The Bonampak Dark Rum Double Cask Aging is an 80 proof rum that has been aged in two different types of oak barrels. The first barrel is a charred American oak barrel, which imparts a smoky flavor to the rum. The second barrel is a French oak barrel, which adds a hint of sweetness and complexity to the rum. The result is a smooth and flavorful rum with notes of caramel, vanilla, and oak. This rum is perfect for sipping neat or in a variety of cocktails.
