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. That's also known as 50% ABV across the pond.
