Cruzan Black Strap Rum is a type of dark, molasses-based rum produced by the Cruzan Rum Company in the United States Virgin Islands. It is made using a blend of molasses, which is a byproduct of sugar cane processing, and natural caramel color, which gives the rum its distinct dark hue. The rum is aged in charred oak barrels, which impart flavors of vanilla, caramel, and spice to the final product.

Cruzan Black Strap Rum has a rich, full-bodied flavor profile with notes of molasses, brown sugar, and dark fruit. It is often used in cocktails such as the Dark 'n Stormy, which pairs the rum with ginger beer and lime juice. The rum can also be enjoyed neat or on the rocks.

Cruzan Black Strap Rum is one of several rums produced by the Cruzan Rum Company, which has been making rum on the island of St. Croix since 1760. The company takes pride in using locally-sourced ingredients and traditional methods to create high-quality, hand-crafted rums.
