Velier Royal Navy Tiger Shark Rum is a blend of the best pot-stilled British Caribbean rums. It was created by the famous Italian bottler Velier, led by rum legend Luca Gargano. The average age of the rum used in the Royal Navy Tiger Shark blend is 14 years. The second release in the Velier series dedicated to the British Navy was bottled in 2019 at 57.18%, a reference to the obsolete 100 imperial proof. Before any official measuring systems were introduced, the gunpowder test was used to confirm the alcohol content of rum. To make sure the spirit had not been watered down, it was mixed with gunpowder and then ignited. If the mixture could burn, the rum was rated ‘proof’. 100 imperial proof corresponds to about 57% ABV.
