Bourbon is a type of American whiskey that is primarily made from corn, with at least 51% of its grain content being corn. It is typically aged in new charred oak barrels, which gives it a distinct flavor profile that includes notes of vanilla, caramel, and oak. To be labeled as bourbon, it must be produced in the United States and meet specific legal requirements. The origins of bourbon date back to the late 18th century, particularly in the Kentucky region. While many distilleries produce bourbon, some of the most famous brands include Jim Beam, Maker's Mark, and Buffalo Trace. Bourbon can be enjoyed neat, on the rocks, or as a key ingredient in cocktails like the Old Fashioned and Mint Julep.
