Our high in small grain Kentucky Straight Bourbon Whiskeys are offered as a Small Batch - Bottled in Bond. The Small Batch selection offers nuances only premium cooper select barrels can create using 18-month-old air-dried staves. After all, the barrels impart a large part of the flavor. What is a Small Batch? At Wilderness Trail, it's 18 barrels per batch, which was the result of one fermenter. In addition, the Bottled in Bond gives you assurance the Bourbon was properly distilled, aged between 5-6 years and bottled by us under the supervision of the U.S. Government at 100 proof. Our Bottled in Bond release mash bill is 64 percent corn, 24 percent wheat and 12 percent malted barley using our yeast strains. This is one of the highest ratios of wheat used in a Bourbon made in Kentucky. We entered the cooper select, #4 char barrel at 110 proof after coming off the still around 137 proof. All of our whiskeys are aged and matured on our 168-acre campus inside any one of our rickhouses. We have more than 250,000 barrels aging onsite.
