How it works

1

Describe your taste.

Too bitter, sour, weak, or flat — just pick what you noticed. No technical knowledge required. Plain language only.

2

Coach diagnoses your brew.

Coffee Brew Coach cross-references your tasting notes against your brew method, dose, grind, and extraction time to pinpoint the problem.

3

Get one specific fix.

Not a list of possibilities — one targeted change to make on your next brew. Grind finer. Drop the dose 0.5 g. Shorten your steep by 15 seconds.
