Interesting read. I think I might investigate the PH on the side, but focus on the crush.
I also think that next time I batch sparge, I'll combine into one batch or decrease the initial ratio.
I add the grain to the water then stir pretty good with a paddle. I think i might have to ask them to run it though twice. I saw a few grains that look like they hadn't been crushed at all.
I am using a refractometer, so getting the temp down wasn't an issue. I buy the grains milled from a local homebrew store and store them at room temp (78). from milled to brewday it was 2 days.
Yea, i checked all that. I had this issue two batches ago (50%), but the last one was near 75%. I thought I had all the kinks sorted out.
I'm using tap water, can water chemistry play that big a difference? I have no idea what my PH level is...
I am hoping to get help on my efficiency problems. This last batch I got about 40%, and missed my target by a good bit.
I am using a 10 gallon beverage cooler with a bazooka tube.
This last 5 gallon batch had 16lbs 6 oz of grain as follows:
11 lbs Pale Malt (2 Row) US
5 lbs Munich Malt
