Just came across a quite interesting video of a Sotol producer infusing his spirit with rattle snakes, live ones too. It takes around 12 hours for the snake to drown in the alcohol, after that it is gutted and put back into the bottle for further infusion. It is said that the snake has a lot of medicinal purposes and is a natural aphrodisiac. i have seen this before in Vietnam, where producers of high abv rice spirit (rice wine) treat their product in the same way. I have not tried the snake infused Sotol, but i have had a few incidents with the Vietnamese version, and i can tell you as much as i rather not have that particular medicine again.
