Coffee to Water Ratio Calculator

The perfect ratio of coffee and water for any brew strength

Step 1: How much coffee do you want to brew?

To brew your french press at full capacity find the french press in the image above the is most similar to yours. As a reference, a standard coffee mug will hold 12 oz fluid ounces.

Once you know the volume of coffee you want to brew, replace the 12 in
"Brewed Coffee = 12" in the calculator below with your number in fluid ounces.

Step 2: How strong do you want your coffee?

Strength is determined by the ratio of coffee to water, increasing the amount of coffee increases the strength. This ratio is often expressed like "1:13" where 1 is coffee and 13 is parts water. The calculator below does this math for you.

Strength settings of 1 to 7 are available.

1 is a 1:10 ratio that will produce bold, thick and heavy flavors

7 is a 1:16 ratio that will produce lighter, subtle and tea like flavors.

Ultimately strength comes down to a matter of personal taste and there is no right or wrong choice. Replace the 4 in "Strength = 4" in the calculator below with your strength setting.
