OK, read post earlier that trailed into batch sparging and efficiencies. After the vorlouf and first running - you add volumes for the batch sparge additions. Do you stir the grains after the additions and then re establish the filter bed with the next vorlouf or not stir and let the original running bed be stable?? Seems to me like the batch additions are messing it up anyway and stirring prior will give better efficiency etc?? I am just farting right?? thanks, doc
