Notes

Mashed with 5.5 gallons at 152 degrees for 60 minutes.
Sparged grains with 2 gallons of heated water to reach 7.5 gallons.
Pre-boil gravity was 10.51-1.052.
Increased boil time from 60 minutes to 90 minutes. Probably could have gotten away with around 75 minutes. My target fermenter volume should have been 5.5 gallons, but ended up being slightly less once the wort cooled.
Post-boil gravity was 1.066.
Cooled wort with immersion chiller down to 51 degrees in 24 minutes. Ambient temperature outside was roughly 41 degrees.
The color of the cooled wort is gorgeous.
The beer fermented for almost 7 days at a temperature ranging between 55-58 degrees. Days 2-6 were the most vigorous.
Sampled beer on day 7 and the gravity was 1.017!
Starting diacetyl rest on day 7 slowly taking beer up to 68 degrees.
