Coffee to Water Ratio Calculator

Free coffee to water ratio calculator for specialty coffee. Calculate exact grams of coffee and water for V60 pour over (1:16), French press (1:15), Chemex, Aeropress, and cold brew.

How much coffee and water for this brew method?

Specialty coffee in the US is usually described as a ratio, like 1:16 (1 gram coffee to 16 grams water). V60 and drip often sit around 1:16–1:17; French press a bit stronger; cold brew much more concentrated then diluted. This page converts a ratio into grams and tablespoons so you can hit the same cup tomorrow.

Grams beat scoops

A “tablespoon of beans” is not a standard weight. If you care about taste, weigh beans. Tablespoons here are a fallback. Related: cups to grams for kitchen work that is not coffee.

Frequently Asked Questions

What is the golden coffee to water ratio?
The Specialty Coffee Association (SCA) golden ratio is **1:15 to 1:18** (1 gram of ground coffee for every 15 to 18 grams / ml of water). A **1:16 ratio** (approx. 60g coffee per 1 liter of water) is the standard baseline for balanced sweetness, acidity, and body.
How many grams of coffee for a standard 12 oz mug?
A standard 12 oz mug is roughly 355 ml (355 grams) of water. Using the standard 1:16 pour over ratio, you need **22.2 grams of coffee grounds** (about 4 level tablespoons or 2 standard 2-tbsp coffee scoops).
How much coffee for a 4-cup or 8-cup French Press?
French Press uses a richer 1:15 immersion ratio. For a standard 8-cup French press (~1,000 ml water), use **66 to 67 grams of coarse ground coffee**. For a 4-cup press (~500 ml water), use **33 grams of coffee**.
What is the ratio for Cold Brew concentrate?
Cold brew concentrate uses a strong **1:4 to 1:5 ratio** (e.g. 200g coarsely ground coffee to 1,000g water), steeped at room temperature or refrigerated for 16 to 24 hours. When serving, dilute 1:1 with cold water, milk, or ice.
