How to Cup Coffee Like a Specialty Roaster

When you roast coffee, especially as a professional or serious home roaster, how do you really know how good it is? The answer isn’t just in the roast color or the origin label—it’s in the cup. Specialty coffee professionals use a standardized method called cupping to assess roasted coffee’s true qualities: aroma, flavor, body, and aftertaste. If you’ve ever wondered how roasters decide which beans make the cut, cupping is how they do it.

To properly cup coffee like a pro, follow ten essential steps: measure 10g of freshly roasted and ground coffee, pour 95°C water, let it steep for 3–5 minutes, break the crust, and taste using a spoon while evaluating aroma, flavor, texture, and finish. This method is the industry benchmark for coffee assessment.

What Is Coffee Cupping?

Coffee cupping, also called cup testing, is the standard method for evaluating roasted coffee. It allows roasters, buyers, and baristas to assess key attributes—aroma, flavor, acidity, body, and aftertaste—without brewing variables like pressure or filtration getting in the way. This is how the specialty coffee industry measures quality before a coffee reaches your cup.

Why Cupping Matters to Roasters

Cupping isn’t just for professionals. For roasters—especially those honing their craft like the team at FrontStreet Coffee—it’s a daily practice. After each roast, cupping helps determine if the batch meets flavor expectations, reveals roast flaws, and guides future adjustments. It’s how you learn whether your roast is too light, too dark, or just right. Many roasters, including those training in Guangzhou, spend hours cupping each day to refine their profiles.

The Tools You Need for Cupping

Cupping doesn’t require expensive gear. You’ll typically use:

• Cupping bowls or cups (usually 150–200ml)
• Cupping spoons with a deep bowl
• Fresh roasted coffee (ideally within 1–2 weeks)
• A scale (accurate to 0.1g)
• A grinder set for a coarse, consistent grind
• A kettle with temperature control (or careful pouring from boiled water)
• A timer

The 10-Step Coffee Cupping Process

Follow these steps exactly to perform a proper cupping:

1. Measure Coffee: Place roughly 10 grams of freshly roasted and immediately ground coffee into a cupping bowl. Grind size should be similar to coarse sea salt.
2. Smell the Dry Aroma: Before adding water, take a moment to evaluate the dry coffee’s fragrance. This gives you the first clue about its origin and processing.
3. Pour Hot Water: Heat water to around 95°C (do not use boiling water). Pour approximately 90–100ml over the grounds. Let it sit for about 30 seconds to allow the coffee to bloom.
4. Smell the Wet Aroma: As steam rises after pouring, lean in and take in the intense aromas released during the bloom phase.
5. Steep: Allow the coffee to steep for 3–5 minutes. Do not disturb it during this time.
6. Break the Crust: After steeping, use a spoon to break the crust of coffee grounds that has formed on the surface. Do this gently but thoroughly, keeping your nose close to catch the rising aromas.
7. Skim the Floaters: Remove any remaining coffee grounds or foam from the surface using the back of the spoon.
8. Taste by Slurping: Using a spoon, take a spoonful of the brewed coffee—avoiding grounds—and aspirate it forcefully into your mouth so it covers your entire palate. Focus on texture, flavor, and how the coffee moves across your tongue.
9. Evaluate Mouthfeel & Flavor: Pay attention to the body, acidity, sweetness, and any specific flavor notes. Let the coffee linger on your tongue before swallowing.
10. Assess Aftertaste: Note how long the flavors last after you spit out (or swallow) the coffee. Good coffees often have a lingering sweetness or complexity.

Key Details You Must Get Right

Throughout the process, specific parameters matter:

• Coffee dose: ~10g per cup
• Water temperature: 95°C (not boiling)
• Steep time: 3–5 minutes
• Grind size: Coarse, similar to table salt
• Tasting method: Slurping to aerate and distribute coffee across the tongue

Frequently Asked Questions

What is the purpose of coffee cupping?

Coffee cupping is used to evaluate the sensory qualities of roasted coffee—aroma, flavor, acidity, body, and aftertaste—without the variables introduced by brewing methods like espresso or pour-over. It’s essential for roasters, buyers, and quality control specialists to assess green bean quality and roast profiles.

Why is 95°C the recommended water temperature for cupping?

95°C is hot enough to extract the full range of coffee compounds without scorching the grounds. Using water that’s too hot (like straight-off-the-boil) can over-extract bitter tannins and ruin the cup, while cooler water under-extracts and dulls flavor.

How much coffee do you use per cupping session?

You use about 10 grams of freshly roasted and ground coffee per cupping bowl. This standard dose ensures consistency across tastings and allows accurate comparison between different coffees.

What grind size is best for cupping?

Cupping requires a coarse grind, similar in texture to sea salt or coarse kosher salt. This grind size balances extraction and prevents over-extraction or excessive sediment during the steeping phase.

How long should coffee steep during cupping?

Coffee should steep for 3 to 5 minutes after pouring hot water over the grounds. This time allows proper extraction without over- or under-developing the coffee’s flavors.

Do you swallow the coffee when cupping?

You can either spit out the coffee or swallow it, depending on the setting. In professional cuppings, many tasters spit to avoid caffeine intake and maintain taste sensitivity. Either way, focus on how long flavors linger after tasting.
