What is the liquor with adult sauce in the middle of the liquor carton?

A: Aged Maotai-flavor wine is an adult wine, also called vintage wine. It refers to the liquor of a certain year, usually starting in 3 years, and there is no upper limit, so it is called vintage wine. Because the older the liquor, the more fragrant it is, and the longer it takes, almost all the substances contained in liquor evaporate, resulting in a large amount of ethyl ester, that is, aroma. Therefore, the higher the vintage, the stronger the aroma. But relatively speaking, the price of aged wine is naturally higher. After a certain period of storage and long-term synthesis, vintage wine will become soft in quality, and in addition, it will produce some aroma, which will make people drink more mellow and memorable.
