Bulleit Bourbon Barrel Strength is a limited-edition bourbon whiskey from Bulleit Distilling Co. It is made from a blend of two- and six-year-old bourbons that have been aged in charred American oak barrels. The whiskey is bottled at barrel strength, meaning it is not diluted with water before bottling. This results in a whiskey that is higher in alcohol content and has a bolder flavor profile than the standard Bulleit Bourbon. The whiskey has notes of oak, caramel, and spice, with a long, smooth finish.
