Snake wine (rượu rắn in Vietnamese) is an alcoholic beverage that inclues a whole venomous snake in the bottle. It originated in Vietnam and can be found around Southeast Asia. The snakes, preferably venomous ones, are usually not preserved for their meat. They are preserved to have the snake poison dissolved in the liquor. However, because snake venoms are protein-based, they are unfolded and therefore inactivated due to the influence of the denaturing effects of ethanol.
