I just ran this calculation again because I couldn't believe it. The BF efficiency calculator told me I got 32.6 PPG and 92% extraction efficiency. I entered all the malts, which consisted of 10 lbs Viking Pale, 2 lbs Canada Malting Malted Oats, and a smattering of other things, 14.5 lbs total. I entered the total water used as 5.5 gal. for the mash (BIAB) and 2 for the dunk-sparge, total of 7.5 gal. Pre-boil gravity, prior to top-up, was 1.063, temperature-corrected. Is such a thing even possible? Where could I have made a mistake?
