Distillation Charge, Cut, and Proof Gallon Yield
Computes absolute alcohol, wine gallons, proof gallons, and excise from a wash charge, recovery, and the hearts cut.
Example
You enter
- Wash charge (gal) 500
- Wash alcohol by volume (%) 8
- Still alcohol recovery (%) 85
- Collection proof 140
- Proof after cutting 80
- Hearts share of recovered alcohol (%) 75
- Excise rate ($ per proof gallon) 2.7
You get
- Absolute alcohol (gal) 40
- Absolute alcohol recovered 34.00 gal of 40.00 in the charge
- Wine gallons 48.5714
- Proof gallons 68
- Alternative wine gallons 85
- Alternative proof gallons 68
- Excise on the run $183.60
- Hearts, the saleable spirit 51
- Hearts excise 137.7

Details, formula, and sources
ScopeThe worked 500 gal of 8% wash gives 68.0 proof gallons whether gauged at 140 proof or cut to 80 -- always twice the absolute alcohol. The hearts are 51.0 PG and $137.70 of excise at the rate entered.
Formula or tableabsolute alcohol = gal x ABV x recovery; proof gallons = wine gallons x proof / 100 = 2 x absolute alcohol; excise = PG x rate.
