I sat through my first real cupping in 2015 next to a roaster who used the word “briny” to describe a coffee I would have just called “off,” and I remember thinking he’d made the word up on the spot to sound impressive. He hadn’t. Professional coffee tasters have built up a real, specific vocabulary over decades, borrowed partly from wine tasting and partly invented from scratch, and once you know it, it turns “this tastes weird” into something you can actually act on. Here’s the terminology, in plain language.
Acerbic
A sour, acrid flavor, often the result of coffee that’s been overheated, like a pot left sitting on a burner too long after brewing.
Acidity
A bright, lively quality felt at the tip of the tongue, distinct from bitterness or sourness. It’s often strongest in coffee grown at higher altitudes. Tasters generally divide it into desirable acidity (the pleasant, snappy kind that makes a coffee feel alive), sour acidity (an unpleasant, unbalanced sharpness), and process acidity (a specific tang tied to how the coffee was processed after harvest, like the tartness common in natural-processed lots).
Aftertaste
What lingers in your mouth after you swallow, driven by the vapors the coffee releases. It can range from chocolatey and spicy to carbony, and a coffee whose aftertaste turns unpleasant quickly is usually marked down by professional tasters even if the first sip was good.
Aroma
The scent of the coffee once it’s brewed, as opposed to bouquet, which is the smell of the dry or freshly ground coffee before water touches it. Aroma can carry floral, herbal, fruity, or spicy notes depending on the bean and roast.
Bitter
Tasted at the back of the tongue. Some coffees, particularly dark roasts, are intentionally bitter in a way that reads as rich rather than unpleasant. Bitterness can also show up as a flaw when it comes from over-extraction rather than roast level.
Bland
Flavorless or very lightly flavored, common in low-grown robusta, or caused by brewing with too little coffee or too coarse a grind.
Body
The weight and texture of the coffee in your mouth, sometimes called mouthfeel. Described as anything from thin and watery to rich, syrupy, or buttery. It’s one of the harder qualities to pin down by description alone, which is exactly why tasters spend so much time practicing it.
Bouquet
The smell of the ground coffee before it’s brewed, distinct from aroma, which refers to the brewed coffee’s scent.
Bright
A term paired with acidity to describe a tangy, lively taste, generally a compliment when used about a light-roast, high-altitude coffee.
Briny
An off, salty-tasting flavor found in old or overheated coffee, the flaw my roaster friend correctly identified all those years ago.
Clean
A cup with no distracting off-flavors or defects, letting the coffee’s actual character come through unobstructed. Cleanliness is one of the core scoring categories on the SCA cupping form used across the specialty coffee industry.
Earthy
A genuinely earthy, soil-like flavor, as distinct from a dirty or musty defect. Common in Indonesian and some Ethiopian coffees, where it’s usually considered a desirable part of the profile rather than a flaw.
Exotic
Unusual, distinctive flavor notes like berry or floral accents that occur naturally in the bean. This is a different category entirely from “flavored coffee,” which has flavoring added after the fact.
Finish
Closely related to aftertaste, but specifically the very last impression a coffee leaves as you swallow, before the longer aftertaste sets in. A “short finish” ends abruptly; a “long finish” lingers.
Flat
A cup with no strong characteristics at all, often the result of stale coffee that’s lost its aromatic compounds.
Flavor
In formal cupping terms, the combination of aroma, acidity, and body together, not any one quality on its own.
Fruity
A flavor reminiscent of citrus or berries, common in naturally processed coffees and high-altitude African origins like Ethiopia and Kenya.
Musty
A dirty, damp-basement flavor that usually points to poor storage, either of the green beans before roasting or the roasted coffee afterward.
Neutral
Different from flat in tone: a coffee lacking strong aromatic or flavor qualities in a positive sense, making it a reliable, unobtrusive base for blends rather than a coffee meant to stand on its own.
Nutty
An aftertaste reminiscent of roasted nuts, common in medium roasts of Central American coffees.
Rounded
A cup where acidity, body, and sweetness feel balanced against each other rather than any one quality dominating. Roasters often chase “rounded” as a goal for crowd-pleasing blends.
Spicy
Carrying the flavor of specific spices, like cinnamon or clove, usually a natural characteristic of the bean rather than an added flavoring.
Stale
A flat, cardboard-like taste in coffee that’s been exposed to air for too long after roasting or grinding. The single most common flavor defect in home coffee, and almost always fixable by buying less coffee more often.
Sweet
A smooth, even-flavored coffee with no harsh notes fighting against each other. Sweetness in coffee doesn’t mean sugar; it means the acidity, body, and flavor compounds are balanced enough that nothing tastes sharp or unpleasant.
Tone
The color and visual appearance of the roasted or brewed coffee, described as light, medium, dark, or somewhere in between.
Winy
An aftertaste reminiscent of a fine red wine, most associated with certain Kenyan and Yemeni coffees.
Woody
A dry, cardboard-adjacent flavor usually pointing to green coffee that’s aged too long before roasting, losing its brighter character along the way. Distinct from earthy, which is a desirable, dirt-like note rather than a defect.
The best way to actually learn this vocabulary is to use it while tasting, not just read it. If you want an excuse to practice, our guide to coffee adventures covers how to run an informal home cupping with friends, and once you’re roasting your own beans, our guide to the stages of coffee roasting will help you connect these flavor terms back to the roast level that produced them.
