Went into Chelsea Wine and Spirits for a bit of a Gin Tasting. This English Gin is 114 proof. This gin used to travel with the British Navy and is called Navy Proof because 114 proof with not effect gun powder if spilled on it. This is were Navy Proof comes from. We were told this by the guy in charge of the tasting. They used to lock up the Gin in the same room as the gun powder on all British Naval Vessels. It was pretty strong and really good.
