Gowasu originated in Russia and has a history of 1000 years. According to some records, when Russian aristocrats travel to Paris and live in their charming upper class, they will feel pain because there is no Gowasu there, and even go home.
Gowasu/Kvas (Russian, Ukrainian: квас, meaning "fermentation"; Polish: kwas chlebowy, meaning "fermented with bread"; Lithuanian: Gila; ; Estonian: kali) is a low-alcohol beverage, which is very popular in Russia, Ukraine and other eastern European countries. Fermented with dry bread, the color is similar to that of beer but slightly red, with moderate sweetness and sourness.
Because its alcohol content is only about 1%, children can also drink it, and it is a very popular soft drink. In addition, in Russian cities, Kvas can also refer to black tea and fungus. This drink was introduced to Harbin, Jilin, Yili, Tacheng and Urumqi in Xinjiang.
