Figuring out how much coffee to buy at once doesn't have to be a guessing game or feel like math homework. (But, shout out to all the math teachers out there who we’re sure wouldn’t assign any more homework than what’s necessary. ) We crunched the numbers so you don't have to. We based these estimates assuming one 12-ounce cup of coffee per person per day using a 25 gram dose — what we recommend for most brewing methods. (Not sure how much coffee to use for your preferred method? Take a peek at our brewing guides.)

Use this handy little chart below to help you procure the perfect portion of coffee (or, hopefully, at least get close)!
