How to taste coffee
Hot, warm, cool: three different cups — 4 min
You need three words before you need a hundred: sour, bitter, weak. Sour is a bright, sharp edge at the sides of the tongue — usually coffee that gave up too little. Bitter is a drying grip at the back — usually coffee that gave too much. Weak is neither flaw, just not enough coffee in the water.
Slurp when you taste. It feels ridiculous and works: spraying the coffee across the whole tongue and up toward the nose lets you read sweetness, acidity and texture in one pass.

Temperature is the other tasting tool nobody mentions. Scalding coffee mutes almost everything — heat itself dominates. Flavors open up around 50–60°C, and acidity steps forward as the cup cools further.
So taste every cup three times: once hot, once warm, once cool. It is genuinely three different cups, and the cool one tells the most truth.
Note
Pinch your nose mid-sip and coffee collapses into plain bitter water — most of what we call flavor is aroma reaching the nose from the back of the mouth (retronasal olfaction). It is also why coffee smells better than it tastes: some aromatics never survive the swallow.
