Vodka's birthdayPhoto:RussianLookIn his work, the chemist studied the specific gravity of alcohol and water solutions depending on their concentration and temperature. The water-alcohol mixture with the desired concentration of 33.4% by weight or 40% by volume is discussed in the fourth and fifth chapters of the dissertation: "On the greatest compression that occurs during the mutual dissolution of anhydrous alcohol and water" and "On the change in specific gravity when alcohol combines with water". Many myths and legends are associated with Mendeleev. For example, there is a legend that a scientist developed a recipe called "Moskovskaya Osobnaya", later "Moskovskaya Osobaya", which in 1894 was patented by the Russian government as Russian national vodka. In fact, this strong drink, or polugar, was widespread in Rus' as early as the 16th century. The word "vodka" first appeared in an official document on June 8, 1750, in the decree of Empress Elizabeth I "Who is allowed to have stills for moving vodkas". However, for a long time, the names "hot, simple, table wine", "pennik", "polugar" or "moonshine" appeared in trade records and government acts. The quality of vodka was checked as follows: if the volume decreased by half when burned, then you were holding real gold, not alcohol with water. Recently, the lead singer of the group "VIA Gra" became the face of vodka. The sexy singer allowed her image to be placed on the label of the alcoholic drink.
