"Duhuugu" is derived from the Russian word for "water". It is Russia's representative vodka. Initially, it was made from raw materials such as wheat, rye, and barley, which were crushed, cooked, saccharified, fermented, and distilled to produce high-quality alcohol, which was then further processed. There are also some vodkas brewed primarily from potatoes. The manufacturing process of Duhuugu involves diluting high-quality alcohol with water to create an alcohol-water mixture, which is then filtered for the first time, treated with activated carbon, filtered again, and finally adjusted to the specified alcohol concentration, ready for bottling and sale. Generally, no aging is required. By the 18th century, potatoes and corn began to be used as raw materials. The original Duhuugu liquor obtained through distillation undergoes slow filtration for more than 8 hours, allowing the original liquor liquid to be absorbed by activated carbon to capture its flavor. Duhuugu is colorless and odorless, characterized by its neutrality, and does not require storage before it can be sold. Due to its colorless transparency, like gin, Duhuugu can be mixed with other alcoholic beverages to create various mixed drinks.
