Bourbon is a type of American whiskey that must meet specific legal requirements in its production. Here’s what defines bourbon:

1. Ingredients: Bourbon must be made from a grain mash that is at least 51% corn. The rest of the mash typically consists of other grains like barley, rye, or wheat.

2. Distillation: It must be distilled to no more than 80% ABV (160 proof) and enter the barrel for aging at no more than 62.5% ABV (125 proof).

3. Aging: Bourbon must be aged in new, charred oak barrels. While there is no minimum aging period, to be labeled “straight bourbon,” it must be aged for at least two years.

4. Geography: Although bourbon is most famously associated with Kentucky, it can be made anywhere in the U.S.

5. Additives: No additives (other than water) are allowed in bourbon, meaning no flavoring or coloring can be added.

6. Alcohol Content: Bourbon must be bottled at no less than 40% ABV (80 proof).

Bourbon is known for its rich, smooth flavor profile, which often includes notes of caramel, vanilla, and oak, due to the aging process in charred barrels. It’s commonly enjoyed neat, on the rocks, or in cocktails like the Old Fashioned and Mint Julep.
