Estimate mash or wash potential from a grain bill, batch volume, water volume, and mash efficiency.

This estimator assumes adequate starch conversion for converted mashes (for example, sufficient malted grain or enzymes where needed).

About This Calculator

  • Maltster: “All” shows every ingredient. Selecting a specific maltster shows its products along with generic ingredients when no branded equivalent exists.
  • Volume Used for OG: This is the liquid volume entering fermentation, not packaged beer volume after fermentation.

Batch Settings

Typical range: 0.10–0.15 gal/lb (default 0.12). Actual values vary with crush, drainage, and squeezing.

Recipe Notes

Notes:
Water Volume is optional, but if entered it is used to estimate mash thickness.
Mash Efficiency affects mash-derived fermentables such as grains.
In percentage mode, entered percentages are applied to total grain weight.
In Target OG mode, entered percentages are used to calculate ingredient weights needed to reach the target OG at the selected volume.
Direct fermentables are not reduced by mash efficiency.
In Sugarhead mode, grain-derived fermentables are excluded.
Actual results vary with process and equipment.
