Understanding Coffee Cupping Terms: Key English-Chinese Glossary

When cupping coffee, professional tasters assess key attributes—acidity, body, aroma, and flavor—to determine a coffee’s quality. But without clear definitions, those terms can feel abstract or misleading. This guide breaks down the most common cupping terms in both English and Chinese, helping you understand exactly what trained tasters mean when they describe a coffee.

To evaluate coffee professionally, focus on four main attributes: acidity, body, aroma (wet aroma), and flavor. These are scored and described using a standardized set of terms familiar to cuppers worldwide. Below, we explain each in detail with classic flavor examples and undesirable traits.

What Is Acidity in Coffee?

Acidity is a desirable, vibrant quality in coffee, often compared to the crisp sensation in wine. It creates a dry, bright feeling on the sides of your tongue and the back of your palate. Without enough acidity, coffee tastes flat. Importantly, acidity is not the same as sourness—which is an unpleasant, sharp off-note. Good acidity adds liveliness; bad acidity ruins the cup.

Wet Aroma: More Than Just Smell

Wet aroma refers to the scents released during and just after brewing, when water interacts with ground coffee. Though closely tied to taste, aroma is sensed through smell and significantly enhances your perception of flavor. Subtle notes like “floral” or “wine-like” characteristics often come from the coffee’s wet aroma. Without a developed aroma, your basic taste experience is limited to sweet, salty, sour, and bitter.

Coffee Body: What Determines Thickness?

Body describes the physical mouthfeel of coffee—the weight, richness, and viscosity it creates on your tongue. Think of the difference between whole milk and water: that’s body. It’s influenced by the soluble oils and solids extracted during brewing. Indonesian coffees, for example, typically exhibit higher body than coffees from Central or South America. To test this, try diluting different coffees with equal amounts of milk. Coffees with more body retain their flavor better even when diluted.

Flavor: The Big Picture

Flavor is the overall impression formed by the combination of acidity, aroma, and body. It’s how all these elements work together. Professional cuppers identify both positive and negative flavor traits. Common positive descriptors include bright, caramelly, chocolaty, delicate, earthy, fruity, nutty, spicy, sweet, and winey. On the flip side, undesirable flavors range from bitter and sour to musty, rubbery, thin, and wild—terms that describe everything from over-roasted beans to processing defects.

Typical Positive Coffee Flavor Characteristics

• Bright, Dry, Sharp, or Snappy – Common in Central American coffees
• Caramelly – Candy-like or syrupy
• Chocolaty – Resembles unsweetened chocolate or vanilla
• Delicate – Subtle, perceived on the tip of the tongue (e.g., washed New Guinea arabica)
• Earthy – Soil-like quality (common in Sumatran coffees)
• Fragrant – Aromatic, from floral to spicy
• Fruity – Berry or citrus-like aromas
• Mellow – Smooth, round taste, typically low in acidity
• Nutty – Roasted nut aftertaste
• Spicy – Spice-like flavors and aromas
• Sweet – Free of harshness
• Winy – Evokes well-aged wine (common in Kenyan and Yemeni coffees)

Typical Undesirable Coffee Flavor Characteristics

• Bitter – Harsh taste at the back of the tongue, often due to over-roasting
• Bland – Neutral, unexciting flavor
• Carbony – Burnt, charcoal-like tones
• Dead – Flat, lifeless, lacking acidity and aroma
• Dirty – Musty, like eating dirt
• Earthy – Often overlaps with dirty, soil-like
• Flat – Lacks acidity, aroma, and finish
• Grassy – Fresh-cut grass aroma and flavor
• Harsh – Caustic, rough mouthfeel
• Muddy – Thick but dull
• Rioy – Starchy, like pasta water
• Rough – Tongue sensation like eating salt
• Rubbery – Burnt rubber aroma (common in dry-processed Robusta)
• Soft – Another term for bland
• Sour – Tart, unripe fruit flavor
• Thin – Lacking body, usually from under-extraction
• Turpeny – Turpentine-like flavor
• Watery – Lacks viscosity or body
• Wild – Gamey, generally undesirable (common in Ethiopian coffees)

Frequently Asked Questions

What is coffee cupping and why is it important?

Coffee cupping is a standardized method for evaluating coffee quality used by professionals. It assesses attributes like acidity, body, aroma, and flavor to identify the characteristics and potential defects in a coffee. It’s essential for sourcing, roasting, and brewing decisions in the specialty coffee industry.

How is acidity different from sourness in coffee?

Acidity in coffee is a desirable, bright, and vibrant sensation that adds liveliness, similar to acidity in wine. Sourness, on the other hand, is an unpleasant, sharp, and often off-putting taste that results from under-ripe beans or improper processing—not a positive attribute.

What does 'body' mean when describing coffee?

Body refers to the physical mouthfeel or weight of coffee on your tongue. It’s determined by the soluble oils and solids extracted during brewing. Coffees with more body feel thicker, like whole milk, while lighter-bodied coffees feel closer to water.

What are some positive flavor characteristics in specialty coffee?

Common positive flavor notes include bright, caramelly, chocolaty, fruity, floral, nutty, spicy, sweet, and winey. These attributes contribute to a balanced, complex, and pleasant cup profile.

What makes a coffee flavor undesirable or defective?

Undesirable flavors include bitter, sour, carbony, dirty, earthy (in a negative sense), flat, grassy, harsh, muddy, rubbery, thin, turpeny, watery, and wild. These can stem from over-roasting, poor processing, or brewing errors.

How can milk help identify coffee body differences?

By adding equal amounts of milk to different coffees, you can observe how much of the original flavor remains. Coffees with higher body retain more flavor even when diluted, making this a simple test for comparing body across varieties.
