How to spot adulterated olive oil

A large part of the “extra virgin” on the market is not what it claims to be. Six signs by which you can recognise the real thing.

Olive oil is among the most frequently adulterated foods in the world. It is cut with cheaper vegetable oils, with inferior product that has been chemically “deodorised” into neutrality — and then sold as top quality.

You don’t have to be a sommelier to protect yourself. Six pointers go a long way.

The six signs

1. The price. Genuine extra virgin made by hand cannot cost 4 euros a litre. The harvest alone costs more.

2. The origin. “Blend of EU countries” is a warning sign. The more precise the detail — region, hill, variety — the better.

3. The date. A harvest or bottling date rather than just a best-before. Oil is a juice, not a tinned good.

4. The glass. Dark glass or a tin. Light is the oil’s fastest enemy.

5. The acidity. Good extra virgin sits well below the legal limit of 0.8%. Reputable producers state the value.

6. The taste. Fruity, bitter, a scratch in the throat. If it tastes of nothing, something is missing.

The Letter from the Hill

When the next harvest begins, you’ll be the first to know.

Blossom, summer, harvest, a new vintage: we only write when the hill has something to tell — and when a vintage is running low.
