I have a brew session where the numbers don't make sense to me.
Here's what I think is the relevant info from the recipe (it's BIAB if that matters):
What am I missing or misunderstanding? Thanks in advance for any help understanding this.
Here's what I think is the relevant info from the recipe (it's BIAB if that matters):
- Efficiency: 70% (ending kettle)
- "Starting boil volume" under Water Requirements: 2.88 gal (it's for a 2.5 gal batch)
- "Recipe based estimate" of boil gravity: 1.048
- Pre-boil volume: 2.9 gal (i.e. essentially identical to what was expected)
- Pre-boil gravity: 1.051 (i.e. more concentrated than expected)
- Calculated pre-boil efficiency: 67% (i.e. less than recipe efficiency)
Theoretically the same as Pre-Boil Efficiency, provided accurate measurements at both points (minus rounding error)
