A 2018 Australian study tested 10 common cooking oils by heating them to 240 degrees Celsius over extended periods. Extra virgin olive oil produced the lowest quantity of harmful compounds of all oils tested — outperforming coconut oil, avocado oil and every seed oil including sunflower, which is the default cooking oil in most South African kitchens. The persistent myth that you cannot cook with extra virgin olive oil has been debunked by the Culinary Institute of America, the USDA and peer-reviewed research. EVOO is not just safe for cooking. It is the most stable option available.
Olive oil contains up to 300 times more squalene than any other vegetable oil — the same compound human skin produces naturally to stay moisturised and protected. A 2024 clinical trial published in Medicina found that olive oil polyphenols applied topically reduced wrinkles by 34 to 52 percent in 30 days. But there is a caveat: a University of Sheffield study found that topical olive oil can damage the skin barrier in some people, and its moderate comedogenic rating makes it unsuitable for oily or acne-prone skin. The emerging consensus is that eating high-quality cold pressed extra virgin olive oil may deliver better, safer skin benefits than applying it directly.
Cold pressed olive oil is extracted at temperatures below 27 degrees Celsius using mechanical force alone — no heat, no chemical solvents. This single constraint preserves over 90 percent of the antioxidants, polyphenols and volatile flavour compounds that make extra virgin olive oil valuable for both health and cooking. Heat extraction, by contrast, destroys up to 30 percent or more of these compounds and produces a bland, nutritionally diminished oil. At O for Olive, every bottle of extra virgin olive oil from Swartrivier Farm in Prince Albert is cold pressed within 24 hours of harvest to preserve the full spectrum of what the olives contain.
A Harvard study tracking more than 90,000 people over 28 years found that those who consumed olive oil daily had a 19 percent lower risk of dying from cardiovascular disease, a 17 percent lower risk of dying from cancer and a 29 percent lower risk of dying from neurodegenerative disease. The health benefits of olive oil and olives are no longer a matter of folk wisdom — they are among the most thoroughly researched findings in modern nutrition science.
A growing body of evidence suggests that South African extra virgin olive oil is not only fresher and more traceable than many imported alternatives — it may also be more likely to be genuine. With 26 percent of imported olive oils in South Africa failing quality tests for extra virgin classification, local producers are making a compelling case for buying homegrown.
Up to 70% of extra virgin olive oil sold in supermarkets worldwide fails to meet the quality standards printed on its own label, according to research conducted by the University of California, Davis — a finding that raises serious questions about what South African consumers are actually pouring over their food.
The problem is not limited to bargain-bin bottles. Studies published by the UC Davis Olive Center, along with investigations by consumer watchdog organisations in Europe and Australia, have found that mislabelling, adulteration and quality degradation affect products at every price point. For South African buyers, the issue is compounded by the distance that imported oil must travel and the time it spends in warehouses and on shelves before reaching a kitchen. Understanding how to identify real extra virgin olive oil is no longer a matter of connoisseurship — it is a matter of getting what you are paying for.
South African extra virgin olive oil has moved from regional curiosity to international contender in less than two decades. Local producers are now winning gold medals at the world’s most prestigious olive oil competitions, earning quality scores that place them alongside the best estates in Italy, Spain and Greece. For consumers who have long defaulted to imported Mediterranean oil, the evidence is becoming difficult to ignore: some of the finest olive oil in the world is now being pressed in South Africa.
Gold Medals and 97-Point Ratings: South Africa on the World Stage
The shift in perception has been driven by results. South African olive oil producers have collected gold and silver medals at competitions including EVOOEUM in Spain, the Mario Solinas Quality Award (run by the International Olive Council), the Los Angeles International Extra Virgin Olive Oil Competition and the London IOOC.
