Barrell Bourbon Private Release A40i is a limited edition bourbon whiskey produced by Barrell Craft Spirits. It is a blend of two straight bourbons, one aged for 12 years and the other for 15 years. The whiskey is bottled at cask strength, meaning it is not diluted with water before bottling. It has a deep amber color and a complex flavor profile of oak, caramel, and spice. The finish is long and smooth, with notes of vanilla and toasted nuts. This whiskey is best enjoyed neat or on the rocks.
