Wondering where to go from here.... I have read a ton on mash efficiency.....I have consistently gotten low efficiency from batch sparging and can't really nail down the cause other than the crush. I set my Barley Crusher at .034 and have tried going smaller than that only to find that the grains will not go thru the mill at .026-.030. My PH is in check according to JP's spreadsheet, and sparge temp has been raising the grain bed to approx 160-170 for sparging. I stir twice during the mash and again after the batch sparge water is put in wait ten minutes, vorlauf and drain.
Have heard from several respected sources that runoff rate for 1st runnings and sparging either make for better efficiency BUT then others say to runoff as fast as possible as runoff rate does not matter in batch sparging.
I need a way to crush smaller (with my mill) and a way to know "for sure" what my runoff speed should be.
Any proven ideas would be much appreciated. Thanks !
