Goslings Black Seal Overproof 151 Rum is as high proof as Rum can get. The name even refers to it (75.5% ABV is 151 Proof). Go easy here folks.

The famed Gosling’s Rum! Side note: the name Black Seal came about after WW1, when they began selling their rum in salvaged champagne bottles sealed with a black wax. Customers soon called for ‘Black Seal rum’ and history was made.
