Also I get about the same mash efficiency with my MM2 at 1.042 or 1.035.
ok just to make sure we are talking the same thing, because I just spoke with a guy at the LHBS who claims 95% efficiency.. I told him you mean Mash eff and he says No total efficiency.. Mash Efficiency is how much sugar the MASH itself produces relative to hypothetical maximum yields . To Check Mash efficiency get the Gravity of mash befor sparge (With 37 pts per pound of 2 row being the average lintner)
It's the gravity points obtained divided by the 100% possible gravity points
So 10# 2-row in 4 gal mash water = 37pts x lbs / gal. 370/4=92.5 max yield efficiency in points (convert to gravity 1.092)
So at 100% efficiency I'd get a gravity reading after mash of 1.0925
If I got 1.083 reading (at the end of MASH before Sparge). I would divide that by 1.092 and get 90% mash efficiency ( 83/92= .90 X100 = 90% ) Thats a decent Mash efficiency. Total efficiency is the gravity points you still have when the wort reaches the fermenter.. Many people mix that up.. thats why its good to clarify which efficiency your talking about. In my system I consistently get 80% Mash effc, but cant seem to get better then 70% into the fermentor.. So in this scenario above i would expect a OG in the fermenter of 1.062 Is it my crush?
