Based on boiling 12.20 gallonsliters at 1.053 for 90 minutes, this will decrease your wort by 1.50 gallonsliters, bringing your after boil OG to 1.060. You were planning on an OG of 1.060 so you are right on track. Nice job!
Really solid beer for the first all grain batch. 6.7%. Used whirlfloc for clarity instead of irish moss.
