Moutai is named after Maotai Town, which is produced on the Chishui River in Zunyi.
Because Maotai Town is located in the river valley, the wind speed is low, which is very conducive to the habitat and reproduction of microorganisms brewing Moutai.
In the 1960s and 1970s, experts from all over the country used Moutai technology and raw materials, pit mud, and even workers and technicians to produce in different places, but the products produced could not achieve the same effect.
It also fully proves that Moutai is closely related to the place of origin, and Moutai cannot be cloned. Therefore, in 200 1 year, Moutai became the first product of China liquor to be included in the geographical protection of its origin by the state.
