A pound of coffee makes approximately 32 eight ounce cups of coffee depending on if you make it weak or strong. If you spend $10 for a pound of coffee and make it at home, you save about $30 over buying 32 tall coffees at Starbucks! Think about that during the current recession.
Directly from Starbucks website: 1 pound yields about 45 - 8oz cups.
The number of cups of coffee you can get from a pound of coffee varies, but you knew that. It depends primarily on the strength of the brew and the size of the cup, as you might have guessed. The range is 30 to 35 cups on the bottom, and 45 to 50 cups on the top for an approximately 8 ounce cup.
