I've never looked really closely at my spent grains (amazingly), but I did this last batch. I had little white blobs of what looked like oatmeal, just kind of mushy starchy stuff. It was starch-negative to iodine, along with the surrounding fluid, but if I smashed it up a bit, I got a heavy starch-positive test.
The batch was about 71% efficiency.
My thought is that I was losing starches this way. Perhaps it is inevitable, but do other people notice white blobs of starch left in the grains? I did a double decoction, and each boil liberated more starch, and that starch was broken down within a few minutes after returning to kettle, so the mash was then starch negative within minutes of each decoction return. Maybe I should go to a triple decoction!
Anyway, I also think the crush was a bit coarse. I purchase online, so the retailer has the mill, and I do not have one yet. I've asked them to check the mill and asked if I can request a double-crush. I have four more batches prepped from them, though, that all shipped together, so if it was a crush issue, I'm stuck with what I've got for now.
has anyone found any efficiency boosters or ways to get a consistent efficiency on their brew sculpture (three vessel single-teir herms with fly sparge and two pumps)? Any suggestions at all would be fun to discuss.
