Matcha Sample Scorecard: Criteria You Can Copy
A matcha scorecard is only useful if every taster reads the scale the same way. Score each coded sample on four blocks (dry powder, straight, in milk and workflow) using a 1–5 scale with written descriptors, and fill it in before anyone discusses the cups. Copy the table below into a document or spreadsheet. It is designed to go with the step-by-step sample testing protocol, which covers preparation and controls.
How to use the scorecard
- One sheet per taster. Collect sheets before discussion.
- Code the cups (A, B, C). The person preparing the cups does not score.
- Score what you observe, not what you expect. If a criterion does not apply to your decision (for example, straight tasting for a latte-only menu), mark it "n/a" rather than guessing.
- Write one note per score below 3. A low score without a reason cannot be acted on.
The 1–5 scale
Use these general definitions for every criterion, plus the specific descriptors in the scorecard.
| Score | Meaning |
|---|---|
| 1 | Unacceptable: a clear fault you would not serve |
| 2 | Weak: noticeable problem, would need a recipe change |
| 3 | Acceptable: does the job, nothing stands out |
| 4 | Good: clearly meets what you want |
| 5 | Excellent: best in the set, and you would choose it for this reason |

Taster: __ Date: __ Recipe used (dose, water, milk, cup): __
| Block | Criterion | What a 1 looks like | What a 5 looks like | A | B | C |
|---|---|---|---|---|---|---|
| Dry powder | Colour (side by side) | Dull, yellowish or brownish next to the others | Brightest, most vivid green in the set | |||
| Dry powder | Texture | Gritty, coarse or hard clumps that do not break | Fine and soft, clumps break under light pressure | |||
| Dry powder | Aroma | Flat, stale or off smell | Fresh, clear vegetal or sweet aroma | |||
| Straight | Bitterness | Harsh, dominant bitterness | Little or no bitterness; balanced | |||
| Straight | Astringency | Strongly drying, rough on the tongue | Smooth, little drying | |||
| Straight | Savoury depth and sweetness | Thin, watery, no depth | Full, rounded, savoury-sweet | |||
| Straight | Finish | Short or unpleasant aftertaste | Clean, pleasant, lingering | |||
| In milk | Matcha flavour through milk | Tastes mainly of milk | Clear matcha flavour throughout the drink | |||
| In milk | Balance with milk | Bitter or grassy edge stands out | Integrated, no harsh edge | |||
| In milk | Colour in cup after 5 min | Grey or dull green | Still clearly green | |||
| In milk | Mouthfeel and last sip | Grit or sediment in the last sip | Smooth to the last sip | |||
| Workflow | Mixes without lumps | Lumps remain after normal mixing | Smooth paste in normal mixing time | |||
| Workflow | Repeatability | Cups vary noticeably at the same dose | Consistent cup to cup | |||
| Workflow | Sieving and handling | Clogs sieve, static, messy | Passes the sieve easily, clean to handle | |||
| Block totals and notes |
Notes on any score below 3:
- A: __
- B: __
- C: __
Overall preference (rank 1st, 2nd, 3rd): A __ B __ C __
Optional weighting
Raw totals treat every line equally. If your decision is mainly about lattes, weight the blocks. The weights below are examples to adjust to your menu; they should add up to 100.
| Block | Lines | Example weight: latte menu | Example weight: pure serve |
|---|---|---|---|
| Dry powder | 3 | 10 | 15 |
| Straight | 4 | 15 | 55 |
| In milk | 4 | 55 | 0 |
| Workflow | 3 | 20 | 30 |
To apply weights fairly when blocks have different numbers of lines, use the block average:
Weighted score = Σ (block average × block weight)
Example: a sample averaging 4.0 in dry powder, 3.5 straight, 4.25 in milk and 4.0 in workflow, with the latte weights:
(4.0 × 10) + (3.5 × 15) + (4.25 × 55) + (4.0 × 20) = 40 + 52.5 + 233.75 + 80 = 406.25 out of a maximum of 500.
These scores are an illustration of the arithmetic, not results for any product.
Reading the results
- Average across tasters, then compare samples. With two to four tasters, look at each sheet as well as the average; one strong objection can matter more than a small average gap.
- Check the knock-outs first. Any 1 on a criterion you care about (grit, colour in milk) should normally rule a sample out, whatever its total.
- Compare against your criteria. Scores rank samples; acceptance criteria decide whether you order. Setting acceptance criteria for a 1 kg order shows how to fix thresholds such as "no score below 3 in milk" before you taste.
If tasters use different words for the same thing, align on vocabulary before the next session. Umami, astringency and sweetness gives shared terms.
Tips for cleaner scores
- Taste in the same order on every sheet, but rotate the cup order between tasters if you can.
- Rinse with water between cups.
- Plan the grams for every scored cup before you open a sample; how many test drinks a 10 g sample makes shows how to keep a reserve for a retest.
- Score the latte twice, at about two minutes and at five minutes, if colour or settling matters to you; note both.
- Keep completed sheets with the date and recipe. They become your reference for checking later deliveries.
