Enter coffee grams and brew ratio (1:X) to get the water you need — pour over, French press, drip or espresso.
| Input | Result |
|---|---|
| 30 g at 1:16 | 480 g water |
| 20 g at 1:15 | 300 g water |
| 60 g/L (1:16.7) | SCA golden cup midpoint |
Start at 1:16 (e.g. 30 g coffee to 480 g water) for pour over and drip. 1:15 tastes stronger, 1:17–1:18 lighter. The SCA golden-cup window is 1:15–1:18.
Yes — espresso 1:2, moka pot 1:10, French press 1:14–1:16, pour over 1:15–1:18, cold brew concentrate 1:5–1:8.
A tablespoon of coffee varies 3–5 g depending on grind and bean density; grams make the ratio repeatable. Use any kitchen scale.
