                                Bourbon is legally defined as a spirit produced in the United States from a fermented mash of at least 51% corn, and every bottle must contain a minimum of 40% alcohol by volume (ABV) or 80 proof. This alcohol is a byproduct of the fermentation process, where yeast consumes sugars from the grain mash.
