A good coffee tasting with friends needs only three contrasting coffees, one repeatable brewing method, small servings and a few minutes of quiet note-taking before anyone compares opinions. Keep dose, water, grind, temperature and cups as consistent as possible. That way the group mostly compares coffee rather than brewing accidents.
Professional assessment is more formal. The Specialty Coffee Association's current Coffee Value Assessment distinguishes objective description, personal or market preference and information outside the cup. A home evening can borrow that useful distinction without becoming an exam.
The easiest first format #
| Format | Why choose it | Trade-off |
|---|---|---|
| Three coffees, same brewer | Clearest beginner comparison | Shows less about brewing methods |
| Home cupping | Efficient and close to a tasting workshop | Requires equal bowls and spoons |
| One coffee, three brewers | Reveals extraction differences | More equipment and coordination |
| Blind-labelled cups | Reduces price and brand bias | Someone must prepare the codes |
Plan roughly an hour for four to six people. For a more instructional session, use the fuller coffee tasting workshop plan.
How much coffee to buy #
Three coffees are enough. Allow roughly 20 to 30 g of each for small cupping or filter portions for four to six people, with extra if you want to brew a favourite again. Four or five samples work for experienced tasters, but more quickly causes fatigue.
Choose real contrasts rather than relying on country stereotypes:
- washed and natural processing;
- light and medium roast;
- floral or fruit-led and chocolate or nut-led profiles;
- an Arabica and a blend containing Robusta;
- a local Swiss roast and a mainstream coffee;
- regular and decaf for an evening session.
Origin never guarantees a taste. Variety, processing, roast, freshness and extraction also matter. Pick bags that state enough detail to discuss after the reveal.
A practical equipment list #
- burr grinder and gram scale;
- kettle and pleasant-tasting water;
- one stable filter brewer, French press or identical cupping vessels;
- matching cups or glasses;
- clean spoon for each participant if cupping;
- plain water and neutral bread or crackers;
- paper, pencils and labels A, B and C.
If grinds differ markedly, the result may reflect extraction more than the beans. Our grind-size guide gives sensible starting points.
Two simple brewing options #
For home cupping, use equal cups with 8 to 10 g coffee per 150 ml water. Add the same water to each, steep for the same time, break and remove the crust, then taste small spoonfuls as the coffee cools. Use a clean-spoon system and do not share a tasting spoon directly between mouths and bowls.
For filter coffee, use one recipe for every sample, such as 12 g coffee per 200 g water. Prepare in the same order and serve in coded identical cups. Do not compare three coffees made with three different brewers unless method is the subject.
A relaxed one-hour running order #
- Introduce the exercise without showing price or brand.
- Smell the freshly ground samples.
- Brew with one consistent recipe.
- Taste first while warm and again while cooler.
- Ask everyone to write three words privately.
- Discuss aroma, acidity, sweetness, bitterness, body and finish.
- Reveal the bags and compare expectation with experience.
- Rebrew the favourite as a full cup if the group wants one.
The first silent notes matter. A confident suggestion such as strawberry can influence what everyone else starts looking for.
Use ordinary sensory language #
Ask which cup is brighter, rounder, more bitter, lighter, silkier or longer-lasting. Cocoa, toast, citrus, flowers and nuts are useful descriptions. They do not claim that those ingredients were added. The World Coffee Research Sensory Lexicon can supply reference words, but it should not become a compulsory checklist.
Separate two statements: "this coffee is bright and light-bodied" describes it; "I prefer the rounder cup" expresses liking. Both are legitimate.
Food, portions and caffeine #
Serve water during the comparison and strongly flavoured food afterwards. Chocolate, cheese, spices and sweet cake can mask subtle differences. Once the notes are complete, pair coffee with plain cake, dark chocolate, nuts or milk foam and acknowledge that the subject has shifted to food pairing.
Small tastings also control caffeine. The EFSA gives 400 mg per day as a level that does not raise concerns for most healthy adults, but actual coffee varies and individual sensitivity can be much lower. Offer decaf, avoid late scheduling and never pressure a guest to finish every cup.
Mistakes that blur the comparison #
- Buying too many coffees.
- Changing several brewing variables at once.
- Serving full mugs of every sample.
- Showing price and tasting notes before the first sip.
- Using very stale pre-ground coffee.
- insisting that one participant has found the correct flavour.
- making espresso the first format for guests unused to intense coffee.
The best outcome is not a unanimous winner. It is a group that can say more clearly why two cups feel different and which one each person would choose again.
