What Is Coffee Cupping and How It Works

Ever wondered how coffee professionals decide which beans are worth buying—or roasting? The answer isn’t guesswork or brand hype. It’s a standardized sensory method called coffee cupping. Used globally by roasters, importers, and baristas, cupping lets tasters assess coffee quality based solely on taste and smell. Here’s how the pros do it—and how you can too.

Coffee cupping involves using 10 grams of ground coffee per cup, pouring 100°C water over it, letting it steep, then evaluating aroma, flavor, acidity, sweetness, and aftertaste—without swallowing. This process helps identify the best beans and roast profiles by taste alone.

What Is Coffee Cupping?

Coffee cupping, or “coffee cup testing,” is the standard method for evaluating coffee quality through sensory assessment. The professionals who conduct these evaluations are called cuppers or Q graders. Unlike casual sipping, cupping is structured: every variable is controlled to focus purely on the coffee’s intrinsic traits.

Why Cup Coffee? The Purpose of Cupping

Cupping serves three key purposes:

• To scientifically assess coffee quality and choose preferred beans.
• To compare how different roast levels affect the same origin.
• To evaluate how different origins perform under the same roast.

By isolating variables, cupping reveals how origin, processing, and roast influence flavor—helping roasters select beans and customers understand their preferences.

Types of Coffee Beans Involved

Coffee beans fall into two main categories: green (raw) and roasted. Green beans are further divided into:

• With husk : Includes inner fruit skin and silver skin; often used for planting. The husk preserves moisture, prevents mold, and allows storage for 1–2 years at room temperature.
• Without husk : Has had the fruit and silver skin removed.
• Roasted beans : Green beans that have been roasted.

What You Need for Coffee Cupping

To properly cup coffee, gather these essentials:

• One table
• Cupping forms (one per person)
• 4–5 types of both green and roasted coffee samples
• Spoons
• About 12 wide-mouth glass cups
• Boiling hot water
• A trash bin

How to Cup Coffee: Step-by-Step

Follow this structured process to get reliable, repeatable results:

1. Set Up: Arrange 4 types of green beans and 4 types of roasted beans on the table. Place 4 cups in designated spots for each.
2. Smell the Raw Beans: Pick up bowls of both green and roasted beans with both hands, bring them to your nose, and gently sniff. Check green beans for mold; assess roasted beans for aroma strength and character.
3. Brew the Coffee: Add 10g of ground coffee to each cup. Slowly pour 100°C water into each. Let it sit briefly, then stir each cup thoroughly with a spoon. Rinse the spoon with hot water after each stir and smell the rinse water—it can hint at the cup’s profile. Leave the coffee to settle so grounds sink.
4. Observe Dissolution: Watch how the coffee grounds dissolve and settle. This can offer early clues about extraction quality.
5. Smell the Brew: Don’t put your nose into the liquid. Instead, sniff the rising steam. A clean, aromatic, fruity, or floral scent signals quality. Avoid coffees with earthy, medicinal, or foul odors.
6. Taste the Coffee: Do not sip or swallow. Use a spoon to scoop coffee liquid, then slurp it loudly (like hot soup) to aerate it. Let the coffee hit your palate, especially near the front teeth, then move it around your mouth to assess acidity, sweetness, bitterness, and texture. Spit the coffee into the trash bin and rinse your spoon in warm water before the next sample.

Evaluate each coffee at different temperatures: hot, warm, cool, and even re-heated if needed. Some coffees develop acidity as they cool. Repeat tests to confirm consistency.

Frequently Asked Questions

How much coffee is used in a standard cupping session?

A standard cupping uses 10 grams of ground coffee per cup. This measurement is consistent across professional evaluations to ensure fair comparison.

What water temperature is used for coffee cupping?

Coffee cupping requires water heated to 100°C (boiling point). This high temperature ensures proper extraction during the brief brewing period.

Do you swallow the coffee during cupping?

No, you do not swallow the coffee during cupping. Instead, you slurp it into your mouth and spit it out afterward to avoid flavor carryover between samples.

How many types of coffee should be tasted in one session?

A typical cupping session includes at least 4–5 types of both green (raw) and roasted coffee samples. This variety allows for meaningful comparison across origins and roast levels.

Why is it important not to swallow the coffee?

Not swallowing prevents residual flavors from affecting your taste buds during subsequent tastings. This ensures each coffee is evaluated on its own merits without interference.

What should you look for when smelling the coffee?

Look for clean, pleasant aromas like fruit, flowers, or caramel. Avoid unpleasant odors such as earthiness, medicine, or mustiness, which indicate defects or poor quality.
