The Estate Diamond Rum draws its name from that original sugar mill. This dark rum is a masterful blend of 5-12 Year Old rums aged in American oak barrels. With rich notes of oak and vanilla, it's perfect for sipping straight or on the rocks. In 1760, a sugar mill began crushing cane at the current site of Cruzan Rum's distillery on the island of St. Croix. Since the early 1800s, the Nelthropp family has lived on and been an integral part of this legendary island's rich history.
