Efficiency For:
An all inclusive measure of efficiency, which counts all losses to the fermentor. This can be thought of as 'to the fermentor' efficiency. Hops absorption factors into this, and is reduced on the same equipment by ~1% in super hoppy beers.
Wort Volume: (Gallons) How much wort went into the fermentor.
Gravity Measurement: (input adjust for temperature using this calculator. OG (measured after cooling, before pitching yeast).
