Look for Wilderness Trail’s wheat and rye Bourbon with a silver label and a “6” on the neck tag and on the vertical label. The silver label mash bill for the wheated Bourbon is 64% corn, 24% wheat, and 12% barley. For the rye Bourbon, the difference is 24% rye instead of wheat. The 6-year is deeper in character and richer in flavors found in more mature Bourbons. We hope you enjoy all the deliciousness of our Bourbons with this age statement. urban.
