Forget wine tasting, try some olive oil
Wine gets the tasting rooms and the swirling glasses, but olive oil is just as alive to origin, variety and skill. Learn a few simple moves and a supermarket bottle and a great single-estate oil stop tasting the same — which is the fastest way to stop overpaying for the wrong one.
We are happy to believe a wine tastes of its slope, its grape and its maker, yet we buy olive oil as if one bottle were much like another. It is not. A good extra virgin carries its variety, its region and the care taken at harvest as clearly as any wine — grassy or ripe, gentle or fiercely peppery, clean or faintly rancid. The good news is that tasting olive oil takes no special palate and no equipment : just a little method and the willingness to pay attention. Once you have done it a few times, you cannot un-know the difference.
How the professionals taste
Panel tasters use a deliberately odd ritual, and every step has a reason. They pour a little oil into a small glass, cup it in one hand and cover it with the other to warm it to around body temperature, which releases the aromas. They swirl, uncover and smell deeply. Then they take a sip and slurp air across it — an ungainly, hissing draw that sprays the oil around the mouth and lifts its volatiles to the nose from behind. Finally they note the finish : the peppery catch at the back of the throat that often arrives a beat later. Officially they use a coloured glass — usually blue — so the oil’s colour cannot bias the verdict.
Why colour tells you nothing
That blue glass is the great myth-buster. Colour, in olive oil, is not a quality signal : a deep green oil may be mild and a pale golden one intensely pungent, because colour tracks chlorophyll and ripeness, not goodness. Professionals hide the colour on purpose so it cannot mislead them, and you should mentally do the same. Judge an oil by smell and taste, never by how green it looks in the bottle — that greenness is often exactly what the marketing is counting on.
| Step | Wine tasting | Olive-oil tasting |
|---|---|---|
| Vessel | Clear stemmed glass | Small glass, often coloured blue |
| Temperature | Served cool to warm | Warmed in the hand to ~body heat |
| Look | Colour matters | Colour deliberately ignored |
| Aroma | Swirl and sniff | Cover, warm, then sniff |
| Taste | Sip and swirl | Sip and slurp air across it |
| The ‘good’ signs | Balance, length | Fruitiness, bitterness, a peppery finish |
The three things you are judging
Tasters score an extra virgin on three positive attributes. Fruitiness is the fresh smell of the olive — green grass, tomato leaf, apple, almond. Bitterness is a taste on the tongue, and — this surprises people — it is a virtue, a sign of healthy polyphenols. Pungency is that peppery burn at the back of the throat, another polyphenol marker. A fresh, well-made oil shows all three ; a tired or faulty one tastes flat, greasy, or of nothing much. Bitter and peppery are not defects to apologise for — they are the oil telling you it is alive.
Try it at home tonight
- Pour a spoonful into a small glass, cup it in your hand a minute to warm it, then smell.
- Slurp a sip with air, and notice the peppery finish — count how long it lasts.
- Taste two oils side by side — a cheap blend and a good single-estate — and the gap becomes obvious.
- Ignore the colour ; trust your nose and throat. Bitter and peppery mean fresh, not spoiled.
Tasting olive oil: common questions
Do you really taste olive oil like wine?
Yes — you warm it, smell it, then slurp a sip with air to spread it around the palate, judging fruitiness, bitterness and a peppery finish.
Why do professionals use a blue glass?
To hide the oil’s colour, which is not a quality signal, so it cannot bias their judgement of aroma and taste.
Is bitterness a fault in olive oil?
No — a moderate bitterness is a positive sign of fresh, polyphenol-rich extra virgin, not a defect.
What does the peppery throat-catch mean?
That pungency is another marker of healthy polyphenols and freshness; a good young oil often makes you cough slightly.
Does colour indicate quality?
No. Colour reflects chlorophyll and ripeness, not goodness — a pale oil can be excellent and a deep green one ordinary.
The single most useful thing you can do is taste two oils side by side : a cheap supermarket blend and a proper single-estate extra virgin, warmed in the hand and slurped with a bit of air. The gap is not subtle, and once you have felt it you will never again buy oil as if all bottles were the same. And ignore the colour — that is the trade’s favourite bit of theatre. Bitter and peppery are not faults to forgive ; they are the oil proving it is fresh and alive.
