All of Bourbon Barrel Foods items are handcrafted in small batches in Louisville, Kentucky. They use reclaimed barrels straight from Kentucky’s finest bourbon distilleries as both a smoking and aging agent. The process imparts an added dimension of flavor that cannot be replicated using any other method. Their signature product, Bluegrass Soy Sauce, is the only microbrewed soy sauce made in the United States and the ONLY soy sauce in the world fermented and aged in bourbon barrels.
