Extra virgin olive oil bottle

Extra virgin olive oil is the juice of the olive obtained solely by mechanical means, without chemical solvents, and with a maximum acidity of 0.8%.

About this subject

Extra virgin olive oil (EVOO) is the highest grade of olive oil, obtained solely by cold pressing fresh olives without chemical solvents or refining. Its acidity, measured as oleic acid, is below 0.8%, a strict threshold that separates it from virgin (up to 2%) and refined oils. The process preserves natural antioxidants, vitamins, and polyphenols, giving EVOO its distinctive flavor and health benefits.

Mediterranean countries produce roughly 75% of the world's EVOO, with Spain, Italy, and Greece as top producers. Regional variations yield distinct profiles: Spanish oils are often fruity and mild, Italian ones can be bitter and peppery (e.g., Tuscan), and Greek oils are herbaceous. In Brazil, olive cultivation is expanding in states like Rio Grande do Sul and Minas Gerais, producing award-winning bottles.

EVOO is a cornerstone of the Mediterranean diet, linked to improved heart health, reduced inflammation, and longevity. To preserve its quality, store the bottle in a cool, dark place away from heat and light; dark glass helps block UV rays. Best consumed within 18 months of harvest, as beneficial compounds degrade over time.

Frequently Asked Questions

What distinguishes extra virgin olive oil from other types?

Extra virgin olive oil is produced solely by mechanical cold pressing without refining or chemical solvents. Its maximum acidity is 0.8%, whereas virgin olive oil can be up to 2% and refined oil has its flavor chemically corrected. EVOO also retains antioxidants and polyphenols intact.

How should extra virgin olive oil be stored?

Store the bottle in a cool (15-20°C), dark, and dry place away from heat and light. Avoid refrigeration, as condensation can affect taste. Use dark glass or tins to protect against oxidation, and consume within 18 months of harvest for best quality.

What are the main health benefits of extra virgin olive oil?

Rich in monounsaturated fats and polyphenols, EVOO helps lower LDL cholesterol, supports heart health, reduces inflammation, and provides antioxidant protection. Regular consumption is linked to lower rates of cardiovascular disease and increased longevity.
