How it works
Multiply the weight of the coffee by the ratio to get the weight of water. A ratio of 16 means 16 grams of water for each gram of coffee.
Lower ratios make stronger coffee, and higher ratios make it lighter. Many pour-over brewers land between 15 and 17, though the right number is a matter of taste.
Worked example
With 0.7 oz of coffee at a ratio of 16 to 1, pour 11.2 oz of water.
Questions
Do I need a scale?
A kitchen scale works best, since a scoop changes with how finely the coffee is ground.
What ratio should I start with?
Start near 16, then taste. Add a little more coffee if the cup is thin, or more water if it tastes harsh.
Does this work for espresso?
Espresso uses a much lower ratio, about 1 part coffee to 2 parts water by weight. Enter 2 as the ratio for a rough starting point.
