Goslings Black Seal Rum is blended by the Gosling Brothers of Bermuda. It's both a full-bodied and smooth. The recipe for the rum is a closely guarded family secret that has been handed down for over four generations. Originally called 'Old Rum' it was available only on draught, out of oak barrels. Finally, after World War One, Goslings Black Seal was sold in champagne bottles. Sounds strange, but champagne bottles were the most widely available bottle at the time. The cork was sealed with black sealing wax, hence how it acquired it's current name Black Seal.
