To be classified as Bourbon, whiskey must contain at least what percentage of corn?

To be classified as Bourbon, whiskey must contain at least 51% corn in its mash bill. This specific requirement is significant because it distinguishes Bourbon from other types of whiskey. The corn content contributes to Bourbon's characteristic sweetness and smoothness, providing a unique flavor profile that sets it apart in the whiskey category. For a whiskey to legally bear the name Bourbon, it must also be produced in the United States and adhere to additional regulations regarding aging and distillation. The 51% threshold is a crucial aspect of Bourbon's identity, ensuring that corn is the primary grain in the production process.
