My grandfather would squeeze olives between his fingers until his knuckles turned white. He always said that good oil isn't made by a machine, but by the patience of those who wait for the right moment to harvest.
When I read "extra virgin" on a supermarket label, I often think about how little that word alone truly says. Here's how to learn to look beyond it, before putting a bottle in your cart.
What "extra virgin" really means
European law (EC Regulation 2568/91) divides olive oils into precise categories. Only extra virgin has an acidity below 0.8%, is extracted solely by mechanical means, and passes a sensory test ("panel test") without defects.
But beware: "extra virgin" only means that the oil meets these minimum legal requirements. It doesn't say if it's fresh, good, or genuine. For that, you need other clues.
Acidity: the first number to look at
Free acidity primarily tells one thing: how quickly the olives were processed after harvesting. The longer it takes, the higher the acidity.
The legal limit is 0.8%. For values referring to a specific vintage or batch, it is important to consult the current documentation and not generalize a single result.
Color tells you nothing
A common mistake: judging oil by its bright green color. In reality, color depends on the variety and ripeness, not quality. It's no coincidence that official tastings use dark glasses, specifically to avoid being influenced by color.
Tasting it: fruity, bitter, pungent
The most reliable way to judge an oil is to taste it. Three signs to look for:
- Fruity โ the scent of the olive itself, sometimes freshly cut grass or artichoke. If it's missing, the oil is probably old.
- Bitter โ on the tongue, this is not a defect: it's a sign of polyphenols.
- Pungent โ that slight tingling in the throat. A sign of a rich and vibrant oil, not a defect.
Conversely, avoid: rancid, "cooked," or vinegary notes โ these are true defects that downgrade the oil regardless of what the label says.
What to look for on the label
Four things, in order of importance:
- Origin of the olives โ "Produced in Italy" or a specific region, not "blend of oils originating from the European Union."
- Batch number โ a serious producer can tell you the history of that batch.
- Organic certification โ with the code of the certifying body, not just the word written.
- Harvest year โ different from the expiry date.
Why a short supply chain makes a difference
In large-scale distribution, extra virgin olive oil is often a blend of batches from different countries, mixed for a consistent taste. A legitimate model, but far from an oil tied to a specific territory.
We work differently: my family and I cultivate about 13,000 olive trees in Roccabernarda, Calabria. Harvesting is physical work, concentrated in a few weeks between October and December. For processing and batch characteristics, refer to the product sheet and current packaging.
A final practical tip
Store the oil in the dark, in a cool place, away from heat sources โ not in the refrigerator, which only makes it cloudy unnecessarily. And consume it within a few months of opening: unlike wine, oil does not improve with age.

In short
Look at the acidity (the lower, the better). Look for a precise origin, not a generic blend. If you can, taste it: a true fruitiness, a bitterness and pungency that don't scare you, no hint of rancidity.
