Cupping at Home: How to Taste Coffee Like a Pro
What Cupping Is
Cupping is how coffee professionals taste. Importers, roasters and graders use it to compare dozens of coffees, decide what to buy and give the scores you see on some bags (80 points and up counts as “specialty”). It is also the simplest, fairest way to compare two or three bags at home.
The idea is to remove the brewer from the equation. Every coffee gets the same dose, the same grind, the same water and the same steeping time in an identical cup. Any difference you taste comes from the beans, not from your technique.
The Protocol, Simplified
The numbers below come from the SCA’s long-standing cupping protocol, which professionals have used for years. The SCA published an updated standard in 2024 with slightly looser tolerances, but the core recipe is the same.
| Professional standard | At home | |
|---|---|---|
| Coffee | 8.25 g per 150 ml of water (about 1:18) | 13 g for an 8 oz (240 ml) cup |
| Grind | Slightly coarser than drip (70–75% passes a #20 sieve) | Medium-coarse, between drip and French press |
| When to grind | No more than 15 minutes before adding water | Right before you start |
| Water | 200 °F (93 °C), give or take 2 °F | Just off the boil: let it sit 30 seconds |
| Cups per coffee | 5 | 1–2 |
| Break the crust | 3–5 minutes (many labs use 4) | 4 minutes |
| Start tasting | After about 10–15 minutes | When you can sip without burning |
Professionals weigh whole beans, then grind each cup separately so one bad bean cannot spoil a whole sample. At home, grinding enough for one cup at a time works fine.
What You Need
- 2–3 coffees to compare, roasted at least a day or two ago
- Identical cups, one or two per coffee: rocks glasses, small bowls or matching mugs, 6–9 oz (180–270 ml)
- A burr grinder and a scale that reads in grams
- A kettle, ideally with a thermometer
- Soup spoons, ideally round and deep, and a cup of hot water to rinse them
- A spit cup if you will taste a lot
- Paper and a pen, and sticky notes to label the cups underneath
Step by Step
- Weigh and grind. Weigh 13 g of each coffee and grind it into its own cup. Grind a few beans of the next coffee first to flush the previous one out of the grinder.
- Smell the dry grounds (fragrance). Lift each cup to your nose and note what you smell. This is where florals and fruit are often strongest.
- Pour. Start a timer and fill each cup to the brim with 200 °F (93 °C) water, wetting all the grounds. Fill them in the same order you will break them.
- Wait 4 minutes. A crust of grounds forms on top. Do not stir.
- Break the crust. At 4:00, put your nose close to the cup and push the crust back with the spoon, stirring gently about three times. A burst of aroma comes up; this is the best smell of the session. Rinse the spoon between cups.
- Skim. Use two spoons to lift off the foam and floating grounds. Most of the grounds sink.
- Let it cool. Wait about 10 minutes until the coffee is hot but sippable.
- Slurp. Take a spoonful and slurp it hard and loud, like slurping soup. Spraying the coffee across your mouth with air carries the aroma to your nose. Swallow or spit.
- Taste again as it cools. Go from cup to cup, then come back a few minutes later. Coffees change a lot between hot and warm, and flaws often show up as they cool.
Tip: Label the cups on the bottom and shuffle them before you taste. Tasting “blind” stops you from finding the notes printed on the bag just because you read them.
A Three-Coffee Session
For your first cupping, pick coffees that are clearly different, so you learn what to listen for.
| Cup | Try | What to look for |
|---|---|---|
| A | A washed Ethiopian , light roast | Floral, tea-like, citrus acidity, light body |
| B | A natural from Ethiopia or Brazil | Berry or chocolate, more sweetness and body |
| C | A medium or dark roast from your usual grocery or café | Roasted, nutty, cocoa; less acidity |
For each cup, write a few words for fragrance (dry), aroma (at the break), flavor, acidity, sweetness, body and aftertaste. The flavor wheel guide has the vocabulary. Then rank the three: which would you buy again?
Once you can tell very different coffees apart, make it harder: two washed coffees from different countries, or the same coffee at two roast levels. A side-by-side of washed and natural processing is one of the most eye-opening lessons there is.
Common Mistakes
- Different doses or cups: the comparison only works if every cup is the same.
- Tasting too hot: you will taste heat, not flavor. Be patient.
- Grinding too fine: the cups turn muddy and bitter, and the crust will not form properly.
- Stale beans: a freshly roasted bag makes differences much clearer.
Wrap-Up
Cupping is the cheapest tasting class you can take: a few spoons, a scale and three bags of coffee. Do it once a month with new bags, keep your notes, and you will quickly learn which origins, processes and roasts you like best. Then brew the winner your favorite way.
