Vodka (Polish: wódka, Russian: ?????) is a distilled beverage composed primarily of water and ethanol, sometimes with traces of impurities and flavorings. Vodka is made by the distillation of fermented substances such as grains, potatoes, or sometimes fruits or sugar.
Traditionally prepared vodkas had an alcoholic content of 40% by volume.[citation needed] Today, the standard Russian, Ukrainian, Estonian, Polish, Latvian, Lithuanian and Czech vodkas are 40% alcohol by volume (ABV) or 80 proof. The European Union has established a minimum of 37.5% ABV for any "European vodka" to be named as such. Products sold as vodka in the United States must have an alcoholic content of 30% or more. For homemade vodkas and distilled beverages referred to as "moonshine", see moonshine by country.
In some countries, black-market or "bathtub" vodka is widespread because it can be produced easily and avoid taxation. However, severe poisoning, blindness, or death can occur as a result of dangerous industrial ethanol substitutes being added by black-market producers. In March 2007 in a documentary, BBC News UK sought to find the cause of severe jaundice among imbibers of a "bathtub" vodka in Russia. The cause was suspected to be an industrial disinfectant (Extrasept) - 95% ethanol but also containing a highly toxic chemical - added to the vodka by the illegal traders because of its high alcohol content and low price. Death toll estimates list at least 120 dead and more than 1,000 poisoned. The death toll is expected to rise due to the chronic nature of the cirrhosis that is causing the jaundice. However, there are also much higher estimates of the annual death toll (dozens or even hundreds thousand lives) produced by the vodka consumption in Russia.
