Extra Virgin Olive Oil

Extra virgin olive oil is the highest trade category for olive oil. It must be obtained directly from olives by mechanical or other physical means, without refining and without treatment that alters the oil's natural characteristics.

But the classification is only the starting point. Two extra virgin olive oils can differ greatly in freshness, taste, origin, polyphenol content and documented quality. That is where the premium difference begins.

What does extra virgin olive oil mean?

Extra virgin olive oil is a category of virgin olive oil. That means it comes from olives and is extracted using mechanical methods such as milling, centrifugation and filtration.

To be called extra virgin, the oil must meet both chemical and sensory requirements. It cannot simply "look right" in an analysis. It must also have fruitiness and be free from sensory defects.

An oil that fails the sensory requirements cannot be saved by low acidity. And an oil that tastes clean but fails the chemical criteria cannot be classified as extra virgin either.

The key requirements

The best-known requirement is free acidity, expressed as oleic acid. For extra virgin olive oil it must not exceed 0.8 g per 100 g of oil.

Acidity says something about the condition of the raw material and how the olives were handled before and during extraction. Lower acidity is often positive, but it is not the whole story. Taste, oxidation, purity and freshness also matter.

Other analytical values, including peroxide value and UV absorbance, are used to assess oxidation, freshness and possible quality deterioration. Together, these values give a more complete picture than acidity alone.

Sensory quality: fruitiness without defects

Extra virgin olive oil must have positive fruitiness and be free from defects. Defects may include rancidity, mustiness, fermented notes or wine and vinegar character.

This means bitterness and pepperiness are not faults in themselves. On the contrary, they can be positive attributes when clean and balanced. In oils with a strong phenolic structure, bitterness and pepperiness are often more pronounced than in mild standard oils.

Extra virgin is not automatically premium

Extra virgin is the highest baseline classification, but the category contains a wide range. An anonymous bulk product and a traceable early-harvest oil can both be extra virgin, but the experience and documentation are not the same.

To judge real quality, you need to look at more questions:

when the olives were harvested
how quickly they were milled
which cultivars and origin the oil has
how the oil has been stored and bottled
whether analysis and batch information are available
how the flavour profile is structured

For Vala Selection, extra virgin olive oil is the baseline, not the destination. The important part is the combination of Korčula origin, early harvest, traceable batch, HPLC analysis and a flavour profile with green fruitiness, bitterness and a peppery finish.

The difference from "olive oil" and refined oil

When a bottle is sold simply as "olive oil", it is often a blend of refined olive oil and a smaller proportion of virgin olive oil. Refining can make a defective oil more neutral, but it also removes much of the natural flavour profile.

Extra virgin olive oil is not refined. It therefore carries more of the raw material's origin, harvest timing and handling. This is also why differences in quality can be clear in aroma, mouthfeel and finish.

Extra virgin and polyphenols

The extra virgin classification does not itself mean the oil is high in polyphenols. Polyphenols are affected by cultivar, ripeness, harvest, milling and storage.

A high-polyphenolic extra virgin olive oil therefore needs to meet the baseline requirements and show more: documented polyphenol content, ideally through a method such as HPLC analysis.

This is especially important when the oil is communicated with reference to the EU-authorised health claim on polyphenols and oxidative stress.

Extra virgin, cold pressed and cold extraction

"Cold pressed" is often used as a quality phrase, but extra virgin and cold pressed do not mean the same thing. Extra virgin is a quality category. Cold pressed or cold extraction describes temperature and method during extraction.

Many modern high-quality oils are made using centrifugation rather than a traditional press, which makes "cold extraction" more accurate in many cases. What matters is that temperature is controlled and that the oil is not treated in a way that changes it.

More on the term here: cold pressed olive oil.

How Vala Selection uses the classification

Vala Selection treats extra virgin as a minimum requirement. From there, we add what actually helps the customer understand the oil: origin, batch, harvest, sensory profile and analysis.

The reference batch 2025-VL-MIR-001 is an example of that level. It is extra virgin, but that is not the most interesting thing about it. What matters more is that it is traceable, analysed and selected for a clear style: fresh green fruitiness, structured bitterness and a peppery finish.
