What type of whiskey must contain at least 51% corn in its mash?

Bourbon is a type of whiskey that must contain at least 51% corn in its mash bill, which is the mixture of grains used in the fermentation process. This high corn content gives bourbon its distinctive sweet flavor, which is one of its hallmark characteristics. In addition to the grain requirement, bourbon must also be aged in new charred oak barrels, further contributing to its unique taste and characteristics.

The legal definition of bourbon was established by the U.S. government, but its roots can be traced to the early settlers of America who began distilling corn into whiskey. As a result, bourbon holds a significant cultural and historical place in American whiskey production. The use of corn is what differentiates bourbon from other types of whiskey, such as rye whiskey, which must contain at least 51% rye grain.
