Maotai liquor is a high-end liquor in China, which has high collection and investment value. The collection and investment value of Tian Fei Maotai is not low. Generally speaking, if Moutai is unopened, its value will be higher, because it is easier to keep its original quality and taste if it is well preserved and sealed.
For the opened Tian Fei Maotai, its value will be reduced, but it can still be sold. However, because it has been opened, some consumers may think that the quality is defective or fake, so it is necessary to explain the situation to potential buyers when selling. In addition, if the wine is not well preserved or properly sealed, the taste of the wine may deteriorate, thus affecting its value.
In a word, the opened Tian Fei Maotai can be sold, but it is necessary to explain the situation to potential buyers and pay attention to preserving the wine.
