ReadonlyboilWater evaporated during the boil.
ReadonlychillerWort left in the chiller and hoses.
ReadonlydecoctionWater the decoction pots boil away, litres.
A mash loss like any other (it leaves the tun and never reaches the
kettle), but infusion mashes don't have it, so it's zero for almost every
recipe. ./decoction explains why it can be known before the pulls are
sized. That's what lets it be a plain term in the waterfall, with no need
to iterate.
ReadonlydryBeer retained by dry hops.
ReadonlyfermenterBeer left on the yeast cake and trub.
ReadonlygrainWater retained by the spent grain.
ReadonlykettleWort left under the kettle pickup.
ReadonlykettleWort retained by boil and whirlpool hops.
ReadonlymashVolume below the mash tun outlet, which returns to the kettle.
Reported for display only, and excluded from every other number here. It costs no water and isn't part of totalLossL.
ReadonlymashWort actually left behind in the mash tun.
ReadonlymashStrike water plus the volume the grain itself occupies. Check this fits the tun.
ReadonlypackagedFinished beer into keg or bottles.
ReadonlypostWort at the end of the boil, still hot.
ReadonlypostWort at the end of the boil, corrected to 20 °C. The measurement basis.
ReadonlypreWort in the kettle when the boil starts, at boiling temperature.
ReadonlyshrinkageVolume lost to thermal contraction as the wort cools to 20 °C.
ReadonlyspargeWater used to rinse the grain bed. Zero for no-sparge and BIAB.
ReadonlystrikeWater into the mash tun.
ReadonlytopWater added to the fermenter after transfer.
ReadonlytopWater added straight to the kettle (extract and partial-boil brewing).
ReadonlytotalTotal boil-off + shrinkage + every loss.
ReadonlytotalStrike + sparge.
ReadonlyvolumeChilled wort into the fermenter.
Every stage of the volume waterfall, litres.
