Most people have never really tasted olive oil — they have only cooked with it. Yet a great extra virgin oil is as complex as a fine wine, and learning to taste it takes about five minutes. Do it once and you will never look at a supermarket bottle the same way again. Here is how the professionals do it, what the flavours mean, and how to decode a label.

The three good things: fruity, bitter, pungent

Official tasters recognise only three positive attributes in an extra virgin oil — and, surprisingly, two of them sound like faults:

• Fruity — the aroma of fresh, sound olives. It can be green (cut grass, tomato leaf, artichoke, from early fruit) or ripe (soft, sweet, almond, apple).
• Bitter — a clean bitterness felt at the back of the tongue, from green olives. A good sign, not a fault.
• Pungent — the peppery sting at the back of the throat that can make you cough. This is the signature of oleocanthal and other polyphenols — the very antioxidants that make an oil healthy. A pungent oil is a living, fresh, high-quality oil.

Bitterness and pungency are not defects to be tolerated; they are the marks of a young, well-made, polyphenol-rich oil. Bland is not better.

How to taste, step by step

1. Pour a small amount into a little glass (tasters use blue glass so colour can't bias them — colour tells you nothing about quality).
2. Cup the glass in one hand and cover it with the other to warm it gently to body temperature.
3. Smell deeply — grass, tomato, almond, apple, green banana?
4. Sip a little, then draw air in over the oil through pursed lips ("strippaggio") to spread the aroma across your palate.
5. Notice the sequence: fruit first, then bitterness on the tongue, then the pungent kick in the throat as you swallow.

The faults to spot

Trained panels also screen for defects, any of which disqualifies an oil from "extra virgin":

• Rancid — stale, like old nuts or crayons (oxidation from age, light or heat). The most common fault in supermarket oil.
• Fusty (atrojado) — olives fermented in the heap before milling.
• Musty — damp, mouldy fruit.
• Winey / vinegary — sharp, fermented notes.
• Muddy sediment — from oil left too long on its lees.

Reading the label

• "Extra virgin" — the only grade worth buying for flavour and health.
• Harvest date — fresher is better; oil is not wine, and fades within about 18–24 months. A harvest date beats a distant "best before."
• Variety — Picual (peppery, robust), Arbequina (soft, buttery), Hojiblanca (balanced): the variety predicts the flavour. (See The Great Olive Varieties.)
• Origin / DOP — a named estate or Protected Designation of Origin (Baena, Priego de Córdoba, Sierra Mágina…) signals traceability and quality. (See The DOP Olive Oils of Andalusia.)
• Dark glass or tin — light is oil's enemy; avoid clear bottles that have sat under shop lights.

At the villa

A guided olive-oil tasting — comparing a fiery Picual with a gentle Arbequina, straight and on warm bread — is one of the most memorable things you can do near Cortijo Bujio. (See olive oil around Montefrío.)

Frequently asked questions

Why does good olive oil make me cough? That peppery throat-sting comes from oleocanthal and other polyphenols — the antioxidants that make the oil both flavourful and healthy. A cough-inducing oil is a sign of freshness and quality, not a fault.

Are bitterness and pungency bad? No — they are two of the three official positive attributes of extra virgin olive oil, along with fruitiness. They indicate a young, well-made, antioxidant-rich oil.

Does the colour tell me anything? No. Professional tasters use coloured glasses precisely so colour can't mislead them. Green or gold, colour is not a measure of quality.

What should I look for on the label? "Extra virgin," a recent harvest date, the olive variety, a named origin or DOP, and dark glass or tin to protect the oil from light.
