Final answer:
The minimum corn content required for an American Bourbon Whiskey is 51%, which is essential in giving it its distinct sweet and full-bodied flavor.
Step-by-step explanation:
For an American Bourbon Whiskey, the minimum corn content that must be present in the mash bill is 51%. This requirement is part of what distinguishes bourbon from other types of whiskey. Not only must bourbon have a majority corn mash, but it must also be aged in new, charred oak barrels, distilled to no more than 160 (U.S.) proof, and bottled at 80 proof or more. While higher corn content is not uncommon, the 51% baseline ensures that the final product has the sweet and full-bodied flavor characteristic of American Bourbon Whiskeys.
