General Info

Used 2 gallons of first-ish runnings to boil down separately and get some kettle carmelization.

Collected about 17 gallons in the primary boil kettle -- sparge was still around 1.020 when I finally stopped.

Boiled the 2 gallon down to 1 gallon and eventually added it to the main BK.

Had to boil the whole thing for about 4 hours to eventually get down to the proper volume.
