I have been brewing AG for about a year and a half and I have been using the same equipment the whole time (cooler MLT, 40qt pot). For the first year I was getting efficiencies in the high 70's and low 80's. For about the last 8 batches, I am struggling to hit 70%, and I have NO clue why! I can rule out my LHBS's grain mill, i have a friend who buys from the same store and he is hitting high 80's. The only changes to my equipment are I replaced my immersion chiller with a CounterFlow and my braided hose has gotten a little beat up, so I have to be extra sure i vorlauf.
Can anyone come up with any reasonable theories as to what is happening? All of my process has been consistent, and I've been real meticulous in making sure i'm hitting mash temps and holding them throughout the mash.
