Smirnoff

Smirnoff vodka is made with water, grain, and yeast. The grain is typically corn, although other grains such as wheat and rye are also used. The water is filtered and often purified before it's used to make vodka. And the yeast is a type of fungus that helps convert the sugar in the grains into alcohol.

Contrary to what you might expect, Smirnoff vodka is not a Russian brand... at least not these days anyway. The brand's roots originate in Moscow by Pyotr Arsenievich Smirnov, but was acquired by British company Diageo back in 2006.
