Kegged 6/16/2016. Just enough to fit in the keg, nothing left to sample. Lost .25 gallons to 2 empties of collection ball.
Based on boiling 6.75 gallonsliters at 1.600 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.689. You wanted an OG of 1.072. It looks like it will be over.
