"In its advertisements and company brochures, the Pierre Smirnoff Co. tells a different story. The Smirnoff company says someone named Ivan Smirnov is believed to have started the business "around 1815" in a "fire-scarred warehouse" in Moscow after the Napoleonic Wars. The company was officially registered in 1818, Smirnoff maintains - hence the "1818" that appears on its vodka bottles."
