What is bourbon primarily made from?

Bourbon is primarily made from corn, which is the defining grain that distinguishes it from other types of whiskey. According to U.S. law, for a whiskey to be classified as bourbon, it must consist of at least 51% corn in its grain mash. This high corn content contributes to bourbon's characteristic sweetness and rich, full-bodied flavor profile.

While other grains like rye, wheat, and barley can also be part of the mash bill in bourbon production, they are used in smaller proportions, typically to impart different flavor nuances. Rye adds spice, wheat contributes a softer mouthfeel, and barley aids in the fermentation process. However, it is the corn that plays the most crucial role in defining bourbon's identity and taste.
