Based on boiling 11.50 gallonsliters at 1.042 for 90 minutes, this will decrease your wort by 1.50 gallonsliters, bringing your after boil OG to 1.047. You wanted an OG of 1.048. It looks like it will be under.
Pulled from Primary at 4 months and split into smaller batches. Very nice med intensity sourness at the time. Somewhat clean, looking forward to more brett production.
