About this subject

Cold pressed extra virgin olive oil is among the healthiest oils, extracted without heat or chemicals. The cold pressing method keeps processing temperatures below 27°C (80°F), preserving polyphenols, vitamins, and monounsaturated fatty acids. Regulation by the International Olive Council (IOC) and local laws, such as Brazilian standards, require extra virgin olive oil to have a maximum free acidity of 0.8% and be obtained solely by mechanical means.

This ancient technique has been refined with modern mills that crush olives into a paste, then centrifuge to separate oil from water and solids. Unlike refined oils, cold pressed oil retains bioactive compounds like oleuropein and hydroxytyrosol, linked to lower LDL cholesterol and cardiovascular protection. Major producers include Italy, Spain, Greece, and Portugal, but Brazil is expanding production in regions like Serra da Mantiqueira and Rio Grande do Sul.

Cold pressed extra virgin olive oil is prized for its fruity flavor and pungency, signs of freshness and quality. To ensure authenticity, look for geographical indications (GI) or Protected Designation of Origin (PDO) labels, along with harvest and bottling dates. Stored in a cool, dark place away from heat, it can last up to 18 months, but flavor peaks within the first few months. A note: the oil's color does not indicate quality, as it varies with olive variety and harvest time.

Frequently Asked Questions

What is the difference between cold pressed extra virgin olive oil and refined olive oil?

Cold pressed extra virgin is mechanically extracted without heat or chemicals, retaining nutrients and flavor. Refined oil undergoes thermal and chemical processes that remove impurities but also reduce beneficial compounds.

How to identify a high-quality extra virgin olive oil?

Check the label: it must state 'extra virgin', acidity up to 0.8%, harvest and bottling dates, and ideally origin seals (PDO/PGI). Prefer dark bottles and store away from light and heat.

Can cold pressed olive oil be used for frying?

Yes, but it has a lower smoke point (around 190°C) than refined oils. For high heat, choose more stable varieties. It is excellent for salads, finishing, and sauces.
