Frequently Asked Questions
What is a good coffee-to-water ratio for French press?
A common range is 1:12 to 1:18 (coffee to water by weight). A ratio around 1:15 is a balanced middle ground, while 1:12 is strong and 1:18 is milder.
Should I measure coffee by weight or volume?
Weight (grams) is more accurate and consistent than volume measurements like tablespoons, since coffee bean density varies.
How much water is in one cup for coffee brewing?
Coffee brewing typically uses an 8 fluid ounce 'cup', which is different from a standard 12oz mug — this calculator uses the standard 8oz brewing cup.
