I did my first AG brew this weekend, a SMASH Citra brew. The target OG was 1.055, after batch sparging I tested the 6.5 gallons of wort and came up with 1.044, but completely forgot to test again after boiling down to about 5 gallons (I'd had quite a few home brews while boiling). How much does the OG usually raise to after boil off. I would assume it raises some due to water boiling off. True? If so how much of a raise do people usually see?
Forgot to check OG after boil

The formula is pre boil volume * by gravity points divided by post boil volume. Using your volume estimates and pre boil gravity it would look like this (6.5 * 44) = 286 / 5 = 57.2 or 1.0572. The results will only be as close as your volume estimates are but it'll give you a ballpark number.

Or, don't worry about it. What can you do at this point to change it?
