Espresso Ratio Calculator

Set your dose, pick a ratio, get the right yield and brew time. Plus what to change when it tastes wrong.

How to dial in

Set dose first, then pull and time. Adjust grind to hit time target.
Sour / acidic / under-extracted → grind finer.
Bitter / dry / harsh → grind coarser.
Light roasts generally want longer ratios (1:2.5–1:3) and longer time.
Always weigh both dose and yield. "By volume" is unreliable.
