What qualities to look for?
A good extra virgin olive oil smells of fresh olives, with a layered bouquet: cut grass, artichoke, almond, green tomato. On the palate, it is fruity, with a pleasant bitterness and a spiciness that is felt in the throat: this is not a defect, but the signature of antioxidants. Aromatic complexity and a clean finish complete the picture of a well-made oil.
What defects to avoid?
- Rancid: smell of old nuts or butter, a sign of oxidation.
- Musty/damp: stuffy smell, from olives stored poorly before milling.
- Vinegary: acetic aroma, from undesirable fermentations.
- Metallic: iron taste, from prolonged contact with metallic surfaces.
How to do a quick home test?
- Bread test: a good extra virgin olive oil enhances toasted bread without overpowering it.
- Olfactory test: smells intensely even at room temperature.
- Observation: it must be clear, without deposits or cloudiness.
