Do I need special equipment to cup coffee at home?

Matching bowls, a scale, and a kettle — that's the minimum. Any bowl that holds 200ml and allows you to stir works. A kitchen thermometer helps with water temperature. A cupping spoon helps with slurping technique but isn't required. The protocol matters more than the equipment.

What does 'slurping' do that normal sipping doesn't?

Slurping aggressively sprays coffee as a fine mist across the full surface of the palate, coating taste receptors that a normal sip wouldn't reach. It also aerates the coffee, volatilizing aroma compounds that reach retronasal olfactory receptors. Most of what we call 'taste' is actually smell — slurping maximizes aroma compound delivery.

How many coffees should I compare in a home cupping?

3–6 is the practical home range. Fewer than 3 gives you limited comparison context. More than 8 causes palate fatigue and makes later coffees harder to evaluate fairly. For comparing your own roast profiles, 3–4 variations of the same green lot (different roast degrees or development times) is the most productive setup.

What Cupping Is and Why to Do It

Cupping is the coffee industry's standard evaluation method — used by Q graders, roasters, and buyers worldwide. The protocol eliminates brewing variables (no filter, no pressure, no pouring technique) so that the coffee itself is what you're evaluating. At home, cupping lets you compare coffees side by side with identical preparation, identify flavor differences objectively, and evaluate your own roasts against a standard baseline.

The SCA Protocol (Simplified for Home)

Equipment: 3–6 matching bowls (200–250ml), a scale, a kettle, a cupping spoon, and 3–6 different coffees. A timer.

Ratio: 8.25g coffee per 150ml water. For home: round to 8g per 150ml for simplicity. Weigh everything.

Grind: Medium to medium-coarse — coarser than pour-over, finer than French press. All coffees ground at the same setting.

Process:

1. Add ground coffee to each dry bowl. Note the dry fragrance — some of the clearest flavor impressions come before water is added.

2. Start a timer. Pour 150ml of water at 200°F (93°C) simultaneously into each bowl, saturating all grounds.

3. At 4 minutes, break the crust: push a spoon through the floating grounds layer on each bowl from back to front. Put your nose close as the crust breaks — the released aroma is the most concentrated flavor signal in the cupping. Note what you smell.

4. Remove the floating grounds from each bowl using two spoons.

5. Wait 5 more minutes. The coffee cools to a safe tasting temperature.

6. Taste by slurping a spoonful aggressively — spraying the coffee across your entire palate. Evaluate: acidity (brightness/tartness), sweetness, body (weight in the mouth), flavor (specific notes), and finish (how long pleasant flavors linger).

7. Continue tasting as the coffee cools — different flavors emerge at different temperatures. Complexity shows itself most clearly around 130–140°F.

☕ Key Takeaway

8g per 150ml, medium-coarse grind, 200°F water, 4-minute steep, break the crust, remove grounds, taste at multiple temperatures. The aroma at crust break and the flavor at 130–140°F are the most informative moments in a cupping.
