Rot gut whiskey is a type of whiskey that is made using sub-par ingredients and distilling methods, resulting in a product that is often lower in quality and has a harsher taste. It is a slang term for cheap and inferior liquor. The term "rot gut" is used to describe a low quality or dangerous alcoholic beverage, which is often made with poor quality ingredients or may be watered down, causing serious health problems, including liver damage and death. Rot gut whiskey is not necessarily unsafe to drink, but it is not as enjoyable as other types of whiskey. Some examples of rot gut whiskey include Old Crow, Evan Williams, and Old Overholt.
