This breakthrough technology represents the future of olive oil processing, with developments set to redefine efficiency and production performance. The Thermospeed system has demonstrated the capability to accelerate the olive oil extraction process by up to 50%, marking a significant advancement in processing speed and throughput.
At the core of the system is an innovative design that reduces malaxation time - the critical stage where the olive paste is gently mixed before separation. The Thermospeed achieves this by pumping the olive paste through a section surrounded by a temperature-controlled tube, which can either heat or cool the paste as needed. This process optimisation helps to enhance extraction efficiency while minimising oxidation, ultimately preserving the oil’s natural quality and nutritional value.
Early trials have shown no negative effects on olive oil quality, and research is continuing over the next 12 months to further evaluate and refine the system’s performance.
This remarkable innovation could soon be integrated into olive oil processing facilities worldwide, offering producers an efficient, sustainable, and scientifically proven step forward in extra-virgin olive oil production.
MARKET INSIGHT: GLOBAL OLIVE OIL ECONOMY 2023
Introduction
The global olive oil industry in 2023 has entered uncharted territory, experiencing an extraordinary surge in olive oil prices driven by a combination of climatic and economic forces. At the centre of this crisis lies Spain’s devastating drought, which has crippled the world’s largest olive oil producer. This severe shortage has led to a dramatic contraction in olive oil supply, triggering price escalation and a corresponding decline in consumer demand. The ripple effects are being felt worldwide, reshaping the balance between producers and consumers alike. Meanwhile, Australian olive oil producers find themselves in a rare position of advantage, benefitting from unprecedented market highs. This article explores the causes, consequences, historical trends, and economic signals surrounding this remarkable global olive oil price spike.
The ongoing drought across Spain stands as the principal factor behind the current olive oil price surge. As one of the largest olive oil-producing nations globally, Spain’s drastically reduced harvest - caused by months of extreme heat and minimal rainfall - has sharply curtailed olive oil availability in both European and international markets. This has intensified supply shortages, compelling consumers to pay more for what has long been a staple Mediterranean product. The interplay of limited supply and escalating demand has magnified price volatility, reinforcing the classic supply-and-demand imbalance now driving global markets.

As prices have risen steeply, the shortage of olive oil has led to a noticeable decline in consumption, particularly in Spain, where demand has reportedly dropped by around 35%. Consumers are now scaling back their purchases, finding olive oil increasingly unaffordable compared to other cooking oils. The once-steady household consumption patterns are shifting as people seek alternatives or modify their cooking habits. This contraction in domestic demand not only highlights the growing accessibility gap for consumers but also underscores the broader economic strain caused by high inflation and food price increases.
Amid the turmoil, Australian olive oil producers are experiencing a windfall. Thanks to limited global supply, Australian growers are commanding record prices exceeding AUD $8 per litre, marking the highest levels ever recorded in the nation’s olive oil industry. This lucrative period presents a rare opportunity for Australian exporters, with demand from Europe - including Spain itself - now turning toward Australian supplies. For producers Down Under, this unique reversal of roles underscores how regional climate resilience and diversified production can translate into significant financial gains when global shortages arise.
The olive oil market’s volatility is not a new phenomenon. Previous spikes occurred in 1996, 2006, and 2015, each triggered by weather-related supply constraints. Yet, the 2023 price explosion stands out as the most dramatic in recorded history -over 40% higher than any previous price peak, and roughly double the magnitude of earlier surges. This extreme escalation reflects not just climatic hardship but a clear pricing bubble forming within the market, echoing the cyclical nature of commodity pricing.
The olive oil sector has long followed cyclical pricing patterns, typically alternating between low and high price phases roughly every decade. The current surge aligns almost perfectly with the predicted start of another 10-year cycle, occurring just three years into its anticipated timeline. Furthermore, a notable correlation has been identified between the Australian Food Inflation Index and the Global Olive Oil Price Index as reported by the International Monetary Fund (IMF). This connection illustrates the deep interdependence between food commodity pricing and global economic conditions.
While the IMF’s benchmark prices are denominated in USD, for the purposes of this analysis they have been converted to AUD to track the trend relative to Australian markets. These benchmark indicators -based on the world’s largest olive oil exporters -serve as a reliable gauge of overall market direction, confirming how global shortages and inflationary pressures move in tandem.
Global olive oil prices show a recurring 10-year cycle, driven by droughts, crop shortages, and rising production costs
From a technical analysis perspective, the Relative Strength Indicator (RSI) is often used to measure price momentum and potential overextension in markets. On recent olive oil price charts, the RSI (represented in purple) indicates that prices have once again entered overbought territory - a level seen during previous speculative phases. Historically, such readings have preceded market corrections or reversals, suggesting that the current surge may not be sustainable in the long term.
Analysts caution that as the European olive harvest begins in September and October 2023, an influx of new oil supplies could help ease prices, though the timing and extent of this correction remain uncertain. Until then, speculative trading and limited inventory continue to support inflated market values.
The record-breaking olive oil prices of 2023, primarily triggered by Spain’s drought-induced production collapse, mark a turning point for the global olive oil economy. With consumer demand declining under the pressure of soaring prices and Australian producers thriving amid the scarcity, the industry is experiencing a dramatic rebalancing. Historical precedents, cyclical trends, and market indicators all point toward a complex, transitional period defined by volatility and uncertainty.
As the world’s producers, traders, and consumers adapt to these new market dynamics, one truth remains clear: olive oil - celebrated for its taste, health benefits, and cultural significance - continues to be at the mercy of both climate change and economic cycles. Stakeholders across the value chain must remain alert, flexible, and forward-thinking as the olive oil market navigates this extraordinary phase of transformation.

Esterification is a natural chemical reaction where free fatty acids (FFA) combine with alcohols, typically glycerol, to form esters. This process reduces the measurable acidity of the oil. While esterification can occur in the olive paste during milling, it is usually a minor contributor to quality changes compared with factors such as fruit condition, malaxation parameters, and extraction efficiency.
This diagram outlines the continuous olive oil extraction line: olives are crushed, malaxed, separated, clarified, and routed for bottling, while husk and wastewater are channelled to waste management systems.
When added to the paste, talc increases yield and improves malaxation and decanter performance.
Processing aids act physically or chemically on the olive paste. Some enhance enzyme activity, others alter pH or moisture, and a few influence esterification indirectly. Below is a breakdown of the main aids used by professional olive processors and how each relates to esterification.
Calcium carbonate is the processing aid most associated with apparent esterification effects.

Salt acts primarily on the physical structure of the paste rather than the oil chemistry.
Influence on esterification
Talc is inert and valued for its physical functionality.

These clay minerals are used more for paste modification or clarification.
Influence on esterification
| Processing Aid | Impact on Esterification | Notes |
|---|---|---|
| Calcium Carbonate | Moderate … via pH shift | Can lower measured FFA but may affect flavour and oxidation |
| Salt (NaCl) | None | Improvements come from better separation, not chemical change |
| Talc | None | Purely physical aid for difficult pastes |
| Enzymes | Minor, indirect | Mostly physical… chemical breakdown of cell walls |
| Kaolin | None | Improves rheology only |
| Bentonite | None | Used for clarification rather than extraction |

Esterification occurs when free fatty acids (FFA) in olives or olive paste react with natural alcohols—most commonly glycerol—to form esters. While this is a natural chemical reaction found in many biological systems, it usually plays only a small role during standard olive oil extraction. However, under certain processing or fruit-quality conditions, esterification can become more noticeable and can affect how acidity is interpreted during quality assessment.
Understanding when and why esterification occurs is important for mill operators, as it can influence extraction decisions, processing aid use, and the accuracy of acidity readings that determine Extra Virgin classification.
Esterification is not inherently harmful, but it becomes more noticeable when fruit quality is compromised or when additives alter the paste’s pH and reaction environment. This means that an oil’s reduced measurable acidity may not always reflect true quality improvement.
1. Higher Paste Temperatures
4. Extended Contact Time
5. Enzymatic Activity
When esterification occurs under the conditions described above, it can lower the measured FFA without actually improving the oil’s true chemical quality. This can mislead producers into thinking their processing steps or additives improved the oil, when in reality the acidity reduction was simply a chemical conversion—not a restoration of fruit integrity.
Producers who understand these mechanisms can:
In simple terms: Esterification becomes noticeable when the olive paste is warm, slightly alkaline, contains damaged fruit components, or sits too long before separation. Managing these factors helps prevent misleading acidity readings and supports genuine quality improvements.

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!
