Knob Creek Bourbon 9 Years – When it comes to making Knob Creek Bourbon, there’s a lot of waiting but hardly any sitting around. While each barrel patiently ages in white oak, our distillers continue to raise the standards, fulfilling their commitment to full flavor. The result? An unflinching balance of deep, pre-Prohibition-style bourbon with a robust oak taste, complemented with hints of smooth vanilla and layered caramel.
