51 I think, from the attached, it is 30 %BV (no doubt someone will correct me if wrong)
S2: What is proof, and how do I figure the proof gallons of distilled spirits?
What is proof?
Proof is a method of measuring the alcohol content of spirits. You calculate the proof of a spirits product is by multiplying the percent of alcohol by volume by two (2). For example, a spirits product that has a 40% alcohol content by volume is 80 proof [40 multiplied by 2 = 80]. f?
Converting U.S. gallons into proof gallons for tax purposes:
1. Multiply U.S. gallons by the percent of alcohol by volume.
2. Multiply by 2.
3. Divide by 100.
Sample calculation:
1. 100 U.S. gallons x 40% alcohol by volume=4000
2. 4000 x 2=8000
3. 8000/100= 80 proof gallons
