About this tool
Brew ratio is coffee to water by weight, and it decides whether a cup tastes thin, balanced, or heavy. This calculator works out the missing side: enter coffee to get water, or water to get coffee, for the ratio you choose. A kitchen scale gives the most reliable results.
Frequently asked questions
What ratio suits a pour-over?
Around 1:15 to 1:17 gives a balanced cup. Stronger tastes sit near 1:14, lighter ones near 1:17.
Does water weight equal water volume?
Almost. One gram of water is about one millilitre, so grams and millilitres can be used interchangeably here.
