Beverage Brewing, Distilling & Fermentation worked example

Brewhouse Yield at 99% target brewhouse yield: a worked example

This scenario runs the brewhouse yield calculation on the strong side: 99% target brewhouse yield, with every other input held at its documented default. a brewery, distillery, cider house, or fermented beverage plant needs to compare actual kettle or fermenter fill volume with the expected batch volume

The inputs for this scenario

  • Usable wort or wash collected: 28.5 bbl (unchanged)
  • Planned cast-out volume: 31 bbl (unchanged)
  • Target brewhouse yield: 99 % (raised for this scenario; the documented default is 92)

Working through the calculation

  • Applying the documented formula (Brewhouse yield = usable wort or wash collected ÷ planned cast-out volume × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 91.94 % brewhouse yield for brewhouse yield, the number this scenario is built around.
  • At this operating point the engine returns 7.06 points for yield gap to target.
  • At this operating point the engine returns 28.5 bbl for usable wort or wash collected.
  • At this operating point the engine returns 31 bbl for planned cast-out volume.

How this compares with the baseline

  • Against the tool's baseline example, where target brewhouse yield sits at 92% and the headline result is 91.94 % brewhouse yield, this scenario lands almost exactly on the baseline at 91.94 % brewhouse yield.
  • Use it at knockout on every batch to verify collected volume against plan and to trend lauter and evaporation performance over time. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Brewhouse yield: 91.94 % brewhouse yield (headline result)
  • Yield gap to target: 7.06 points
  • Usable wort or wash collected: 28.5 bbl
  • Planned cast-out volume: 31 bbl
