#What Is Vodka? From its humble medieval origins as a medicinal agent vodka has conquered the world. In 2012 tipplers downed 1. 17 billion gallons (4. 44 billion liters) of the distilled alcoholic beverage making it the world's most popular spirit. But what is made vodka from? To produce vodka you must first ferment any foodstuff that contains sugar or starch then distill the product to increase its alcohol content. Fermentation means feeding sugar to yeast so that the yeast can produce alcohol. Today most vodka is made from fermented grains such as sorghum corn rice rye or wheat though you can also use potatoes fruits or even just sugar. The fermentation step creates a product with only about 16 percent alcohol by volume (ABV) too low for spirits. Upping that number requires distillation or heating in a container called a still. Because alcohol boils at a lower temperature than water you can collect the evaporated alcohol separating it from the water. Most vodka is 30 to 40 percent ABV. Rectified spirits like the American brand Everclear reach 95 to 96 percent ABV. The first records of vodka come from ninth-century Russia and eighth-century Poland. Vodka's popularity spread with Russian soldiers during the Napoleonic wars After the Russian revolution one vodka maker relocated to Paris and started a distillery under the now-famous French spelling of his name: Smirnoff.
