The traditional brewing method of vodka is that firstly, potatoes or corn, barley and rye are used as raw materials, and the alcohol content is as high as 96% by distillation, and then the alcohol content flows through a container containing a large amount of charcoal.

In order to absorb impurities in the liquor (every 10 liter of distilled liquor should be continuously filtered with 1.5 kg charcoal for at least 8 hours, and at least 10% charcoal should be replaced after 40 hours), and finally diluted with distilled water to an alcohol content of 40-50%, so as to remove toxins and other foreign substances contained in the alcohol.

Vodka can be sold and drunk without aging, and a small amount of vodka, such as fragrant vodka, has to go through a fragrant process after dilution to make it fragrant. Vodka, like gin, is a strong drink with high alcohol content based on grain and does not need to be aged.
