Overview

The Coffee Ratio Calculator determines the optimal coffee-to-water ratio based on your brewing method — pour-over, espresso, French press, cold brew, AeroPress, and more. Enter either the amount of coffee grounds or desired brew volume, and it automatically calculates the corresponding measurement for a consistently great cup.

Formula

Water (ml) = Coffee (g) x Ratio. Common ratios: Pour-over 1:15-1:17, Espresso 1:2, French press 1:12-1:15, Cold brew 1:5-1:8, AeroPress 1:11-1:14. Example: 20g coffee at 1:16 ratio = 320ml water.

How to Use

1. 1Select your brewing method (pour-over, espresso, French press, etc.).
2. 2Enter coffee grounds weight (g) or desired brew volume (ml).
3. 3Choose your preferred strength (light / medium / strong).
4. 4View the calculated coffee and water amounts.

Tips

• ✔Grind beans just before brewing for the best flavor and aroma.
• ✔For pour-over, water temperature should be 92-96C (197-205F). Water that is too hot causes bitterness.
• ✔Grind size dramatically affects taste — even with the same ratio, finer grinds extract more.
• ✔Cold brew concentrate (1:5) should be diluted 1:1 or 1:2 with water or milk before drinking.
