Carefully blended and aged by the same recipe and standards of its 80 proof sibling, Goslings 151 proof Black Seal comes from a long, dark line of Bermuda rums. So, unlike most high-octane spirits, it has a deep, rich flavor not overpowered by alcohol burn. Aroma: Sweet dark chocolate, cardamom, and cinnamon. Taste: Herbs, molasses syrup and caramel. Finish: Hint of coffee and tobacco, sweet vanilla.
