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 #1 bourbon. This limited-edition offering is a tribute to that groundbreaking whiskey. Just like the original Old Tub liquid, this Kentucky Straight Bourbon Whiskey has not been carbon or chill filtered - only quality screened to remove bits of barrel wood to showcase the true, rustic character of the whiskey - bourbon the way it was intended to be.
