i've been ag for little over a year and i have a couple of questions. at first i was getting 80% efficiency using a bazooka tee, crushing my own grains using a corona mill, and mashing out. i've changed to a false bottom, and do not mash out, but now my efficiency has gone down to 70%. the crush is the same, i hold the temp, amount of strike water, is the same. the only difference is the false bottom and no mash out. could it be the false bottom or lack of mash out? for the sake of argument lets say everything is the same except for the false bottom and no mash out. could it be one of those or both? and yes i've just finished a brew day and have had a few. just getting frustrated at the efficiency getting lower.
