A bottle of extra virgin olive oil, the gold standard among vegetable oils, cold-extracted from selected olives.

About this subject

Extra virgin olive oil is the highest and purest grade of olive oil, obtained solely through mechanical means, without solvents or excessive heat. Its maximum free acidity is 0.8%, a benchmark of superior quality. Produced by cold-pressing fresh olives, it retains phenolic compounds, vitamin E, and monounsaturated fatty acids, which support cardiovascular health.

Cold extraction (below 27 °C) preserves fruity flavor, aroma, and antioxidants such as oleuropein and hydroxytyrosol. Leading producers include Spain, Italy, Greece, and Portugal. In Brazil, consumption grows annually, especially in salads, dressings, and finishing dishes. Extra virgin oils exhibit varied sensory notes: bitterness, pungency, and fruitiness, indicators of freshness and authenticity.

Authenticity of extra virgin olive oil is a concern, as adulteration with lower-quality oils is common. Certification seals like DOP (Protected Designation of Origin) or the International Olive Council help guarantee origin. For consumers, tips include checking the harvest date, noting that color does not indicate quality, and storing in a cool, dark place. It should not be heated above 180 °C but is ideal for raw preparations and gentle sautéing.
