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 classified as bourbon, it must be produced in the United States and adhere to specific regulations regarding its ingredients and aging process. The origins of bourbon can be traced back to the late 18th century, particularly in the Kentucky region. The name "bourbon" is believed to come from Bourbon County, where the whiskey was first produced. Today, bourbon is enjoyed worldwide and is a key component of many classic cocktails, such as the Old Fashioned and Mint Julep.
