Coffee-to-water ratio calculator
Enter the dry coffee in grams and the parts of brewing water you want per gram of coffee. For a hot filter brew, the result is the total water to pour, including the bloom.
Worked example
20 grams of coffee at 1:16 takes 320 grams of water. Some stays in the spent grounds, so weigh your finished cup separately when yield matters.
