How many cups of coffee do you get from a pound of coffee?

There is a general rule that states the higher the coffee-to-water ratio, the fewer cups of coffee you can make per pound of beans. This holds true for espresso, where one ounce is equivalent to eight ounces in terms of how many servings can be made from it. However, because espresso is measured in 1-ounce cups rather than 8-ounce cups, you can make more servings using its name number of beans.

To calculate the amount of coffee you can brew with your beans, start by multiplying the number of ounces of coffee beans you have by the second number in your coffee-to-water ratio. For instance, if you’re using a drip machine and want to brew about 34 cups of coffee, multiply 16 ounces of coffee beans by 1:17 (the recommended water to Coffee bean ratio for drip machines). Then divide that figure—34 cups—by 8 (the amount in an ounce), which results in 3.4 cups per pound.

Brewers who use pour-over methods typically use a 1:17 ratio, though this can be adjusted to taste or according to the brewer’s specific needs. This ratio is the same as that of drip coffee makers, so you can make 34 cups of coffee from a single pound of beans.

Espresso is a high-concentration coffee, so you need a very high coffee to water ratio (1:2) to make it. If you have a pound of coffee beans, you can make about 32 ounces of regular espresso.

French Press

If you’re using a French press, start with a ratio of 1:12 or one part coffee to 12 parts water. With a pound of coffee beans, you can make 150 ounces of coffee. That’s about 19 cups of French press coffee per pound of beans.

Cold Brew

Cold brew concentrate also has a high coffee-to-water ratio (1:5). This means that you can make 80 ounces using a pound of beans, or 10 cups. However, keep in mind that this is concentrated coffee, so you may need to water it down. How much water you add is up to your own taste preferences, but you may be able to make up to 20 cups of cold brew from the pound of beans.
