BREW WATER
480g
30 g coffee × 16 = 480 g water
This is water added to the brewer. The amount in your cup will be lower because coffee and equipment retain water.
Editable starting point, not a universal recipe.
Keep the ritual simple.
Why we weigh coffeeWeigh & brew
Measure coffee and input water from your recipe. The calculator does not set grind, temperature or brew time.
Taste & adjust
Let the cup cool enough to taste comfortably. Change one variable, take a note and make the next cup your own.
This tool is for simple filter and immersion starting ratios. It does not calculate espresso yield, extraction, caffeine, allergy safety or a guaranteed cup quality. Recipe choices remain local to this browser session when storage works.
