this is more of a rhetorical question,i know the answer now,but till yesterday i didnt,while playing with the newest version of beersmith i looked at my brew house efficiency=58% did some digging around and turned out that more normal range is 70-80!! i never paid attention to it before,always get my grains crushed at the store,that is run by my good buddy,now however i thing is time to shell out on new equipment.cheers!
