Oil & Vinegar
Somewhere along the way olive oil became a connoisseur’s pour: tasted like wine, discussed by region, given as a housewarming gift. That is mostly good news. But the boutique that lets you fill a bottle from an open tap hides a catch worth knowing before you pay delicatessen prices.
There was a time when olive oil was a commodity you bought without a thought — a tin at the back of the cupboard. Then the good stuff arrived, and with it a whole culture borrowed from wine: tasting rooms, flights of single-estate oils, talk of undertones and overtones, and the boutique where you fill a glass bottle from a tap. It is a genuinely nice way to shop, and it has taught a lot of people that a fine extra virgin is as varied and interesting as any wine. It has also, quietly, created a way to sell you tired oil at a premium. Both things are true.
Why one olive tastes of a hundred things
The pleasure people discover at a tasting is real: olive oil carries terroir. The same variety grown in two valleys gives two different oils, because soil, altitude, climate and the moment of harvest all leave their mark — exactly as they do in a vineyard. A young oil pressed from green fruit tastes of cut grass, artichoke and green almond, with a peppery kick at the back of the throat; a riper pressing turns buttery, mellow, sometimes faintly of apple or ripe fruit. Learning to name those notes is most of the fun, and it is the honest heart of the whole oil-as-wine idea.
| What you taste | What it usually means | Good or bad? |
|---|---|---|
| Cut grass, green almond | Young oil, fresh, high in antioxidants | Good |
| Pepper at the back of the throat | Fresh polyphenols — a live, healthy oil | Good (it should sting a little) |
| Buttery, mild, ripe fruit | Riper harvest or gentler variety | Good, if fresh |
| Greasy, waxy, flat | Old or poorly stored | Bad |
| Crayon, putty, stale nuts | Rancid — oxidised oil | Bad — walk away |
The tap-and-fill trap
Here is the part the pretty shop does not advertise. Olive oil has three enemies — light, heat and air — and a big open dispenser on a bright counter exposes it to all three, day after day, as the level drops and fresh air fills the space above. An oil that was excellent when the drum was opened can be tired weeks later, and because you are buying it loose you get no harvest date, no sealed dark bottle, no way to know how long it has been standing. None of this means refill shops are a scam; a busy one that turns its stock over fast and keeps it out of sunlight can be superb. But treat a slow, sunlit dispenser with the same suspicion you would treat an open bottle of wine left on the bar for a month.
How to taste it properly
You do not need a laboratory. Warm a spoonful in a small glass cupped in your hand, cover it, swirl, and sniff for something green and alive — grass, tomato leaf, fresh almond. Then sip it, draw air across it, and let it reach the back of your throat. A good young oil bites there; that peppery catch is a sign of the very compounds that make the oil worth having. What you are hunting for faults is anything flat, greasy or stale. If the shop will not let you taste before you buy, that tells you something in itself.
- Oil carries terroir — taste single-estate oils side by side and the differences jump out.
- A little peppery sting is good; it signals fresh, healthy polyphenols.
- The enemies are light, heat and air — dark glass, cool shelf, tight cap.
- At a refill shop, buy where stock turns over fast and the dispenser is out of the sun.
- Always taste before you trust a label, and prize a harvest date over any tasting-room story.
Tasting and buying olive oil: common questions
Is buying olive oil on tap a good idea?
It can be, if the shop turns its stock over quickly and keeps the dispenser out of sunlight. The risk is a slow, bright dispenser where oil oxidises and you get no harvest date.
Should good olive oil be peppery?
Yes, a fresh young extra virgin often stings a little at the back of the throat. That pepper comes from the antioxidants that make the oil healthy and worth buying.
How can I tell if an oil has gone off?
Rancid oil smells and tastes flat, greasy or like stale nuts, crayon or putty. A fresh oil smells green and alive. If in doubt, it is past its best.
Why does the same olive taste different from different farms?
Because oil carries terroir — soil, altitude, climate and harvest timing all shape the flavour, just as they do in wine.
How should I store olive oil at home?
In a dark bottle or tin, cool, away from the stove and out of the light, with the cap on tight. Buy what you will use within a few months.
The oil-as-wine culture is a good thing — it got people tasting, and a fine extra virgin genuinely rewards it. But keep your wits at the pretty refill counter. A big open tap sitting in the light is oil slowly going stale, and buying it loose means no harvest date and no sealed dark bottle to protect it. Taste before you pay, hunt for that green, peppery liveliness, and treat a slow sunlit dispenser exactly as you would an open wine bottle left out for a month. Freshness beats theatre every time.
