Frequently Asked Questions
Everything you need to know about coffee ratios
The standard ratio for most brewing methods is 1:15 to 1:18 (coffee to water). This means 1 gram of coffee for every 15-18 grams of water. However, this varies by brewing method and personal taste.
For best results, use a digital kitchen scale that measures in grams. Volume measurements (like tablespoons) are inconsistent because coffee bean density varies. Always measure by weight for precision.
Absolutely! Lighter roasts often benefit from a slightly higher coffee-to-water ratio (like 1:14) to bring out their complex flavors, while darker roasts might taste better with a lower ratio (like 1:17) to avoid bitterness.
Weak coffee usually means too little coffee or too much water (high ratio like 1:20). Bitter coffee often comes from too much coffee or too little water (low ratio like 1:10). Our calculator helps you find the perfect balance.
