Using 2 step batch sparge, is it more important to:
1. Aim for equal runnings
OR
2. Raise the temperature of the mash to 168F before the first runnings
My next brew:
16.5 lbs of grain
7.5 gallons pre-boil volume
To mash in, we use 22.6 qts (1.2 qts/lb-grain plus 2 qts dead space)
If aiming for equal runnings, after accounting for grain absorption, we only have to add 1.3 qts to get 3.75 gallons in the first runnings. This is nowhere near enough water, even at boiling temperature, to raise the temperature of the mash to 168F before the first running.
