What percentage of corn is required for Tennessee whiskey production?

Tennessee whiskey production requires a minimum of 51% corn in its grain mash bill. This requirement aligns with the definitions established for bourbon and whiskey production in the United States, where a mash bill must contain more than half corn to be classified as such. The significant corn content is necessary not only for legal classification but also for the whiskey's flavor profile, contributing sweetness and a smooth mouthfeel, which are characteristic traits of Tennessee whiskey.

While other options suggest varying percentages, the 51% threshold is the specific minimum mandated for it to qualify as Tennessee whiskey. Using below this threshold would not meet the legal requirements set forth by regulations governing American whiskey production, thereby defining the whiskey's essential characteristics.
