25 years ago Jim Beam Master Distiller Booker Noe helped change the bourbon landscape with the release of Knob Creek bourbon. Knob helped usher in a small batch movement that continues to this day. To celebrate the anniversary of this important release, the folks at Beam are releasing a limited edition, unfiltered, cask strength, single barrel version of Knob Creek. It was aged for 12-13 years, and the proof ranges between 120-125. Since it's a single barrel release, there are slight nuances and variations with each barrel. The bottles arrive in a sharp, wooden box that features a unique label, including a handwritten bottling date and proof.
