1. First of all, the most important use of these two glass beads of Moutai is "anti-counterfeiting".

2. Secondly, the second function is sealing. The gap between the two glass beads is very small, which can seal the bottle mouth more tightly and prevent the smell of wine from emitting. Maotai liquor is an old wine, and the longer it is stored, the more mellow it becomes, while the liquor volatilizes slowly. Glass beads can slow down the launching process and make it better sealed.

3. Finally, control the pouring flow. Maotai's cups are very small. The earliest ones are 15ml, and some are 10ml. The advantage of a small cup is that it can gather the fragrance of wine, and it is more soothing and comfortable to sip it. In order to prevent the wine from overflowing when pouring, these two glass beads are added to control the pouring flow.
