Vodka
The origin of vodka (and its name) is Polish, although its authorship is attributed to Russia. It consists only of water and ethanol, except for insignificant amounts of botanicals. It is usually produced by fermenting grains and other plants rich in starch, such as rye, wheat or potatoes. Normally the alcohol content is between 37% and 50% of the volume.
The intention, apparently, was to achieve a concentration of alcohol so high that the product could not freeze easily, since alcohol freezes at lower temperatures than water. However, it was the famous Russian chemist Dmitri Mendeléiev who established that the best alcoholic degree for vodka is 40 degrees, and as a demonstration of his scientific model, he created the Moskovskaya vodka formula, considered as a model vodka. The formulas of Stolichnaya and Moskovskaya are part of the National Treasury of Russia.
