As the name suggests, this version is composed of four different barrel-aged components: the base imperial stout that was aged in both whiskey and rum barrels with cacao nibs for between four and 12 months; Colombian coffee beans from Blue Copper that were aged in fresh whiskey barrels; barrel-aged almonds, and shaved coconut that was aged in fresh whiskey barrels. All of the components were then blended together into the final product before being packaged in 22-ounce bottles, with approximately 500 bbls available.
