Navy Strength Gin

“Navy Strength” is not a separate style — it is a strength category. Any gin bottled at 57% ABV or higher can be labeled Navy Strength.

The origin story is naval: British Royal Navy ships carried gin (and rum) alongside gunpowder in the ship’s hold. If a barrel leaked into the gunpowder, the powder had to still ignite. Only spirits above roughly 57% ABV would allow soaked powder to burn — that’s the historical “proof.” This ratio, 57.15%, is the reason for the number.

Why does this matter at the bar today?

• Bolder flavor. Higher ABV means botanicals push harder through mixers, so a Navy Strength gin cuts through tonic, citrus, or heavy cocktails without disappearing.
• Cocktail integrity. In stirred drinks like a Martini, Navy Strength can give a bigger, drier profile.
• Distinct label cues. Classic examples: Plymouth Navy Strength, Hayman’s Royal Dock, Perry’s Tot.

Remember: Navy Strength is a strength; the underlying style (London Dry, Old Tom, Contemporary) is separate. A brand may make both a standard London Dry and a Navy Strength London Dry from the same botanicals.
