Self-brewed sorghum liquor is preserved with 1573.

About 70% humidity preservation. National pits 1573 can be stored for a long time, and the humidity of about 70% is the best. If it is too wet, the cork and wine label will rot. If it is too dry, the cork will dry and lose its elasticity, and the bottle mouth will not be tightly sealed. When sorghum liquor is stored, sealing film or wax is used before storage, which greatly reduces the chance of liquor escaping.
