Yesterday I did my 12th brew. My third in my current equipment setup. All-Grain BIAB where my efficiency has been consistently over %70. My previous brew, an IPA I hit all my numbers. I changed no variables for this beer except of course the recipe. I striked at 158F, mashed for 90 minutes at 153F (stirred many times). My one gallon recipe:
- 1.5lb White Wheat Malt
60 min boil on .2oz Tettnang.
Post mash, I lost .125 gallons of water as expected (left with 2 gallons in pot). Hit a pre-boil gravity of 1.022. Was expecting 1.027. I guess that doesn't seem huge, but come end of boil I had .1 gallons of trub and 1 gallon of wort, which measured in at 1.035. Any ideas as to what would have led to numbers like this? And what steps should I take in the future to ensure better numbers? I ask about the white wheat in particular because it is the only ingredient I have not used in a mash before (link to malt)
