So I've made 2 BIAB partial mashes now.
The 1st was 5.5 lbs of grain, I mashed in 2 gal at 152F for 45 min, mashed out with 2 gal at 165F by "tea-bagging" in the sparge water and then letting it sit in the sparge water for 10 min. Efficiency was only 55%
2nd batch was 7.0 lbs of grain, mash in 2.25 gal @ 152F for 60 min, mashed out in 2.5 gal @ 165F "tea-bagging" plus soak for 10 min. I let the bag drain through a colander and squeezed the bag some for 30 additional minutes and did save more wort that way. only got 54% efficiency.
What is the deal? I've heard plenty of reports of 60-70% BIAB efficiency? Could it by my crush? I noticed that most of the grains are only crushed enough that they break in half..do I need a finer mill?
