The way professionals taste coffee — a simple, repeatable ritual with a bowl and a spoon that teaches your palate faster than anything else.

Cupping is how the coffee trade tastes coffee, and it is far simpler than it sounds. Everyone grinds the same, pours the same water and waits the same four minutes, so the only thing that differs from bowl to bowl is the coffee itself. That makes it the fairest way there is to compare beans, check a new bag, or simply train your palate — and because there is no pour technique or filter to get wrong, it is also the most forgiving way to brew. You grind, you smell, you pour, you break the crust, and you slurp. This guide explains why it works, what you need, the protocol step by step, and how to name what you taste.
01 — The point
Why cup at all
Cupping exists to take the brewing out of the equation. When every bowl is made with the same grind, ratio, water and time, the method can no longer flatter one coffee or spoil another, so any difference you taste comes from the beans alone. That is exactly what you want when you are comparing two coffees side by side, deciding whether a new bag is any good, or trying to work out what you actually like.
Professionals use the ritual to score coffee formally, judging it out of a hundred points on aroma, flavour, acidity, body and more. At home you do not need the scoresheet; the same few bowls will sharpen your palate quicker than months of ordinary brewing, and once you have cupped a handful of coffees against each other you will never taste your morning cup quite the same way again.
02 — The kit
What you need
Cupping needs almost nothing you do not already have:
- Identical bowls or cups, around 200–250 ml, one or more per coffee. Matching vessels matter more than fancy ones, because you are comparing.
- A deep, round spoon — a proper cupping spoon if you have one, or a soup spoon.
- A scale, a kettle and a burr grinder, so every bowl is weighed and ground the same.
- Two to four coffees to compare — the whole point is to taste them against each other.
- A glass of clean water to rinse the spoon between bowls.
Those are the official numbers, but the ratio is what matters: keep it at roughly one part coffee to eighteen parts water and scale to whatever bowls you own. Grind a touch coarser than you would for filter, so the crust forms nicely and the grounds settle.
03 — The ritual
The cupping, step by step
The whole session takes about fifteen minutes and follows the same unhurried order every time.
- Weigh coffee into each bowl and grind it fresh, one bowl at a time so nothing carries over from the last.
- Smell the dry grounds — the fragrance — and jot down your first impression before any water goes in.
- Pour water just off the boil over the grounds, to the same level in every bowl, wetting all of it, and start a four-minute timer. A crust of grounds will float to the top.
- At four minutes, break the crust: push your spoon gently through the top and lean in to smell the aroma that releases. It is the best smell of the whole session.
- Skim the floating grounds and foam off the surface with two spoons, and discard them.
- Once it has cooled to warm, taste by slurping a spoonful sharply off the spoon so it sprays across your whole mouth. It sounds absurd, but aerating it that way spreads the coffee over your palate.
- Taste each coffee again as it cools, rinsing the spoon between bowls. Flavours shift with temperature, and the sweetness and fruit often show up best once it is nearly cold.
04 — The vocabulary
What to taste for
As you taste, you are really judging a handful of qualities. Fragrance and aroma are how it smells, dry and then wet. Flavour is the main taste in the middle of the sip. Acidity is the brightness or liveliness that makes a coffee sparkle — welcome when it is juicy and sweet, a fault when it turns sharp and sour. Body is the weight and texture in your mouth, from tea-like to syrupy. Sweetness, aftertaste and overall balance round it out. Naming the specific notes is where the flavour wheel comes in.
The flavour wheel
Nine families, each opening onto specific notes
Use it from the inside out. Start broad — is this coffee fruity, or nutty, or floral? — then follow that wedge outward to something more exact, from fruity to berry, or from nutty to almond. You do not need to be right; you need to be consistent, building your own map of what each word tastes like. The two tables below give you the attributes to judge and the questions to ask yourself as you go.
| Attribute | What it means |
| Aroma | How it smells — dry as fragrance, then wet after the crust is broken. |
| Flavour | The main taste in the middle of the sip. |
| Acidity | Brightness and liveliness — good when juicy, a fault when sharp and sour. |
| Body | Weight and texture in the mouth, from light and tea-like to heavy and syrupy. |
| Sweetness | Roundness and the absence of harshness, like ripe fruit. |
| Aftertaste | What lingers once you have swallowed, and for how long. |
A simple home scorecard
You do not need the professional hundred-point sheet. A few honest questions, asked the same way every time, will build your palate just as well — write the answers down, because comparing your notes later is where it all clicks.
| Note | Ask yourself |
| Aroma | What does it smell of — fruit, flowers, chocolate, nuts? |
| Acidity | Bright and juicy, or sharp and sour? |
| Body | Light and tea-like, or heavy and full? |
| Flavour | What notes can you name, using the wheel? |
| Finish | Clean and long, or short and dull? |
| Overall | Would you happily drink a whole cup? |
Cup a few coffees side by side just once and your palate will take a leap that no amount of ordinary brewing can match. It is the single best thing you can do to understand what you like and why. Line up a flight of our single origins below, and taste them against each other — the differences will be plain in the bowl.
