Coffee Brew Ratio Calculator
Pick a brew method and enter your water, coffee, or cup count. The page gives the matching dose, scales batches, and walks cold brew from concentrate to finished cups.
How it works
Behind the numbers
Pick how you want to work: from a known water amount, a known coffee dose, a cup count, or a cold brew batch. Method presets set the ratio, and the strength control nudges it 15% either way without changing the method.
Batch mode multiplies your cup count by cup size, so office coffee for twelve stays in ratio. The comparison table shows what the same dose brews as across every other method, useful when switching between French press and pour over.
Cold brew gets its own chain: dose to concentrate water, minus absorption, then your dilution ratio to finished servings. Each method also lists grind size and brew time as starting guidance.
FAQ
Questions, answered
What is the best coffee to water ratio?
1:16 is the standard starting point for pour over, drip, and Chemex; French press runs 1:14, AeroPress 1:13, moka pot 1:10, and espresso 1:2. Cold brew concentrate starts at 1:5 before dilution. Adjust stronger or weaker to taste.
How much coffee do I need for 4 cups?
Four 8 oz cups is about 950 ml of water, which needs roughly 60 g of coffee at 1:16. The batch mode scales any cup count and keeps the ratio exact.
How do you dilute cold brew concentrate?
Start around 1 part concentrate to 1 part water or milk, then adjust. The calculator first figures your concentrate yield (grounds absorb about twice their weight in water), then converts your dilution ratio into finished servings.
How many grams of coffee per cup?
About 15 g per 8 oz cup at 1:16. Stronger drinkers land near 17-18 g. Weighing beats scoops: a tablespoon of coffee can vary by several grams with grind and roast.
