Friends who have drank Moutai’s wine all know that there are two glass beads at the Moutai wine bottle. The glass is high and the purity is called glass crystal, also known as artificial crystal.

Method/step.
Because Moutai Town lives in the inland, the transportation of Moutai is very troublesome. Adding beads to the bottle mouth can effectively prevent large -scale leakage in transportation.
Small glass beads and small glass beads will reduce the flow of wine and avoid unnecessary waste caused by excessive alcohol.
And the wine falls slowly, and the time to wait for the wine is longer. You can have more time to chat and create a pleasant drinking atmosphere.
Moutai wine is mellow and rich, with glass beads blocked, which can reduce the contact area between wine and air and prevent wine from exuding.
With the barrier of beads, it is difficult to add fake wine directly. There are too many people who have fake wine now, and even Moutai wine bottles have risen. 53 degrees flying Moutai empty bottle without damaging the beads in the bottle can be sold for 200 yuan. It can be seen that this little bead is also a very important existence in the process of making fake wine.

Precautions.
Warm reminder: If you ca n’t fall out of the wine, first shoot with your palms at the bottom of the bottle, because of the weather, this bead will be attracted by the air. After Moutai was completely ca n’t come out, throw away the bottle, pry open the bottle mouth, take out two glass beads, and pour out Moutai’s small cup with co -marking wine.
