How long does a 12 oz bag of coffee last?
A 12 oz (340 g) bag holds about 18 cups at an 18 g dose. One cup a day lasts about 19 days, two cups a day about 9.4 days, and three cups a day about 6.3 days.
How many cups of coffee are in a bag?
Divide the bag weight in grams by your dose per cup. At 18 g a cup, an 8 oz bag makes 12 cups, a 12 oz bag 18, and a 1 lb bag 25. A lighter 15 g dose stretches each bag by about a sixth.
How fresh should coffee be when I finish the bag?
Specialty coffee tastes best within roughly 30 to 45 days of the roast date, after a few days of resting. Past about 45 to 60 days in an opened bag most coffees taste noticeably flat. If a bag will take longer than that, buy a smaller size or freeze part of it in an airtight container.
What bag size should I buy?
Pick the size you will finish in about three to four weeks. That is 8 to 12 oz for one cup a day, 12 oz to 1 lb for two cups, and 1 lb or more for a household. Our catalog lists 231 coffees in 12 oz bags and 55 in 10 oz bags, so the smaller sizes are widely available.
Does brew method change how long a bag lasts?
Yes. French press and cold brew use more coffee per cup than pour over or espresso, so a bag disappears faster. Change the dose above to match your method; our Brew Ratio Calculator gives the right dose for each one.
