Before Jim Beam Bourbon, the Beam family made Old Tub, an unfiltered bonded bourbon which was the foundation for what would become the world's number one bourbon. This limited-edition bourbon is a tribute to the groundbreaking whiskey. Just like the original Old Tub, this Kentucky Straight Bourbon Whiskey has not been carbon or chill filtered. The recipe showcases the true, rustic character of the whiskey, the result is bourbon the way it was intended to be.
