Long time user here, but ran into a problem I can't seem to find an answer to. I built a recipe with a pre-boil gravity and volume of 1.062 and 7.5 gallons, respectively. Boil off is 0.75 gallons. I add one pound of sugar at the end of the boil. Based on that math I should have an OG off... Pre-boil gravity: 1.062 Pre-boil volume: 7.5 gallons Boil Off: 0.75 gallons Post-boil volume: 6.75 gallons 62 gravity points / (6.75 gallons / 7.5 gallons) = 69 gravity points Calculated post-boil gravity: 1.069 Add 1 lb sugar late in the boil, which should be ~46 ppg. 46 points / 6.75 gallons = ~7 points total Estimated gravity to the fermenter: 1.069 + 1.007 = 1.076 OG The recipe builder is telling me my OG should be 1.085. Anybody got any good ideas as to what's going on? I'm confident in my math, but why is BF giving me such a drastically different answer?
