What Is Coffee Cupping? The Professional Tasting Method Explained

When you buy a bag of specialty coffee, how do you know if it’s truly high-quality? Most coffee professionals don’t rely on a single sip or marketing claims—they use a standardized method called coffee cupping to evaluate aroma, flavor, and defects.

Coffee cupping is done by pouring 100°C hot water over 10 grams of freshly ground coffee in a cup, letting it steep, then tasting without swallowing. Each cup is assessed for fragrance, aroma, acidity, sweetness, bitterness, and cleanliness, with the entire process repeated across multiple samples for comparison.

What Is Coffee Cupping and Who Does It?

Coffee cupping—also called coffee cup testing—is the professional method used to judge coffee quality purely by taste. The experts who perform these evaluations are called “cuppers” or “Q Graders.” The goal isn’t just to find good coffee, but to understand how origin, processing, and roast level affect flavor.

Why Do Professionals Cup Coffee?

Specialists cup coffee for three main reasons: to scientifically assess quality and choose preferred beans, to compare different roast profiles of the same origin, and to evaluate how different growing regions perform under the same roast approach. This method removes guesswork and highlights subtle differences most drinkers miss.

What Are Green and Roasted Coffee Beans?

Coffee beans come in two main forms: green (raw) and roasted. Green beans are further divided into:

• Unhulled green beans: These still have their outer husk and silver skin intact. They can be used for planting and store well for 1–2 years at room temperature due to the protective layers.
• Hulled green beans: These have had the husk and silver skin removed.

Roasted coffee beans are simply green beans that have been roasted to develop flavor.

What You Need to Cup Coffee

To properly conduct a coffee cupping session, you’ll need:

• A table
• Cupping forms (one per person)
• At least 4–5 types of both green and roasted coffee beans
• Wide-mouthed glass cups (around 12 in total)
• Boiling hot water
• A trash bin
• And you’ll observe the coffee’s dissolved residue after the grounds settle.

How to Cup Coffee Step by Step

Here’s how professionals actually perform a coffee cupping, based on the standard method used at specialty roasters like FrontStreet Coffee:

• Set up: Arrange 4 types of both green and roasted beans on the table, with 4 cups positioned for each. Use one cup per sample.
• Smell the beans: Before brewing, smell both green and roasted beans. Lift the container to your nose and gently sniff. For green beans, check for mold; for roasted, assess fragrance intensity and quality.
• Add ground coffee: Grind the beans and place them in cups. Pour 100°C water over 10 grams of coffee in each cup.
• Stir and clean spoons: After pouring, let the coffee bloom and settle. Stir each cup with a spoon, then rinse the spoon with hot water immediately. Before rinsing, smell the spoon—it can hint at the coffee’s profile.
• Smell the brewed coffee: Lean in to sense the rising steam, not the liquid itself. A good coffee will have a soft, fragrant aroma. Avoid harsh, medicinal, or earthy odors.
• Taste without swallowing: Using a spoon, slurp the coffee loudly (like hot soup) to aerate it. Let it touch your front teeth first, then move it around your mouth. Do not swallow—spit it into a waste bin. Rinse the spoon in warm water before the next sample.
• Evaluate at different temperatures: Always taste the coffee hot, then as it cools, and again when lukewarm or cold. Some coffees reveal unwanted acidity or bitterness as they cool.

Frequently Asked Questions

What is the standard amount of coffee used in cupping?

The standard amount is 10 grams of ground coffee per cup. This ensures consistency when comparing different beans or roasts.

What water temperature is used for coffee cupping?

Coffee cupping uses 100°C boiling water. This temperature is critical to extract the full range of flavors during the short brewing period.

Do you swallow the coffee during cupping?

No, you do not swallow the coffee. Instead, you slurp it into your mouth and spit it out to avoid flavor carryover between samples, which could skew your taste assessments.

How is coffee evaluated during cupping?

Coffee is evaluated based on fragrance (from dry grounds), aroma (from brewed coffee), and flavor attributes such as acidity, sweetness, bitterness, balance, and cleanliness. Sensory defects are also noted.

Why do professionals smell the spoon after stirring?

Smelling the spoon after stirring can give cuppers an early sense of the coffee’s volatile aromatics, offering clues about its likely profile before tasting.

Why assess coffee at different temperatures?

Coffee flavor changes as it cools. Acidity may become more pronounced or unpleasant, while sweetness and bitterness shift. Tasting across temperatures reveals the coffee’s full range.
