Bourbon is America's native spirit, a whiskey defined by law and tradition, crafted from corn and aged in new charred oak barrels to create its distinctive sweet and oaky character. Federal regulations strictly define what can be labeled as bourbon, protecting both consumers and the category's integrity.

To be called bourbon, a whiskey must be produced in the United States, made from a grain mixture that's at least 51% corn, distilled to no more than 160 proof, entered into the barrel at no more than 125 proof, and aged in new charred oak containers. It must be bottled at 80 proof or higher.

Kentucky produces the vast majority of bourbon, thanks to its limestone-filtered water, climate, and long distilling tradition. However, bourbon can legally be made anywhere in the United States, and craft distillers across the country are creating distinctive regional expressions.

The aging process is crucial to bourbon's character. The new charred oak barrels impart vanilla, caramel, and wood spice notes while the liquid's interaction with the wood creates the amber color. Kentucky's temperature variations drive the whiskey in and out of the barrel's wood, accelerating flavor development.

From the classic Old Fashioned to the Mint Julep, bourbon has inspired countless cocktails while also standing proudly on its own as a sipping whiskey. The category has experienced a renaissance, with both heritage brands and innovative craft distillers pushing boundaries while respecting tradition.
