I've been looking over Kaiser posts but can't figure out the answer to this.
It there a way to figure out the gravity of each running in a batch sparge?
The decline in gravity must follow some sort of curve.
Say my first runnings and two batch sparges are all equal volume and I knew that my total pre-boil wort gravity was 1.042. Using a half-life assumption I'd get:
First Runnings = 1.072
First Batch Sparge = 1.036
Second Batch Sparge = 1.018
That's guessing that each running has half the gravity as the one before, but that is just a guess. Anyone know what that number actually is?
