Official website, Maotai Custom Center introduced that Cordyceps wine belongs to health-care liquor and has a certain shelf life. After the shelf life, it doesn't mean that the quality of the wine will get worse and you can't drink it anymore, but because after the shelf life, the health care effect will be obviously reduced, which is close to ordinary liquor and can't be called health care wine. Therefore, the shelf life of Cordyceps sinensis wine is generally 20 years.
