Taste Log Fields That Make Shots Comparable

Start with the recipe block

Taste notes are meaningless without context. Record these before tasting:

• Coffee name and roast date.
• Dose, yield, ratio, and time.
• Grind setting and any change from the last shot.
• Basket and machine, if you use more than one.
• Water source, if you change it.

These fields do not change every day, but they explain the taste when it does change.

The five taste fields

Keep the vocabulary small enough that you will actually use it.

1. Sweetness

Rate it on a simple scale, for example none, low, medium, high. Sweetness is one of the clearest signs that extraction is in a good place. It is also easy to imagine, so anchor it: compare against a known sweet shot rather than rating in isolation.

2. Acidity

Rate intensity, not quality. "High acidity" can be pleasant or unpleasant; the rating should describe how much brightness you perceive. Add a separate note for whether it reads as fruit, citrus, or sharp.

3. Body

Thin, medium, or full. Body is about texture and weight, not flavour. A shot can be full-bodied and still taste sharp.

4. Finish

What remains after you swallow: clean, dry, bitter, sweet, lingering. Finish is often where over-extraction shows up, so give it its own field rather than folding it into "aftertaste."

5. Defects

Name them plainly: harsh, ashy, salty, hollow, papery, rubbery. A defect field stops you from writing "not great" and forces a direction for the next shot.

Optional fields that earn their place

• Balance: which attribute dominates. "Acidity-forward," "sweetness-forward," "bitter finish."
• Intensity: weak, medium, strong. Useful when comparing ratios.
• Temperature when tasted: hot, warm, cool. Coffee changes as it cools; note when you tasted it.
• With milk: if you drink milk drinks, a separate note because the balance shifts.

Do not add ten fields you will skip. Four or five used consistently beat fifteen used occasionally.

Scales and consistency

Pick a scale and stay on it. For example:

The numbers are not measurements. They are anchors that keep your ratings comparable across weeks. If you switch from a 1–5 scale to a 1–10 scale, the old rows become hard to read.

Write the note before you adjust

Taste the shot, write the note, then decide what to change. If you adjust first and taste after, you are tasting a different shot and the note belongs to neither.

Also taste at a consistent moment. The first sip, a sip after thirty seconds, and the last cool sip can differ. Pick one primary moment, usually while warm, and note if you also tasted later.

Avoid borrowed language

Wine-style flavour lists are tempting, but they can push you to taste things that are not there. Start with the five fields above. If a specific note is unmistakable, add it as a short free-text comment, not as a required field. "Blackcurrant" is useful if you actually taste it; it is noise if you added it because the bag said so.

Do not copy the roaster's tasting notes into your log before tasting. Write your own first, then compare.

A filled example

The rows are comparable because the fields are the same and the change is explicit.

Reviewing the log

Once a week, read the last ten rows. Look for patterns:

• Do shots with a certain time range taste sweeter?
• Does a particular defect appear after a dose change?
• Are you consistently rating acidity high with one coffee?

The log is a tool for finding patterns, not a diary. If you never read it, the fields do not matter.

Bottom line

Record the recipe, then five taste fields: sweetness, acidity, body, finish, and defects. Use the same scales every time, taste before adjusting, and write your own notes before reading the bag. Consistency in the fields is what makes the log comparable.
