Nerabus Heather Navy Gin 57%

The British Royal Navy would often keep their gin on board their vessels below deck where they also stored their gunpowder. To ensure that the merchants providing the gin were not selling diluted spirits. It is thought that they would test out how strong their gin was by testing it on a small sample of gunpowder soaked in spirit. If the gunpowder didn’t light then the gin had been diluted down, if the gunpowder still lit then they knew that the gin was at least 57% abv (114 proof); it became therefore known as Navy Strength Gin.
