Wilderness Trail for sale, This Single Barrel release from Wilderness Trail is made from a mash bill of 64% corn, 24% wheat, and 12% malted barley, aged in toasted and charred barrels. It’s also bottled in bond, meaning that, as laid out in the Bottled-in-Bond Act of 1897, it must be aged between five and six years and bottled by us under the supervision of the U.S. Government at 100 proof. This is one of the highest ratios of wheat used in a Bourbon made in Kentucky. We entered the cooper select, toasted, and #4 char barrel at 110 proof after coming off the still around 137 proof. We then age our Bourbon in our two-story Rickhouse A, moving floors each year of maturation.
