The traditional term Navy Strength refers to the high ABV of gin. Its the proof at which gunpowder would still ignite, should gin be spilt on it, and was the established way British Navy officers would test the strength of their gin supplies, ensuring that they were not diluted by unscrupulous suppliers, or indeed by fellow sailors. 57% is the proven ABV of NB Navy Strength, a gin with strength of character and intensity of flavour.
