The ancient brown sugar is a lump brown sugar, which is boiled by the traditional "straight wind stove" or "chain pot", which is obviously different from the common granular brown sugar. It crystallizes fructose, reducing sugar, glucose, molasses, vitamins and mineral trace elements in sugarcane, which is a mixture and a multi-element sugar. The ancient brown sugar is produced in the original ecological mountain area, and it is made by hand boiling fresh sugarcane at the altitude of 1 100 meters in Yunnan-Guizhou Plateau after 18 processes.

Brown sugar refers to the finished sugar of sugar cane with honey, which is formed by squeezing and concentrating sugar cane. Brown sugar is divided into flake sugar, brown sugar powder, bowl sugar, etc. According to different crystal particles, because it has not been highly refined, it contains almost all the ingredients in sugarcane juice. Besides the functions of sugar, it also contains vitamins and trace elements, such as iron, zinc, manganese, chromium, etc., and its nutritional components are much higher than those of white sugar. Famous brown sugar producing areas are Gongcheng Yao Autonomous County in Guilin, Guangxi, Yunnan and so on.
