I brewed a batch of beer today, which was 9#4oz British 2row and 12oz 120L crystal malt. I ended up w/ an OG of 1.060. When I did some quick calculations, it looks to me like there is a possible total of 35.5 gallon points theoretical max, where as I ended up with 33 gallon points. This would be an efficiency of over 90%, which I tend to believe is NOT what I'm getting. I set the crush on my barley crusher 1/4 turn tighter, which made for a much finer crush, but the sparge took too long for what I want to spend on a batch. In any case, is my math correct here?
