According to the General Standard for Food Labeling, foods with a shelf life of more than 18 months but less than 7 days may not be marked with a shelf life or a shelf life date. At present, there is no mandatory requirement for the shelf life of liquor in China, but this does not mean that the longer the liquor is stored, the better. After five years, the taste of ordinary aromatic liquor will be weakened and the flavor will be weakened. Maotai-flavor aged wine is a good wine, but whether Luzhou-flavor wine stored for many years is a good wine is still inconclusive and controversial. There are two basic concepts to be clarified here, that is, the difference between the storage period and the shelf life of liquor. Whether it is XO, remy martin, Louis XIII or aged Maotai, its storage period is actually an integral part of its production process; Shelf life refers to the quality guarantee period of products in packaging after leaving the factory. It is futile to talk about things with shelf life, because long-term storage is an important part of Moutai production technology. Some Luzhou-flavor liquor enterprises don't understand this truth, and they still use the banner of aged liquor, which leads to the problem of liquor shelf life. Luzhou-flavor liquor does not have and cannot have long-term storage technology.
