How to Use This Calculator

Enter the wash volume and wash ABV percentage.
Select the still type (pot still, reflux, column) and collection efficiency.
The calculator shows distillate volume, output ABV and proof, pure alcohol collected, and alcohol remaining in the wash.
Use output ABV to determine how much dilution water to add before bottling.

How the result changes with Wash Volume

Wash Volume: Volume of fermented wash to be distilled in liters.
Wash ABV: Alcohol by volume of the wash. Grain washes are typically 6-12%, sugar washes 8-14%.
Still Type: Type of still: 1 = Pot Still (~63% ABV output), 2 = Reflux Still (~87% ABV), 3 = Column Still (~93% ABV).
Collection Efficiency: Percentage of alcohol actually collected. Some is lost in foreshots, tails, and residual wash. 80-90% is typical.
