i recently heard of someone wanting to use spent grain from beer in order to distill some liquor. I know there's some sugar still left in spent grain, but it just doesn't make sense to me. at least, using only spent grain doesn't make sense. I did a quick search, but couldn't find anything really. it was all about baking bread or dog treats, or what the FDA says a commercial brewery has to do with it. I'll look into it more later, but i was wondering if anyone here knows if this is even possible or advisable?
