What Is Coffee Cupping and How Is It Done?

Ever wondered how coffee professionals decide which beans to buy or which coffees score highest in global competitions? The answer lies in coffee cupping—a standardized, sensory evaluation method used at origin and in roasteries to assess green coffee quality before purchase or roast.

Coffee cupping is a structured process where three cups of the same coffee are evaluated for sweetness, acidity, bitterness, aftertaste, aroma, and overall quality. Using 10g of pre-roasted coffee per cup, hot water at 100°C, and a specific sequence of steps, cuppers identify defects and flavor profiles to make informed buying or roasting decisions.

What Is Coffee Cupping?

Coffee cupping is like wine tasting but for coffee. It’s a professional, objective way to judge a coffee’s sweetness, acidity, bitterness, aftertaste, aroma, and overall quality. Used widely at coffee origins and in production countries, cupping is the most direct method to experience a coffee’s unique flavors. When sourcing green coffee beans, cupping helps determine whether to buy a particular lot.

Why Three Cups Per Coffee?

Each coffee is cupped in triplicate—three cups of the same preparation—to ensure accuracy. A single defective bean can skew the flavor of one cup, so evaluating three helps cuppers confirm consistency and avoid misjudging a lot based on one flawed sample.

How to Cup Coffee: The DISCOVERY Method

The following steps outline the DISCOVERY-style cupping method, a clear and widely used approach:

1. Gather Your Tools

You’ll need:

• 10g of coffee beans × 3 cups (use coffee roasted to just before second crack; grind on FujiRoyal R-202 grinder at setting ⑥)
• 3 identical glass cups or containers
• 100cc of hot water × 3
• Cupping spoons (or regular spoons can work—some prefer them)
• A timer
• A cup for rinsing your spoon between samples
• A cup for spitting out coffee liquid

Why three cups? To avoid scoring a coffee unfairly due to a single defect bean. Consistency across all three cups validates the cupping results.

2. Smell the Dry Coffee Grounds (DRY)

Before adding water, evaluate the aroma of the dry grounds. Gently swirl or shake the cup and sniff with your hand cupped over the top to capture the volatile aromatics.

3. Pour Hot Water & Evaluate the Crust (CRUST)

Pour 100cc of 100°C water into each cup. Start the timer for 3 minutes. As the coffee brews, a crust forms on top. Lean in and sniff deeply to perceive the evolving “crust” aromas.

4. Break the Crust

At 3 minutes, use your cupping spoon to break the crust. Dip the spoon to the bottom of the cup and sweep upward 3 times, moving from the center outward to release trapped aromas. Keep your nose close during this step.

5. Remove Floating Particles

Skim off any foam or floating coffee particles from the surface using your spoon. This prevents choking or off-flavors when tasting.

6. Taste the Coffee

Using the spoon, slurp the coffee forcefully—as if whistling—to aerate it and spray it across your palate. Focus on detecting sweetness, acidity, bitterness, aftertaste, body, texture, balance, and uniformity. A common technique is to place the spoon near your lower front teeth, tilt slightly, and inhale sharply. Slurping may produce a “blowing” sound—that’s normal.

7. Assess as It Cools

Taste the coffee again as it cools. Different flavor notes emerge at various temperatures, revealing more about the coffee’s character.

Repeat this process regularly to train your palate and build a mental library of coffee flavors and aromas.

How to Describe Coffee Flavors

Coffee cupping uses a sensory language similar to wine. Here are common terms:

Aroma (Dry & Crust)

• Spice, herb, nut, flower, caramel, vanilla, wine, fruit, grass
• Dry, green, earthy, fermented, burnt, smoky

Acidity

• Smooth, bright, crisp, fruity (apple, lemon, orange, peach, mango), yogurt-like
• Harsh, sour, vinegary

Body

• Oily, buttery, creamy, silky, velvety, watery, light

Aftertaste

• Long, resonant, sweet, mild, short, astringent

Cleanliness

• Clear, transparent, pure, muddy

The more you cup, the better you get at identifying and articulating these attributes. Practice makes perfect—and helps you discover new dimensions in every cup.

Cupping in Coffee Competitions

Cupping is also essential in international specialty coffee competitions like the Cup of Excellence (COE). Trained judges—both local and international—use cupping to evaluate and score coffees, determining which beans earn top honors and export opportunities.

Many people claim to dislike acidic coffee, but in cupping, acidity is a critical positive attribute. Bright, sweet acidity often correlates with higher scores and more complex flavor profiles.

Frequently Asked Questions

What is coffee cupping and why is it important?

Coffee cupping is a standardized method used by professionals to evaluate coffee quality based on taste, aroma, acidity, body, aftertaste, and balance. It’s essential for assessing green coffee before purchase or roasting, especially at origin, and ensures buyers select the best lots.

How many cups are used per coffee sample in cupping?

Three cups of the same coffee are used per sample. This helps ensure consistency and rule out defects from a single bean affecting the overall evaluation.

What grind size is used for coffee cupping?

Coffee is ground to a setting similar to what would be used just before the second crack in roasting. In the DISCOVERY method, this is a FujiRoyal R-202 grinder set to ⑥, using 10g of coffee per 100cc of water.

What temperature should water be for cupping?

Use 100°C (boiling) water for cupping. Each cup receives 100cc, and the coffee grounds are allowed to steep for around 3 minutes before breaking the crust.

How do you taste coffee during a cupping session?

Cuppers slurp the coffee forcefully from the spoon to aerate it and spread it across the palate. This helps highlight the coffee’s sweetness, acidity, bitterness, body, and aftertaste. Spitting out the coffee afterward is common to avoid overconsumption.

What are the main flavor attributes described in cupping?

Cuppers describe aromas (like fruit, spice, or floral), acidity (bright or harsh), body (light or heavy), aftertaste (long or short), cleanliness, and overall balance. These terms help standardize coffee evaluation globally.
