Black Powder, Tanglin’s Navy Strength Gin, is a punchy 58% ABV making it an ideal Cocktail gin, but still super smooth for sipping. Why Black Powder? Centuries ago, a Chinese Alchemist was searching for the Elixir of Life. Ironically he created gunpowder instead and called it Black Powder. Navy Strength Gin has to be above 57% ABV, the strength at which Gin drenched gunpowder still ignites when lit. Navy's often provided rations of Gin, so this test was frequently used to check against unscrupulous employers. A crafty solution to ensuring a great drink.
