Knob Creek Single Barrel Reserve is a premium bourbon whiskey aged for 9 years in charred American white oak barrels. It is bottled at a higher proof than the standard Knob Creek bourbon, and each bottle is hand-labeled with the barrel number and bottling date. The whiskey has a deep amber color and a rich, full-bodied flavor with notes of oak, caramel, and spice. It is best enjoyed neat or on the rocks.
