Navy Strength Gin

The Royal Navy stored gunpowder and spirits in close proximity aboard ships. If gin leaked onto gunpowder, the test was whether the gunpowder would still ignite — it would at 57% ABV (100 proof) but not below, where water concentration prevented ignition. This made 57% a practical minimum proof for Navy supply, and provided a built-in anti-adulter test: if the purser watered down rations, the gunpowder caught him.

Flavor Profile

Contains roughly 42% more alcohol by volume than standard gin. Botanical profile is more concentrated and intense — juniper bolder, citrus brighter, spices more present. Punches through dilution and carbonation more effectively. In a G&T, maintains botanical character as ice melts when standard-strength gin would fade.

No dedicated EU legal category — Navy Strength gin must still meet the requirements of whatever tier it's produced as (usually distilled gin or London Dry). The term 'Navy Strength' is a marketing designation, not a legal one. The standard is 57% ABV (100 degrees proof on the old English scale). The '57% ABV' designation was formalized as a marketing category in the 1990s, though the 57% standard itself has historical roots.
