Grain Bills

Unread postby Husker » Sun Nov 09, 2008 2:51 pm

Does anybody know about how much grain is used to make bourbon? For example, how many
lbs. of grain goes into a gallon of 120 proof.

Also, does anybody ferment on the grains or do they all pour off the beef before fermenting?

Thanks

Spirit for bourbon typically comes off the still at 140 proof. Typical yield is a bit more than five gallons of 140 proof spirit per bushel of grain.

Thanks, Cowdery. At 52 lbs./bu that's 10 lbs/gal. That's a lot of grain. Do you think it would be fair to figure about 8 gal of low wines to get that 5 gal of spirit?

Every distillery runs a little different, but the doubler doesn't remove that much additional water. The second distillation is mostly about fine-tuning the congener composition, and congeners don't account for much volume. It raises the ABV maybe five to seven percent.
