Background

The fermented glutinous rice is called fermented glutinous rice or sweet wine. Carignan is called as carignan in old times, is brewed by glutinous rice, is a traditional special wine in Han nationality, and is called as Jiang Rice wine as a main raw material. The fermented glutinous rice is generally called as rice wine or sweet wine in the north, and is prepared by mixing steamed glutinous rice (glutinous rice) with wine yeast (a special microorganism yeast) and fermenting. The brewing process is simple, and the taste is fragrant, sweet and mellow. The alcohol content is extremely low, so the wine is deeply loved by people. China uses high-quality coarse glutinous rice to brew wine, and has a long history of more than one thousand years. Rice wine has become a beverage for peasant families to drink daily, and modern rice wine is produced industrially.

The prior fermented glutinous rice needs to be stored in a refrigerator at low temperature when being stored after brewing, and the storage environment is harsh, so the fermented glutinous rice cannot be stored at normal temperature and is inconvenient to carry.
