How long is the shelf life of medicinal liquor?

According to relevant national standards, beverages and wines with alcohol content greater than or equal to 10%vol can be exempted from labeling the shelf life. Many manufacturers have marked the shelf life of 3 years or 5 years according to consumers' opinions, and some have marked the shelf life of 10 year, which is actually unnecessary. As long as it is well sealed and the storage environment is hygienic, the alcohol content above 10 will not be infected with miscellaneous bacteria. However, if the medicinal liquor is left for too long, too much precipitation and turbidity, then don't continue to drink it.
