I've recently been milling my grains on the tightest mill setting. I think my gap is about .028". I condition grains and get beautifully intact hulls, with a lot of fine grits.
On my last several batches I've noticed that I am getting a lot more wort from my standard water additions. For instance, this morning I used 9.1 gallons total water, and ran off 8.25 gallons of wort.
11 LBS of grain is only retaining .85 gallons of water. This is much less than I've experienced in the past.
Does anyone have similar experience? I think in the past, I'd figure on at least 1 - 1.5 gallon of lost wort per 10 LBS of grain.
