Black Button Single Barrel Straight Bourbon Whiskey is a small batch, single barrel bourbon whiskey made from a mash bill of 70% corn, 25% rye, and 5% malted barley. It is aged for four years in new, charred American oak barrels and bottled at 90 proof. The whiskey has a nose of caramel, vanilla, and oak, with a palate of sweet corn, toasted oak, and baking spices. The finish is long and smooth, with notes of toasted oak and baking spices.
