Peter in Florence - Peter in the navy

Gin description

"PETER IN THE NAVY" is a Gin of navy strength. The Royal Navy used to designate as "Navy strength" the Gin that passed this empirical test: if gunpowder remained flammable even after being immersed in the Gin, then the distillate could be safely transported aboard Royal Navy warships. Navy measurement continued until the 1890s and still indicates a distillate with an alcohol content above 57 percent.
