Common questions
Are these brew calculators free?
Yes. Every tool is free, runs in your browser, and needs no signup or account. Set your inputs and read the result.
What coffee-to-water ratio is best?
1:16 is the standard starting point for pour over and drip. French press runs richer at 1:12 to 1:15, cold brew is brewed strong at 1:8 then diluted, and espresso is measured as dose to yield, usually 1:2. Use the matching calculator to dial it in.
Do I need a scale?
Yes, a cheap kitchen scale is the single best upgrade for consistent coffee. Scoops vary by several grams depending on grind, which swings the ratio enough to change the taste.
