What Is Coffee Cupping and How Is It Done?

If you’ve ever wondered what professionals actually do to evaluate coffee beans—how they taste them, score them, or decide what makes one bean better than another—you’ve likely heard the term ‘cupping.’ But what exactly is cupping, and why is it such a big deal in the world of specialty coffee? Let’s break it down.

Cupping is the standard professional method for evaluating coffee beans. It uses 10 grams of coffee per 180cc of near-boiling water, a grind size between French press and pour-over, and a 3-minute steep before breaking the crust and tasting. This process reveals the bean’s true flavors, aromas, and potential for blending.

What Is Coffee Cupping?

Coffee cupping is a standardized, sensory evaluation method used by roasters, buyers, and baristas to assess the qualities of coffee beans. It’s not just casual tasting—it’s a structured way to understand a coffee’s aroma, flavor, sweetness, acidity, body, and aftertaste. More importantly, it’s the foundation for blending different beans and understanding how a green coffee might perform once roasted.

Why Cupping Matters in Specialty Coffee

In the specialty coffee world, cupping is essential. It allows professionals to taste coffee as close as possible to its natural state—without the variables of brewing devices, filters, or pressure. That means you get a clear picture of the bean’s inherent qualities. It’s also how coffee farms, importers, and roasters communicate about quality, flavor profiles, and roast potential. Without cupping, there’s no consistent way to compare beans from different regions or batches.

How to Cup Coffee: Step-by-Step

Here’s the exact method used in professional cupping sessions, based on the standard approach:

• Grind Size: Use a grind setting that’s between French press and pour-over—slightly coarser than what you’d use for drip coffee but not as coarse as traditional French press. Think of it as a mid-range, uniform grind that allows for even extraction during the steep.
• Dose: Measure exactly 10 grams of whole coffee beans per cup.
• Water Volume: Add 180cc (about 6 fluid ounces) of water. That water should be freshly boiled—around 93–96°C (200–205°F)—to ensure proper extraction.
• Steeping Time: Let the coffee brew, undisturbed, for 3 minutes. During this time, the grounds infuse with the water, and a crust forms on the surface.
• Smelling the Aroma: After 3 minutes, the coffee will have cooled slightly to around 70°C (160°F). Before breaking the crust, lean in and smell the rising aromas—that’s your first impression of the coffee’s fragrance.
• Breaking the Crust: Using a spoon, gently stir the surface of the coffee 3 times. This breaks the crust and releases more aromas. As you do this, smell deeply again—many of the most volatile aromatic compounds are released at this stage.
• Removing the Foam and Grounds: Take a spoon and carefully skim off the foam and any floating grounds from the surface. Don’t taste anything yet.
• Tasting: Now, take a spoonful of the brewed coffee, slurp it forcefully (to aerate it and spread it across your palate), and evaluate. Note the flavors, acidity, sweetness, body, and aftertaste. Try to describe what you taste using familiar flavor terms—this helps build your coffee palate.

Key Ratios and Measurements in Cupping

To replicate professional cupping conditions exactly, always stick to these parameters:

• 10 grams of coffee
• 180cc of water
• Grind size: between French press and pour-over
• Water temperature: near boiling (just off the boil)
• Steep time: 3 minutes

These numbers matter. Changing the dose, water amount, or time—even slightly—will alter the extraction and therefore the cup profile you’re evaluating.

Frequently Asked Questions

What is coffee cupping and why is it important?

Coffee cupping is a standardized method used by professionals to evaluate coffee beans. It helps assess aroma, flavor, acidity, body, and aftertaste without the variables of brewing methods. It’s crucial for roasters, buyers, and blenders to understand a coffee’s inherent qualities and potential.

How much coffee do you use for cupping?

You use exactly 10 grams of whole bean coffee per 180cc (about 6 ounces) of water. This ratio is standard in professional cupping to ensure consistency and comparability across different coffees.

What grind size is used for cupping?

The grind size for cupping is between French press and pour-over—coarser than drip but finer than traditional French press. It should be uniform to ensure even extraction during the 3-minute steep.

How long do you let coffee steep during a cupping?

Coffee is steeped for exactly 3 minutes. After that, you break the crust, remove the foam, and taste. This timing is critical for balanced extraction in the cupping format.

What temperature is the water for coffee cupping?

The water should be freshly boiled, typically around 93–96°C (200–205°F). It’s poured over the grounds just off the boil, then allowed to cool slightly during the 3-minute steep.

What do you do with the coffee crust during cupping?

After steeping, you break the crust on the surface with a spoon 3 times while smelling deeply. Then you skim off the foam and floating grounds before tasting the coffee beneath.
