How to taste coffee like a cupper

Most coffee drinkers, even enthusiastic ones, taste coffee in a fairly vague way. "It's nice." "It's bitter." "It's strong." Professionals taste coffee in a structured way called cupping, and the structure is what unlocks the vocabulary. Once you know what you are looking for and in what order, suddenly you can describe a cup the way a sommelier describes a wine.

The good news: you can do a perfectly serviceable home version of cupping with nothing more than a kettle, a grinder, a spoon, and a couple of mugs.

The basic protocol

Weigh out 12 grams of coffee into a small glass or mug. Grind medium-coarse, like sea salt. Pour 200ml of water just off the boil directly onto the grounds. Set a timer for four minutes.

While it steeps, lean over the cup and smell. This is the "crust" — a layer of grounds floating on top — and it traps a lot of the most volatile aromatics. Note what you smell. Be specific: not just "fruity" but which fruit. Stone fruit? Citrus? Tropical?

At four minutes, take a spoon and break the crust by stirring three times. Bring your nose right down. The smell that comes up at this moment is the most intense your cup will be. Note it.

Skim the floating grounds off with two spoons. Wait until the cup cools to roughly 60°C — about another four minutes. Now taste, by slurping a spoonful loudly off the back of the spoon. The slurp aerates the coffee across your whole palate at once.

What to actually look for

Cuppers evaluate four main attributes, in this order: aroma, acidity, body, and finish. Train yourself to consciously assess each one.

Acidity is the brightness — the snap, the sparkle, the thing that makes a cup feel alive. It is not the same as sour. Good acidity is like biting a ripe apple. Bad acidity is like sucking a lemon.

Body is the weight of the coffee in your mouth. Compare it to milk: skimmed, semi-skimmed, full-fat. A washed Kenyan often feels light; a natural Brazilian often feels heavy.

Finish is what is left after you swallow. Does the flavour linger? Does it disappear immediately? Is the aftertaste pleasant or astringent?

Then: flavour. This is where vocabulary helps. The SCA tasting wheel groups flavours into families — fruity, floral, nutty, sweet, spicy, roasted. Start broad and narrow down. "Fruity" → "berry" → "blueberry". Even if you are wrong, the act of trying to be specific sharpens your palate.

Comparing cups

Cupping really comes alive when you cup two or three coffees side by side. Buy three different single-origin beans — say, an Ethiopian, a Colombian, and a Brazilian — and brew them at the same ratio at the same time. The differences will leap out at you in a way they never do in isolation.

Do this once a month and within half a year you will start identifying origin styles by taste alone. That is when coffee stops being a beverage and starts being a hobby.
