Based on boiling 36.50 gallonsliters at 1.052 for 90 minutes, this will decrease your wort by 9.00 gallonsliters, bringing your after boil OG to 1.065. You wanted an OG of 1.069. It looks like it will be under.
Full bodied, distinct grain flavor, very happy for a Lager of this type. the only downside is a little down on the head retention
