So, I completed my 2nd AG brew a few weeks ago, and it was the first that I had taken enough measurements to calculate mash and brewhouse efficiencies. I was a bit surprised by the result. Beersmith tells me that my mash efficiency was about 83%, but my overall brewhouse efficiency dropped to 68%. I'm happy with the mash efficiency, but I am surprised that I lost so much efficiency during the boil, and everything I've read so far only gives tips on increasing mash efficiency. Any idea on what I could have done wrong to lose so much efficiency during the boil? What I can change to keep the efficiencies in line?
Preboil gravity was 1.034, rising to 1.038 after a 90 minute boil. I had 7.5 gallons going into the boil, put 5.5 gallons into the fermenter and had about 0.5 gallon lost to trub \ left after hitting 5.5 gallon.
Thanks!!
