The brewer who bought the coffee recently dropped off a couple bottles for me to enjoy so I asked how much beer he gets out of 6 pounds of coffee. The answer was 3 barrels.
I don't know where they're selling it, but the product name is "Cuppa Joe" and it's from Racine Brewing Company if anybody wants to try it. I'll be opening a bottle tonight after work.
