The ratio of ground coffee to water differs greatly between brew methods and personal taste. The ratios on this page are based on a mixture of consensus and official sources.
But, there is no right way—so long as you enjoy your coffee and aren't consuming a dangerous amount!
The ratio of 1:6 is taken from the original recipe by Alan Adler; inventor of the Aeropress. This brew ratio results in a concentrate, much like an espresso—you can add hot water or milk to your liking.
Although there is no original or definitive coffee to water ratio for a french press, 1:12 seems to be a popular choice. We derived this from a recipe for a 17oz (500g) capacity french press.
Hario, the makers of the v60, recommend a ratio of 3:50
—15g of coffee to 250g of water for one full mug.
Chemex recommends you “put one rounded tablespoon of coffee per 5 oz cup into the filter cone.” This is roughly a 1:10 ratio, but most people agree that's too strong. Many winning baristas have used a ratio between 1:13 to 1:17.
We derived the ratio of 1:10 from a Bialetti Junior Moka Pot, which has a 200ml water capacity. This serves about 2 small cups of delicious coffee.
There are many ways to make cold brew coffee. This recipe uses a Filtron, a reliable method of making a smooth cold brew. This results in a concentrate that you can dilute to your tastes.
