I had a distressingly low efficiency this weekend (~50%) for reasons that are unclear. I usually hit 70-75%. I crushed the grains at my LHBS with a MaltMill they have available for customer use. I set it to the finest setting, which is what I've done in the past. However, I've never done an AG wheat beer before, which this was (a weisenbock.) Is it possible that my crush was too fine, and this hurt my efficiency?I would think that the finer the crush, the better the efficiency, and that the only limiting factor on crush would be potential stuck sparges. Is that wrong?
There seemed to be a fair amount of flour after the crush, and while the wort cleared of larger hull pieces within a cuople of quarts of vorlauff, it stayed cloudier than I was expecting. Maybe that's due to the wheat; I don't really know.
Grain bill was 8 lbs wheat malt (Germany), 4 lbs Pils (Germany) and .5 lb Crystal 60L; mash tun is a 60 qt IceCube cooler with stainless steel braid loop. Mash was a single step at 155 for 1 hour. Sparge was a double batch sparge.
