Screwed up somehow with the measurements and ended up with more wort than expected. OG is pretty low...cross my fingers on this one
Based on boiling 4.50 gallonsliters at 1.037 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.045. You wanted an OG of 1.048. It looks like it will be under.
