I brewed a batch of beer today where the grain bill was 16.75 lbs. My effieciency on my last three brews has been 80%-90%...well on this brew I got a whopping 65%. I believe there are two reasons:
1) The grain crush from the closest LBHS is really bad. I've been driving about 35 minutes to a different one but didn't have the energy just recently.
2) I needed 4 gallons to sparge with. Well I've been double batch sparging the past month or so with fantastic results, so that's what I did here. I split the sparge into two 2 gallon batches. It dawned on my later that 2 gallons probably isn't enough to rinse sugars from 16.75 lbs of grain, so this might've been a factor in my terrible efficiency as well.
What does everyone think?
