Hah. I was sitting here messing with beersmith, watching TV, and I saw a commercial for this. I decided to just see what the gravities would be for 64 calories and 3% (which is probably rounded up from 2.8 or so)
Naturally my curiosity kicked in and I figured I'd make a recipe.
2.25 lb pale 6-row
.5 lb flaked corn
.5 lb flaked rice
.25 oz williamette for 60 min -> 6 IBU
4 tablets beano crushed in primary after 4 days
That's 3.25 lb of grain for a 5 gallon batch. You could probably do that in a little cooler normally used for PM.
