I have been using beersmith 2.0 for about 2 years now and I just don't get brewhouse efficiency and how to use it to accurately hit my OG. For today's brew session (Lemon Weiss) here are the numbers:
Pre-boil volume = 8.11 gal
Pre-boil gravity = 1.041
Mash efficiency = 75% (estimated was 74%)
So I am mashing as predicted based on my system.
Then when I go to boil I hit my post boil volume numbers but my OG is always less than that beersmith predicts.
My OG for this batch was 1.05 with a post-boil volume of 6.5gal.
After cooling I transferred 5.5gal in the fermenter (0.5 shrinkage, 0.5 trub).
So I put in beersmith that the batch size is 5.5gal and my OG is 1.05 and my brewhouse efficiency is 63% not the predicted 70% efficiency it says it should be. Based on the 70% efficiency my OG should be 1.055
What am I doing wrong? Or is it just a matter of how beersmith uses "batch size". If I put these same measurements in brewers friend, it says with a gravity of 1.04 at 8.11 I should hit 1.05 at 6.5 which I did. But because 5.5gal goes into the fermenter, somehow that changes my OG?
