Bourbon's Used Barrels Now Flavor Global Spirits

The iconic oak barrel does more than just hold bourbon whiskey. It is a key ingredient, giving the spirit its color and vanilla-like flavors. But after its first use, a bourbon barrel's life is just beginning. By U.S. law, bourbon must be aged in new, charred oak barrels. This creates a huge supply of high-quality used barrels. Distillers worldwide now buy these "once-used" barrels. They use them to age other spirits, including Scotch whisky, tequila, and rum. The barrels impart a distinct, sweet bourbon character. This practice has created a global secondary market. It turns an American byproduct into a valuable tool for international flavor.
