly picked olives - often already fermenting - to local mills. There, they would join the community in spreading the crushed paste onto mats and watching as hydraulic presses squeezed out the golden liquid. It was a scene rich with tradition, aroma, and anticipation.
Today, the romance of that process has given way to something far more refined. Continuous-flow extraction plants now accept fruit within 48 hours of harvest to prevent overheating and fermentation. Delivered in ventilated plastic crates, the olives enter stainless steel systems that maintain strict hygiene standards, emerging as pure, high-quality oil. The process may lack the old-world spectacle, but it ensures superior product consistency and safety.
Currently, hundreds of Australian processors are already achieving outstanding results with Oliomio systems, producing exquisite extra virgin olive oil from their own fruit. True to its name - Oliomio, meaning “My Oil” - this technology gives growers full control over every stage of production, from fruit to finished bottle.
Each Genuine Oliomio machine is backed by excellent technical support provided by The Olive Centre, the exclusive Australian distributor. The Olive Centre offers on-site installation and comprehensive after-sales care to ensure growers get the best possible results from their investment.
The rise of accessible, high-performance extraction equipment marks a turning point for the Australian olive industry. Growers can now operate with greater independence, reduce processing costs, and elevate the quality of their oil - all while maintaining the authenticity and freshness that consumers demand.
As The Olive Centre team notes, this innovation was made possible thanks to the enthusiasm and vision of Australian olive growers themselves. Their commitment to excellence has driven this exciting step forward in local production.
Whether you’re looking to press your own olives or launch a boutique processing service, Oliomio offers a practical, proven pathway to success. For more information and a free information booklet, contact The Olive Centre - and take the first step toward making “My Oil” truly your own.

Each Barigelli installation demonstrates efficient integration of key processing stages—crushing, malaxing, decanting, clarification, and control - within a single automated framework. The result is precise, continuous olive oil production tailored to modern operational standards. These installations reflect the reliability and scalability essential for both boutique and industrial olive oil processors.
Modern extra virgin olive oil (EVOO) production relies on continuous centrifugal extraction, which has largely replaced traditional presses. In a continuous system, olives are cleaned, crushed into paste, and then malaxed (gently mixed) before a horizontal decanter centrifuge separates oil from water and solids. This process is far more efficient and hygienic than the old press-and-mat method, which is now considered obsolete. Key quality factors include processing fruit quickly to avoid fermentation, maintaining low temperatures during malaxation, and minimising exposure to oxygen. For example, transporting olives in ventilated crates and crushing/milling within 24-48 hours of harvest helps prevent heat buildup and unwanted fermentation that could spoil flavour. Cleaning and de-leafing the fruit before crushing is also critical - removing leaves, dirt, and debris ensures no off-flavours or contaminants make it into the oil. Mordern mills typically incorporate washing and leaf-removal steps for this reason.
Temperature control is paramount during extraction. EVOO is generally produced under “cold-press” conditions, meaning malaxation is kept around ≤27 °C to preserve aromatic compounds and polyphenols. Longer malaxation times or higher temperatures can increase yield but will reduce polyphenol content and flavour freshness. Recent research confirms that malaxation time and temperature must be optimised per cultivar e.g., one study found that extending malaxation from 15 to 90 minutes caused polyphenols to drop by up to 70%. In Australian groves, where harvest season temperatures can be high, processors often monitor paste temperature closely and may use heat exchangers or vacuum conditions to control it. Shorter malaxation (20-40 minutes) at moderate temperatures is commonly employed to balance oil yield with quality retention. Equally important is timing from harvest - olives allowed to sit too long (especially in warm conditions) will start fermenting. Using shallow, well-ventilated bins and milling within a day of picking is recommended to keep olives cool and intact. Big Horn Olive Oil in USA, for instance, emphasises rapid processing: they cold-press olives within 2 hours of harvest to “lock in freshness and antioxidants,” drastically reducing oxidation time in between. Such practices help Australian producers achieve long shelf life (18 - 24 months) and vibrant flavour in their EVOO whereas Cockatoo Grove has a Midnight EVOO where they pick and press in the cool of the night.
Ongoing research in Australia has highlighted how harvest timing and orchard factors influence oil quality. As olives mature on the tree, oil yield rises, but phenolic compounds (antioxidants) tend to drop. In field trials across New South Wales and Victoria, early-harvest olives produced oils with higher polyphenol content and longer shelf stability, whereas late-picked fruit gave more mellow oils with lower antioxidant levels. Free fatty acidity and peroxide (rancidity indicators) remained low until fruit became overripe, but antioxidant-rich components like tocopherols and polyphenols decreased as the fruit matured, leading to reduced oxidative stability in late-season oils. Australian producers must therefore balance quantity vs quality: an early pick yields robust, pungent oils rich in healthful polyphenols, while a later pick yields more volume with milder taste. The table below (adapted from industry data) illustrates this trade-off:
| Harvest Time | Oil Yield (% by weight) | Flavor Profile | Antioxidant Level |
|---|---|---|---|
| Early (greener fruit) | ~12-16% (lower) | Green, grassy, intensely fruity; pronounced bitterness & pungency | High (rich in polyphenols) |
| Mid-Season | ~15-18% (moderate) | Balanced fruitiness; moderate pepperiness | Moderate |
| Late (ripe fruit) | ~20-28% (higher) | Mild, buttery, nutty; low bitterness/pungency | Lower (fewer polyphenols) |
Other local research has examined irrigation effects on oil quality. Water-stressed olive trees (common in Australian summers) often produce smaller, more bitter fruit with higher polyphenol content, whereas heavily irrigated trees yield plumper olives with diluted phenolics but higher total oil output. For example, a study found that deficit-irrigated trees had the highest polyphenol levels (and earlier fruit ripening) in dry years, while fully irrigated trees gave greater oil yields at the cost of some phenolic concentration. These findings underscore that post-harvest decisions (when to pick, how to handle fruit before milling/crushing) are just as crucial as the milling technology itself. Cutting-edge extraction equipment can maximise quality potential, but growers must still deliver quality olives to the mill and process them with urgency to produce premium Australian EVOO.
MORI-TEM offers a spectrum of Oliomio mills to suit different scales, from artisanal boutique producers up to small commercial cooperatives. All share the principles above, but with varying throughputs and degrees of automation. Below is an overview of the current Oliomio lineup and its characteristics:
To summarise the small-to-medium Oliomio models discussed above, the table below compares their capacities and key features:
| Oliomio Model | Throughput | Key Features | Typical Application |
|---|---|---|---|
| Spremoliva C30 | 30-40 kg/hour | Batch malaxer (discontinuous); basic mini-press setup; no built-in heating or automation | Hobbyists, micro-batch or lab use (older design) |
| Frantoino Bio | ~50-60 kg/hour | Continuous 2-phase system; single malaxer; simple controls; single-phase power; adjustable decanter nozzles | Boutique farms, artisanal producers, pilot plants |
| Oliomio 80 Plus | ~70-80 kg/hour | Continuous flow; horizontal malaxer with heating & temperature display; inverter speed control; basic CIP wash kit | Small farms (~0.5-1 ton/day harvest); estate olive groves |
| Oliomio Gold | ~90-100 kg/hour | Enhanced automation (auto malaxer & drum washing, variable-speed feed auger)waste pump included; single or 3-phase | Medium farms (~0.8 ton/day); premium boutique mills needing labour-saving features |
| Oliomio Profy 200 | ~150-200 kg/hour | Dual malaxers for semi-continuous processing; heavy-duty crusher; closed/vacuum malaxing; full automation; waste pump | Cooperative regional mills; small commercial processors (~1.5-2 ton/day) |
Table: Comparison of select Oliomio continuous mill models (MORI-TEM). All feature two-phase extraction, stainless steel construction, and integrated crushers and decanters; higher models add more automation and capacity. Note how the traditional press is absent - even the smallest Oliomio brings modern centrifugal extraction to the farm, highlighting the leap in technology from the old press or “monoblocco” mills of past decades.
For producers scaling beyond the monobloc units, MORI-TEM offers modular olive mill installations that handle larger throughputs while prioritising quality. These systems - marketed under names like Sintesi, Forma, Cultivar, and TecnoTEM Oliomio Sintesi Series - break the extraction process into separate machines (e.g., independent crusher, malaxer group(s), decanter, separator) designed to work in harmony. They introduce features like multiple malaxers for higher throughput, vacuum malaxation technology, and advanced control systems. Importantly, they still operate on the continuous two-phase principle and embody the same hygiene and automation ethos as the smaller Oliomio range. Here’s an overview of each series:
It is instructive to contrast the above Oliomio technologies with the outdated systems they have superseded - namely, the classic hydraulic press and early-generation farm mills (older “monoblocchi” units). Traditional olive presses involved grinding olives (often with stone mills) into paste, spreading that paste onto fibre mats, stacking them, and then applying tons of pressure in a press to squeeze out the oil/water mixture. This method, while romantic, had numerous drawbacks: it was labour-intensive and slow, exposed the olive paste to air for prolonged times, and was hard to keep clean. The mats and press equipment could harbour yeasts or moulds and were difficult to sanitise thoroughly. It was not uncommon for olives to begin fermenting in the interim between harvest and pressing - indeed, historical accounts describe farmers bringing sacks of olives to the mill that were “often already fermenting” by the time they were pressed. The result was oil of inconsistent quality and stability. Continuous centrifuge systems like Oliomio eliminated these problems by moving to an enclosed, stainless-steel process where olives are milled almost immediately after picking, drastically cutting the chance for fermentation or oxidation. The greater hygiene and speed of continuous extraction have improved average oil quality and made defects from processing (such as fusty or musty flavours from fermentation) much rarer in modern operations. As a report on introducing Oliomio technology in Australia noted, “centrifugal extraction…replaced older, labour-intensive systems with continuous-flow designs”, offering better hygiene, efficiency, and capacity - effectively rendering the old press method obsolete in quality-oriented production.
Early small-scale continuous mills (from the 1990s-2000s) were a huge step up from presses, but they lacked some refinements of today’s Oliomio models. For example, many older farm mills did not have automated temperature control for malaxation, nor continuous malaxer flow. The very first “Oliomio” monoblock (created by Tuscan innovator Giorgio Mori) was revolutionary for being compact and continuous, but subsequent generations have added further improvements. A comparison of features illustrates this evolution: the older Spremoliva 30 could only malax in batch mode (no simultaneous crushing while decanting) and had no heating system or temperature display on the malaxer. By contrast, an Oliomio 80 or Gold today has fully continuous malaxing with automated temperature control and readout. Earlier mills often used fixed-speed motors and one-size-fits-all settings, whereas new systems employ inverter drives and adjustable nozzles to accommodate different olive conditions (small, watery olives vs. large, fleshy ones, etc.). Another big leap is in automation: tasks like pomace removal and equipment washing, once manual, are now handled by integrated pumps and wash cycles in machines like the Gold and Profy. This not only reduces labour but also ensures more consistent cleanliness batch after batch. In terms of energy and water usage, modern two-phase decanters are also more sustainable - they eliminate the need for large volumes of dilution water required by traditional three-phase decanters (saving water and the energy to heat it) and produce a simpler waste stream (wet pomace) that can be repurposed or composted more easily than press liquor or black water from old systems.
Crucially, oil quality has improved with each technical advance. Traditional pressing often left higher sediment and water in the oil, necessitating longer settling or filtration and risking quicker oxidation. Continuous centrifugation yields cleaner oil immediately, and the lack of air contact preserves freshness. Chemical measures like peroxide value and UV stability are typically superior in oil produced by a modern continuous mill versus an old press, when starting with the same fruit. The ability to crush and extract within hours of harvest, at controlled temperatures, means free fatty acid levels stay extremely low and the positive flavour notes are maximised. Australian producers who have adopted the latest Oliomio systems consistently report better quality and consistency in their oils, even when processing smaller batches. As an example, Spring Gully Olives in Queensland upgraded to a two-phase Oliomio (150 kg/hr) and found it ideal: it allowed them to process their own crop and offer custom processing to neighbouring groves, all while producing oil that needed no further refining - “the 150 kg per hour Oliomio is an ideal capacity which allows small growers to have their own oil processed…and it leaves the oil in its natural state”. This kind of feedback underlines how modern machinery empowers even small-scale growers to achieve high extraction efficiency and premium quality that rivals the big producers.
In summary, the latest Mori-TEM Oliomio systems represent a convergence of advanced engineering and practical on-farm olive oil production. They enable professional, hygienic, and quality-focused extraction at scales from a few dozen kilograms up to several tonnes per hour. By carefully controlling each step - from fruit cleaning and crushing with minimal oxidation, to malaxation under controlled atmosphere, to efficient two-phase centrifuge separation - these machines ensure that the oil produced reflects the true potential of the olives. Australian growers using Oliomio equipment benefit not only from improved oil quality and shelf life, but also from greater independence and flexibility: they can harvest at optimal times and process immediately, rather than rushing to a distant community mill or risking fruit spoilage. The result is fresher, more flavorful extra virgin olive oil that meets the high standards of a sophisticated global market. And with the range of Oliomio models and configurations now available, producers can choose a setup tailored to their grove’s size and business model - whether it’s a one-person boutique press or a regional processing hub servicing multiple farms. The technology has truly opened a new chapter for the industry, one where tradition and innovation blend to produce the finest EVOO. Each bottle of oil pressed with these modern systems tells the story of careful harvest timing, immediate processing, and gentle extraction - a story that resonates strongly with Australia’s drive for quality and the world’s appreciation of premium extra virgin olive oil.
CONSUMER EDUCATION
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!
By contrast, other grades of olive oil are lower in quality or more processed:
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.
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)
A Roman-era olive oil press in Capernaum, Israel. Ancient presses used large millstones to crush olives, and the oil was separated by gravity. Today, modern cold-pressing uses centrifuge extractors, but the goal remains the same – to physically squeeze oil from olives without chemicals or high heat, preserving quality. (photograph of a Roman-era olive mill in Capernaum)
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.
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:
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!
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:
Drizzling extra virgin olive oil over a salad of avocado, tomato, and greens. Incorporating EVOO into daily meals can be as simple as using it to dress salads, dip bread, or finish cooked dishes – adding both flavor and healthy fats to the Australian diet.
Quick recipe ideas:
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:
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.
To round out our EVOO guide, here are some fun facts and bits of trivia that make olive oil even more fascinating:
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!

Best in Show!... what a close call!
Dr Richard Gawel in the nail biting lead up to the announcement had noted that the Best in Show has never been so close between 2 producers!
So in the Elite sport of EVOO tasting the triumphant winner with their single varietal of Piqual was Peter & Helen Wright from Grassy Spur Olives who have around 1500 trees and located in the Gippsland region of Victoria.
This season they had their olives processed by, ?multi-award winning oil producer, Andrew & Lyn Jamieson from Golden Creek Olives (who also was awarded with a Gold for their oil) all processed with their Oliomio machine! ?What a stellar effort and a label they can proudly wear as 'the Best Extra Virgin Olive Oil in Australia for 2013!'
Furthermore, other notable Gold awards in 2013 also processed with Oliomio machines are:
How vacuum olive oil processing came about? How has the olive oil extraction process changed in recent years?
"Extra Virgin olive oil is the art of those who produce it, the system helps the artist". - Giorgio Mori
We arrived at the year 2010 and realised that in recent years the method of production of extra virgin olive oil has changed a lot. ?Several years ago growers preferred to pick up the olives and store them in a warm room to dry them before processing; the system was not right as the instruments for oil extraction were not suited to process the olives in some other way.
Some years ago with the implementation of continuous extractors the waiting time before processing was considerably reduced; today everyone knows that the fruit has to be processed immediately after picking. ?We want to start from here, the fruit, which through a special system (3+ System) can give us an oil of unmistakable quality, not only chemical analysis but mainly organoleptic and healthy fresh oil being the result.
Why you should not leave anything to chance?
Human resources to implement such a system (3+system) are of primary importance. ?A skilled operator, which also must be the assessor, is careful and accurate in the cleaning of machines, this is required some days before olives are harvested you must verify the perfect functionality of the machinery and prepare the storage tanks for the new production. You should also check there are no strange odours in processing and storage rooms or within the machine itself.
The first day of work is dedicated to the cleaning of the machine using specific products such as citric acid, due to its anti-oxidative properties, to sanitise the plant completely. Once you have completed washed the machinery you begin processing with a small batch of say 300 kgs olives, this allows you to understand if the fruit is at the right degree of ripeness, naturally, the first processing will be called (LDF) reference process.
Assuming (LDF) is guaranteed to be effected in a period prior to the optimal collection time, you must be very careful to monitor the outdoor temperature which of course can be quite high > 20?C; this will bring risks of activating fruit fermentation, especially if the olives have a high sugar content. ?Throughout the working cycle, it will be necessary to quickly work with the mixing phase at low temperatures 22 - 25?C. The expert taster will taste the oil produced giving an evaluation mainly on the astringency, on the bitter intensity and on the balance of the product. Â On the basis of the results obtained it will be decided whether to start harvesting or wait a few days more.
Decisions taken, we start processing
Each company now has harvesting devices or machines that help to speed up the olive harvest, these equipment should also be equipped to intensely clean the product before processing so it is necessary to install a "Twig remover"? fitted to the fruit receival section of the machine, until a few years ago was not needed due to many hand harvesting operations switched over to mechanical harvesting. Together with olives branches and twigs arrive at the olive oil extraction plant a substantial amount of leaves which in many cases reaches 15% of the harvest. The olive must arrive at the washing section completely cleaned. Cleaning consists of two steps: washing and rinsing with clean water. Eventually, the olive must be dried before arriving in the crushing process.
You may wonder why and we say that lesser amount of water you add during process higher quality product you extract.
In conclusion, the olives harvested with machinery such as shakers, the fruit suffers much stress and must be processed within the day of harvest.
Point 1 of the (3 + System) Speed Crusher and variable air flow The characteristics of extra virgin olive oil are due to the DNA of cultivars plus those modified by the crushing system. ?During crushing, oxygen is needed in the right quantity to start oxidation actions. Especially in a fast crushing system, where the crusher impeller also serves as an aspirator, you have to control the influx of oxygen through the speed variation and constant filling of the crusher loading hopper. ?In the crushing phase, ?polyphenols are available, natural antioxidants which are important for the life of the oil, but above all for the level of health for the consumer (i.e. benefit) that fresh Extra Virgin Olive Oils offer. ?It seems impossible, but after crushing, polyphenols tend to degrade considerably and especially during extraction.
Where, as producers, we act to obtain a more harmonious product naturally from the cultivars in production. ?There are more instruments that can change the organoleptic aspect/character of the product, one above all is the crushing peripheral speed. ?Another always important factor is pre-crushing that in many cases are used during an advanced season to capture colour and intensity, then the grate holes that can be varied depending on the cultivar to control paste fineness.
At last remember, that crusher blades must be sharp and that the grid, if not rotating, must be equipped with external cleaner (by way of scraper) and over-heating minimisation channels; the olive should not heat more than 2?C compared to the inlet product temperature, since it would result in a bitter oil sometimes very unpleasant. ? The crusher in the system (3 + System) should never be mounted above the mixer.
Point 2 of the (3+System) Mixers with low oxidation impact
Unfortunately, mixing is a necessary process, that is why in our system we mix inside a closed tank and even with a slight depression (vacuum), in order to harness polyphenols levels, mixing times are reduced and temperatures are kept not higher than 25?C. ?The paste arrives into the mixer and once the mixing time passed it is directly transferred to the decanter for extraction. No more mixer to mixer transfer stage and loosing polyphenols on the way. The expert taster will be very important in advising the grinding time on the basis of the tasted product, analytically usually more you increase the grinding time more the polyphenols degrade.
Our system (3 + System) will only be equipped with enclosed malaxers.
Extraction, the Extra Virgin The paste arrives at decanter through a pump and enters inside the cylinder, the system acts to two outputs: one for the oil and the other for pomace and water (mixed together). At this stage, it is very important to avoid using a quantity of water higher than 5%. ?If you can work without water certainly the result will be even better (water leaches polyphenols). ?The first oil that comes out, as well as the last, must be put in a special tank containing "normal oil" not in the one containing "highest quality oil"?. ?During centrifugation, unfortunately, the polyphenols are lost. In our system to decrease this loss, there is saturation with an inert gas that cannot be used in all cases, there will be the expert taster to decide the use.
Point 3 of the (3+System) Quick Filtration Surely a decisive phase on oil quality is the (Quick Filtration). Considering the fact that our system is not equipped with a final separator, in order to remove vegetable residues and traces of dirty water, it is absolutely necessary to filter the oil immediately. Filtering at this stage will allow the oil to become + green but certainly, we treat the oil in such a way that we minimise the risk of oxidation or decay which usually occur after a few months to unfiltered oils. ?Remember that each time you move the oil with pumps or other; it suffers an oxygenation that is not healthy. From decanter to filter and then to final storage tank, these are the steps that the product must follow.
Olive Oil Storage, just as important as every other process The storage room must be air conditioned and the temperature shall move from 14-16? C. The tanks must be in stainless steel (not plastic) and saturated with inert gas or vacuum, the saturation procedure occurs through filling of gas in the tank, after the extra virgin oil is poured from lower side valve continuously and slow to avoid turbulence/aeration, the gas exits from the tank through the upper safety valve. ?Another important point: the product shall be bottled only a few days before being shipped, except in the case of stainless steel bottles where vacuum procedure is made before capping, for dark glass bottles, the passage of light is approximately 70%, then the oxidation risk is real.
Bottling Bottling extra virgin olive oil seems to be a simple operation without any difficulty, but you must be very careful to ensure that the oil goes into the bottle without creating turbulence/aeration and that before inserting the cap that all oxygen is removed that usually remains between the oil and the cap. By doing so the oxidative effect is considerably reduced. ?Finally, we remind you that if you want to avoid problems, extra virgin olive oil has to be bottled some days before delivery.
Conclusion and Recommendations
Each cultivar produces a different extra virgin olive oil, so different types of processing are required. ?The skill of the expert taster is important to get the best product; the system provides different solutions that can be interpreted in a unique way. ?An important factor that applies to all is that using our system (3 + System) you are sure to extract more polyphenols from the olives that range from 50 to over 100% compared to conventional processes. ?The water must be used only in extraction, if necessary, but always in low quantities. ?Lastly, one more important point is the cleaning of the machine which must be carried out daily and accurately in order to achieve the best product.
