How to Cup Coffee at Home: The Pro Tasting Method, Simplified

The fix: 11g medium-coarse per bowl, 200ml just-off-boil water, break the crust at 4 minutes, skim, then slurp-compare between bowls as they cool. Identical treatment = honest comparison.

Cupping is the tasting protocol the entire coffee industry uses to evaluate beans — the method behind every score, every green-coffee purchase, every "92 points" on a fancy bag. It survives unchanged because it solves one problem perfectly: it removes brewing skill from the equation. No pour technique, no machine, no filter choice — just ground coffee, hot water, and time, identical for every coffee on the table. Which makes it the fairest possible way to answer the home questions that matter: which of these two bags do I actually prefer? Did this coffee change since last month? What does "washed vs natural" really taste like?

And it needs equipment you already own.

#What you need

• 2 or more identical bowls or sturdy cups (~200ml capacity) — identical matters; the comparison is the point
• A soup spoon (rounded, deepish)
• Kettle, scale, timer, and a grinder
• Two or more coffees to compare (cupping one coffee alone works but wastes the method's superpower)
• A glass of warm water for rinsing the spoon between coffees

#The protocol (simplified SCA)

1. Grind 11g per bowl, medium-coarse (a bit coarser than pour-over), grinding a small purge dose first so one coffee doesn't contaminate the next. Smell each bowl of dry grounds — note one word.
2. Pour 200ml of just-off-boil water (~95°C) into each bowl, timer running, soaking all grounds. That's roughly 1:18; precision matters less than identical treatment across bowls.
3. Wait 4 minutes. A crust of grounds floats on each bowl. Don't touch.
4. Break the crust at 4:00: push the crust back gently three times with the spoon while putting your nose right at the bowl. This aroma burst is the single most expressive moment in cupping — it's where coffees differ most loudly. One word per bowl.
5. Skim: with two spoons, lift off the floating foam and grounds. Rinse spoons.
6. Wait ~5–6 more minutes. Cupping is tasted warm, not hot — flavor opens as it cools.
7. Slurp: spoonful, then a sharp, noisy slurp that sprays the coffee across your whole palate. (The violence is functional — aerosolizing aromatics to your retronasal smell. Commit to the noise.) Move between bowls constantly: A, B, A, B. Rinse the spoon between coffees.
8. Re-taste as they cool over the next 10–15 minutes. Cool coffee hides nothing — sweetness, sourness, and defects all step forward. Many verdicts flip at the cool stage; it's the most honest read.

#What to evaluate (keep it to five)

Score each 1–5 if you like numbers, or just write a phrase. The deliverable is a comparison: "A is brighter and cleaner; B is heavier with a cocoa finish; I prefer B in the morning."

#Three sessions worth running

1. The new-bag referendum: new coffee vs your current favorite. Settles "is this roaster worth it" in 30 minutes.
2. The processing lesson: a washed vs a natural from the same origin — the most vivid taste-education single session available.
3. The freshness check: same coffee, fresh bag vs 6-week-old bag. You will never skip roast dates again.

#Honest caveats

Cupping shows the coffee's character, not how it will taste as espresso or pour-over (immersion at 1:18 flatters some coffees, mutes others). The 11g/200ml/4-minute numbers are conventions — consistency across bowls beats hitting any exact figure. And your first session will feel theatrical; by the second one, breaking the crust will feel like opening a present. Log each session's notes — a cupping log becomes your personal map of what you like, which is the most useful document in your coffee life.
