While the mashbills aren’t disclosed, standard 1792 releases are high-rye, meaning the secondary grain is rye. In this case, Barton used a larger wheat percentage for a “softer” bourbon.
Barton’s tasting notes: Notes of vanilla and caramel are complemented by a touch of white oak tannins. This is further mingled with dried fruit to deliver a richly smooth flavor.
Originally released in Summer 2015, Sweet Wheat’s inaugural release was distilled in 2007, making it about 8 years old.
