I just noticed something that that is confusing me.
I just brewed a small batch brew, first time using this equipment profile, (BIAB, no losses, everything from kettle goes in fermenter, if that matters).
The preboil gravity estimate was 2.16 gal at 1.043.
I hit the gravity right on, didn't bother measuring my actual volume.
Post boil estimate is 1.56 (hot)gal, at 1.062.
I only measured 1.057 or 58, and thought well, dang... oh well, and carried on, thinking I likely didn't boil off enough (first time using this small batch pot and boil off estimate may been off).
But then I realized... I don't think the math works out... unless I don't understand the math?
Pre-boil: 2.16 x 43 = 92.88
Post-boil: 92.88 / 1.56 = 59.53
So shouldn't the post-boil gravity estimate be 1.56 gal at 1.060?
It's only a 2 point difference, but I like to understand the math behind what's going on.
