What is the minimum percentage of corn required for bourbon production?

Bourbon must contain a minimum of 51% corn in its mash bill to qualify as a bourbon. This requirement is intrinsic to the definition of bourbon, as it distinguishes this type of whiskey from other types. The high corn content contributes to bourbon's distinctive sweet flavor profile and smoothness, setting it apart from whiskeys made primarily from other grains such as rye or barley.

In the production process, the mash bill, which is the mixture of grain used, is critical in defining the spirit's character and flavor. The remaining percentage of the mash bill can consist of other grains like rye, wheat, or malted barley, but the minimum 51% corn requirement must be met to ensure the spirit is classified as bourbon.

This regulation is part of the standards established by the U.S. government for the labeling and classification of spirits. Understanding this requirement helps guide consumers and producers alike in recognizing what constitutes genuine bourbon.
