Barrell American Vatted Malt WhiskeyA new innovation from Barrell the American Vatted Malt is a blend of American Single Malts from various distillers across the country. Barrell sourced these limited whiskies and blended them to balance the contrasting flavor profiles. From Barrell Craft Spirits: This first release of American Vatted Malt was years in the making, as many of the components in the blend come from emerging distilleries that have never traded or sold bulk whiskey before.
