I’m pretty new to homebrewing and am now 2 batches in to BIAB. I use a 5 gal kettle and am doing full volume, no sparge batches of usually 2.75 gal into the fermenter (roughly 2.5 gal bottled). I was wondering if anyone else is doing something similar and what their grain absorption and boil off numbers look like. My grain absorption is about 0.045 gal/lb and boil off is about 0.5 gal/hr. My numbers seem really low compared to most of what I’ve seen out there. I boil on my stove and my kettle has a diameter of about 11.5 inches. I’ve had to change a lot of parameters in BeerSmith to get my recipes dialed. Current efficiency is about 75%. Am also considering adding a fly sparge to try to bump that up though.
