Brewhouse Yield at 66% target brewhouse yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target brewhouse yield to 66%, then walk the calculation through step by step. Calculate brewhouse yield from collected wort or distiller's wash volume against the planned batch volume, with a target yield for production review.

The inputs for this scenario

  • Usable wort or wash collected: 28.5 bbl (held at the documented default)
  • Planned cast-out volume: 31 bbl (held at the documented default)
  • Target brewhouse yield: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Brewhouse yield = usable wort or wash collected ÷ planned cast-out volume × 100.
  • Brewhouse yield works out to 91.94 % brewhouse yield at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to -25.94 points at these inputs.
  • Usable wort or wash collected works out to 28.5 bbl at these inputs.
  • Planned cast-out volume works out to 31 bbl at these inputs.

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.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target brewhouse yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Volume yield alone ignores gravity — you can hit volume while missing extract — so pair it with a gravity or extract-efficiency check for the full picture.

Results at a glance

  • Brewhouse yield: 91.94 % brewhouse yield (headline result)
  • Yield gap to target: -25.94 points
  • Usable wort or wash collected: 28.5 bbl
  • Planned cast-out volume: 31 bbl
