What percentage of corn must a whiskey have to be classified as bourbon?

To be classified as bourbon, a whiskey must contain at least 51% corn in its mash bill. This requirement ensures that the characteristic sweetness and flavor profile associated with bourbon come primarily from corn. The use of corn is a defining feature of bourbon as opposed to other types of whiskey, such as rye or malt whiskey, which have different grain compositions. This regulation is part of what sets bourbon apart and contributes to its unique taste and heritage, adhering to the standards established by U.S. law. The stipulation of a minimum of 51% corn distinguishes bourbon from other whiskey types, reinforcing its identity within the spirits industry.
