Based on boiling 6.50 gallonsliters at 1.058 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.067. You wanted an OG of 1.056. It looks like it will be over.
Opened a few bottles today...Happy New Year, the malty, caramel, hop is just so well rounded...not going to touch this recipe....brew again for sure.
