A smooth and full-bodied rum, Black Seal Rum is blended by Gosling Brothers of Bermuda. The original recipe 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 I, Black Seal was sold in champagne bottles, the most widely available bottle at the time. The cork was sealed with black sealing wax, hence the name Black Seal. This version of Black Seal rum is bottled at 75.5% abv.
