as far as I know, the preparation process is a common process for brewing plum wine in many large factories, which can make the taste more stable and is easy for mass production.

Plums in Puning, Guangdong Province, the hometown of plums used as raw materials for plum wine, are famous for their small nuclei and high acidity. Picking fresh plums for 72 hours and treating them with sugar pickling process for more than 9 days, the obtained plum juice is fresh and healthy, and it is made from pure sorghum wine in Tongjiangji winery. The taste is refreshing and sweet, and it tastes very good with ice.
