Pusser’s “Gunpowder Proof” is a traditional Royal Navy style rum produced at Admiralty strength and in accordance with the Admiralty’s blending recipe last used when the Royal Navy discontinued its daily ration on 31st July 1970. Prior to the invention of the hydrometer, the ship’s purser shut down claims of watering down sailors’ daily tot by mixing a few grains of gunpowder with the rum to see if it would burn .If the mixture ignited, the rum was “at proof”. If it didn’t, the purser might find himself tossed to sea.
