ReadonlybrewhouseBrewhouse efficiency, %: extract that reaches the fermenter as a fraction of the grist's theoretical maximum. It's always ≤ mash efficiency. The gap is kettle deadspace, hop absorption and chiller loss.
ReadonlymashMash efficiency that was applied, %.
ReadonlymaxTheoretical maximum extract of the whole grist, point·litres.
ReadonlyogOriginal gravity, what a hydrometer reads on the wort going into the fermenter.
ReadonlyogOG-equivalent: the gravity the wort would have had if every later sugar addition (fermenter honey, dextrose at high krausen) had gone in the kettle. ABV has to be computed from this figure.
ReadonlypostGravity at the end of the boil, corrected to 20 °C. Equal to og.
