Strong liquor has changed from grain to wine, and wine is liquid. Hard liquor will naturally freeze when it is frozen. Because when a liquid freezes, it will freeze. Especially if the bottle is too full, it will burst, so you must be careful not to burst when the bottle or jar freezes, which will harm the safety of objects and people.

Jin Jiu's own quality guarantee period is two years. Jin Jiu is a low-alcohol liquor, and relevant medicinal materials have been added. If the bottle cap is unopened and the storage conditions are good, it should still be preserved for a long time, but it is recommended not to exceed five years. Generally, only high-alcohol wine can be stored for a long time, and the sealing condition is good.
In addition, compared with common liquor, health wine contains a variety of Chinese herbal ingredients, depending on the medicinal properties of specific medicinal materials. Some health wines may deteriorate or have a shorter shelf life due to mixing with other ingredients. Chinese herbal medicines such as Chinese yam, medlar, epimedium, astragalus root and angelica are added to Jin Jiu. If the shelf life is over, harmful bacteria such as Escherichia coli and pathogenic bacteria in wine will exceed the standard, which will affect health. Therefore, from the perspective of health care ingredients, the shelf life should still be marked.
