BIAB water infusion: Allow 35 mins to get to starting temp (162F). Allow 15 min heat soak with insulation, brew bag (expect 2F drop to 160F strike temp). Brew Day : 3/18/2018 10:35am 8.9 gallons : started heating 10:11 temp @ 162F. Shutoff and lagged kettle. 1045am : temp @161F added grain. 10:48 lid on. Temp @ 154F (on target) 11:01am : temp @136F ???? Checked with instant probe 151.2F (phew) 11:52am temp @148.7F 12pm heat on. Refractometer : 1.045 (very low expected 1055 pre-boil). Hydrometer 1.047@64F = 1.047 (64% efficiency ... yuck). Added 1lb 3oz DME (all I had) but calculator stated 1.5lb needed per calculator Remeasured gravity refactrometer 1.055, hydrometer 1.056. 12:36 boiling. Day 8 3/25/2018 SG reading : 1.011 @ 66.9F = 1.012. 8.0% ABV. Transferred to secondary, added dry hops. Dropped temp to 65F. Thursday AM : dropped to 50F. 4/1/2018 SG reading 1.011 @ 66.9F = 1.012. 8.0% ABV.
Based on boiling 7.00 gallonsliters at 1.056 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.064. You wanted an OG of 1.072. It looks like it will be under.
