Beverage Brewing, Distilling & Fermentation calculator
Brewhouse Yield Calculator
Brewhouse yield shows how much usable wort, wash, or fermented beverage base makes it out of mashing, lautering, boiling, whirlpool, and transfer compared with the planned batch size. Brewers, distillers, and beverage production managers use it to spot extract, trub, evaporation, and transfer losses before they affect fermentation volume or finished goods cost.
What this calculator does
- Calculate brewhouse yield from collected wort or distiller's wash volume against the planned batch volume, with a target yield for production review.
- a brewery, distillery, cider house, or fermented beverage plant needs to compare actual kettle or fermenter fill volume with the expected batch volume
- Returns actual brewhouse yield as a percentage of the planned cast-out or transfer volume.
Formula used
- Brewhouse yield = usable wort or wash collected ÷ planned cast-out volume × 100
- Yield gap to target = brewhouse yield - target brewhouse yield
Inputs explained
- Usable wort or wash collected: Use the volume available for fermentation after mash, lauter, boil, whirlpool, trub loss, and transfer loss.
- Planned cast-out volume: Use the target wort, wash, cider, or beverage base volume for this recipe before fermentation.
- Target brewhouse yield: Use the standard yield target for the recipe, brewhouse, grain bill, or mash process.
How to use the result
- Use it after knockout, wort transfer, wash transfer, or batch closeout to review extract capture and liquid losses.
- It is a volume yield estimate; it does not correct for gravity, Plato, extract mass, temperature expansion, or alcohol conversion unless your volumes are normalized consistently.
Common questions
- Should I use hot or cold volume? Use the same basis for both fields. Cold-side fermenter volume is best for production planning because it matches tank fill and downstream yield.
- Does this calculate extract efficiency? No. It compares collected volume to planned volume; extract efficiency also needs gravity or Plato readings.
- Can distilleries use this for wash production? Yes. Use usable wash volume collected for fermentation and the planned wash batch volume.
- How can I use the result? Use it to adjust recipes, investigate lauter or trub losses, schedule fermenter fills, and update cost per barrel or gallon.
