What Is Coffee Cupping and How Professionals Do It

If you’ve ever wondered how coffee experts decide which beans are worth buying—or how roasters choose the best roast profile—you’ve likely heard the term ‘cupping.’ But what exactly happens in a coffee cupping session, and why does every serious coffee professional rely on it? This guide breaks down the standardized process used worldwide to assess coffee quality purely by taste.

Coffee cupping is a standardized evaluation method where 10 grams of ground coffee are brewed with 93–100°C water in a cup, then assessed for aroma, flavor, acidity, sweetness, and aftertaste—without sipping. Each cup is scored immediately after tasting, with the coffee spat out to maintain palate clarity across multiple samples.

What Is Coffee Cupping?

Coffee cupping, or “coffee cup testing,” is the sensory method used to judge coffee quality based exclusively on taste and smell. The professionals who conduct these evaluations are called cuppers or “tasters.” In a standard cupping session, 10 grams of freshly ground coffee are placed into a pre-warmed cup, then infused with 93–100°C water. The brew is stirred, left to settle so the grounds can sink, and the foam is skimmed off before evaluation begins.

The taster first smells the dry coffee grounds and brewed coffee, assessing fragrance and aroma. Then they break the crust—that layer of floating grounds—and sniff again. Next comes the actual cupping: instead of sipping, the taster uses a spoon to slurp the coffee forcefully, coating the entire mouth to evaluate its acidity, sweetness, bitterness, balance, and any off-flavors. Each coffee is tasted at multiple temperatures—hot, warm, and cooled—to track how its profile evolves.

Why Coffee Professionals Cup Coffee

Cupping serves several essential purposes in specialty coffee:

• Selecting Preferences: It helps individuals identify the flavors and profiles they personally enjoy in coffee.
• Comparing Roast Methods: For coffee beans from the same origin, different roast levels and techniques can be compared to determine which roast brings out the best qualities.
• Evaluating Origins: When roast profiles are consistent, cupping helps determine which geographic origins produce the most desirable beans.

By removing variables like brew method or preparation style, cupping offers a pure, repeatable way to assess intrinsic coffee traits such as sweetness, acidity, body, and cleanliness of cup.

What You Need for Coffee Cupping

To run a proper cupping session, you’ll need the following equipment and materials:

• A flat table
• Cupping spoons (one per person)
• Cupping forms or score sheets (one per person)
• 4–5 different types of both green (raw) and roasted coffee beans
• About 12 wide-mouthed glass cups or bowl-style cupping bowls
• Hot water (just off boil, around 93–100°C)
• A waste bin or spittoon
• A clean towel or cloth
• (Optional) A grinder set to a medium-fine grind similar to sea salt

Note: Green (unroasted) coffee comes in two types—in-shell (with husk and silver skin intact, often used for planting) and hulled (with husk and silver skin removed). Roasted coffee is simply green coffee that has been roasted.

How to Cup Coffee: Step-by-Step

Here’s how a standard cupping session unfolds, based on the traditional methodology used by professionals and roasteries like FrontStreet Coffee:

1. Setup: Arrange 4 types of green beans and 4 types of roasted beans on the table. Place 4 cupping cups in position for each set.
2. Smell the Dry Coffee: Pick up the container of beans (either green or roasted) with both hands and bring it close to your nose. Gently sniff each sample. For green beans, check for mustiness or fermentation defects. For roasted beans, assess the intensity and quality of the aroma.
3. Grind and Pour: Grind the coffee to a medium-fine consistency (roughly like sea salt), then add 10 grams into each cup. Slowly pour hot water (93–100°C) over the grounds to fully saturate them. Use about 150–180ml of water per cup.
4. Stir and Settle: After pouring, let the coffee brew for 3–4 minutes. Then, using a spoon, gently stir the crust once or twice. Rinse the spoon with hot water after each cup and smell the rinse water—it can hint at the coffee’s aromatic profile.
5. Skim the Foam: Remove the foam or crust that forms on the surface using a spoon.
6. Smell the Brewed Coffee: Before tasting, sniff the brewed coffee. A good coffee will have a clean, fragrant aroma—fruity, floral, nutty, or chocolatey. Avoid putting your nose into the liquid; assess the rising steam.
7. Taste the Coffee: Do not sip. Instead, take a spoonful of coffee, slurp it forcefully (like sipping soup noisily), and spray it across your entire palate. Focus on the aroma released in the mouth, then assess the flavors—including acidity, sweetness, bitterness, balance, and any defects. Spit the coffee into a waste bin and rinse your spoon in warm water before moving to the next sample.
8. Evaluate Across Temperatures: Taste each coffee at different stages: hot, warm, and cooled. Some coffees may develop unwanted acidity or bitterness as they cool. Take notes on how the flavor evolves.

Frequently Asked Questions

What is the standard coffee-to-water ratio for cupping?

The standard coffee cupping ratio is 10 grams of coffee to approximately 150–180 milliliters (5–6 ounces) of water. This approximates a 1:15 to 1:18 brew ratio, ensuring enough strength for flavor evaluation without over-extraction.

Why do cuppers slurp coffee instead of sipping it?

Cuppers slurp coffee loudly to aerate it and spray it across the entire mouth. This technique coats the tongue and palate evenly, allowing the taster to assess acidity, sweetness, bitterness, and aroma simultaneously from different parts of the mouth.

What are the main attributes evaluated in coffee cupping?

Cuppers assess five main attributes: fragrance/aroma (from dry and wet grounds), flavor (taste notes), acidity (brightness), sweetness (sugar-like notes), and aftertaste (finish). They also note body, balance, uniformity, and any defects or off-flavors.

Do you swallow the coffee during a cupping session?

No. Cuppers do not swallow the coffee. Each sample is spat out after tasting to prevent flavor carryover and maintain a clean palate for evaluating subsequent cups.

Can cupping be done with any type of coffee?

Yes. Cupping is used for both single-origin and blended coffees, and across all roast levels. However, the same roast level and brewing parameters should be used when comparing different coffees to ensure a fair evaluation.
