Snake wine (r??u r?n in Vietnamese) is an alcoholic beverage that includes a whole venomous snake in the bottle. It originated in Vietnam and can be found around Southeast Asia. The snakes, preferably venomous ones, are not usually preserved for their meat but to have the snake poison dissolved in the liquor. However, the snake venom is denatured by the ethanol; its proteins are unfolded and therefore inactivated.
