What is Coffee Brew Ratio Calculator?
The Coffee Brew Ratio Calculator turns a dose and a water ratio into the exact recipe for six common brewing methods: pour-over, espresso, French press, cold brew, moka pot and drip machine. It scales the recipe by cup count, splits the bloom water at twice the dose where the method uses one, and labels the strength of any ratio from strong through light so you can steer the cup before wasting beans.
Key Benefits
- Exact water and dose for every method, no more guessing grams
- Typical ratio ranges per method so presets start sensible
- Bloom water split included where the method calls for it
- Strength guide to steer taste before brewing
- Multi-cup scaling for the whole carafe in one field
Common Use Cases
- •Dialing in a new bag of beans on a V60 or Chemex
- •Pulling consistent espresso shots at 1:2 or 1:3
- •Batching cold brew concentrate for the week
- •Serving coffee to guests without mental arithmetic
- •Comparing how the same beans taste at different strengths
How to Dial in a Coffee Recipe
- Pick the brew method: Choose pour-over, espresso, French press, cold brew, moka pot or drip. Each method sets its typical ratio range and bloom convention.
- Enter dose and ratio: Type the coffee dose per cup and the water ratio. A 1:16 pour-over means 15 grams of coffee to 240 grams of water; 1:2 espresso means 18 grams in, 36 grams out.
- Scale and brew: Set the number of cups to scale the whole recipe, check the bloom water pour, then brew to the method time.
