On my first Biab i used a default beersmith equipment profile and screwed up figuring it would be close enough. Today i figured i was all set but again had issues. Heres how it went. I set up a profile for my equipment as close as i can figure. I inputted the recipe into beersmith and it seemed to look right. My preboil gravity was spot on to the recipe but my post boil was alot higher 1.076 vs 1.069. and my post boil volume is low about 3 liters. I added 3 liters of water and it gave me 1.063. Its a bit lower than i hoped but ok. Todays brewday was alot more sucessful than my last all grain but im not sure where to look to fix my math now. any ideas? :smack:
