Looked up on the www. about the proof of Moonshine and found this...
Moonshine is often above 100 proof, 200 proof being 100% alcohol.
Also said most Moonshine is around 190 proof.
The Popcorn Sutton Whiskey they sell now is 93 proof.
Here's something else I read...
Everyone instinctively knows that “XXX” written on a jug indicates that it contains moonshine, but what does that symbol mean and why did moonshiners scrawl that on their jugs?
The “XXX” signifies how many times the moonshine batch had been run through the still. Three X’s indicated that it had been run through three times and that the shine was pure alcohol.
