I hit my preboil gravity of 1.068. Post boil gravity as supposed to be 1.077 but instead was 1.058. I think I know what went wrong.
1. My starter contributed 1.5 quarts that I don't think B.S. accounted for.
2. My evaporation rate was less than I programmed. It was only .7 gallons instead of the 1 gallon that I programmed.
Still the above additional water doesn't seem like it would cost me 19 gravity points. I'm trying to figure out what to change in B.S. to account for this so that next time it accounts for all this and I can hit my post boil gravity. I couldn't keep the boil going because it was an IPA and I didn't want to over boil the late hops additions.
