What is the difference between Proof Gallon and Wine Gallon?
Since the Federal Govt. taxes by the “Proof Gallon”, the proof becomes significant in taxable situations. For instance, 200 proof, pure Ethanol has two (2) “Proof Gallons” per every one (1) gallon of Alcohol. The actual physical quantity of one (1) gallon is then referred to as a “wine gallon.” 190 proof Ethanol has 1.9 proof gallons per wine gallon of Ethanol. One gallon of Vodka (80 proof) has 0.80 proof gallons of Ethanol. So, we have proof gallon and wine gallon as additional descriptions for the content of Ethanol product.
