How did your last shot taste?
Tap a taste. This is the advice CoffeeLabZ gives you.
A bit sour, strength just right
Tastes sour: grind finer, 1 number (to 14).
Change one thing at a time.
Example: Espresso on a Niche Zero, grind 15, 18 g in, 36 g out, 26 s.

Questions, answered
What is CoffeeLabZ?
A free coffee notebook that helps you dial in your grinder for every bag of beans and every brew method. Log a brew, say how it tasted, and CoffeeLabZ tells you the one thing to change next.
How does it know what to change?
Tap the taste compass: sour, bitter, weak or strong. CoffeeLabZ turns that into one next step, like “grind 2 clicks finer” or “use a little more coffee”, in your own grinder’s numbers.
Which grinders and brewers does it support?
More than 1,100 grinders, espresso machines, brewers, kettles and scales, and you can add your own. It covers espresso, pour over, drip machines, French press, AeroPress, moka pot, cold brew, Turkish coffee, siphon and Vietnamese phin.
Do I need an account?
No. Everything works offline on your device. Signing in is optional and only needed to sync between devices or share recipes with a crew.
Is CoffeeLabZ free?
Yes. The app is free and shows one small banner ad that is not personalized. The tutorials and the gear guide on this site are free too.
Does CoffeeLabZ track me?
No. There are no analytics and no tracking. Your notebook stays on your device, and you can download or delete all of it at any time.
Which languages does it speak?
Fifteen: English, Hebrew, Arabic, Bengali, German, Spanish, French, Hindi, Indonesian, Italian, Japanese, Polish, Portuguese, Russian and Chinese.
I’m new to this. Where do I start?
Pick your brew method in the tutorials. Each one gives you a starting recipe, the common mistakes and quick fixes, in plain words.
Your next cup, one click better.
