1.

Check the bottle with strong light. Illuminate the bottle from the blank between the front and rear labels with a strong hand lamp, especially pay attention to whether there are black spots on the back of the front and rear labels, and pay attention to distinguish the difference between the defective spots and black spots on the bottle. Punching destroyed the original texture of the bottle. No matter what material is filled after punching, when the bottle is irradiated by strong light, small black spots will appear on the bottle. Generally, the position of punching holes is hidden in the black part of the front and back labels, just to avoid this inspection.

2.

Feel the bottle for bumps. Observe the surface of the bottle carefully under the well-lit lamp, focusing on the vicinity of the bottle cap, the base of the heaven and earth cover, the back of the wine label, and the concave part of the font pattern at the bottom of the bottle. Observe and touch the bottle body to see if there are concave and convex points.

3.

After the label is removed, the front and back labels will naturally fall off after soaking in water. In the case of relatively new Moutai, the front and back labels can be completely scraped off with a blade, which will not damage the trademark (non-professionals, please don't imitate it), and you can check whether there are holes in the front and back labels. Maotai, which is usually porous, has long been directly hit on the bottle. It can be directly seen that the current counterfeiting technology is getting higher and higher. They hit the hole in the target, so it is difficult for the naked eye to find it. This bottle belongs to the whole. The whole thing is true. This is the back label. It's true. This is a security label. If you look at it with a magnifying glass, the whole bottle of wine is fine. It's all true. But everyone must pay attention to this position. Where there is a black line, if you use a strong flashlight, you can't see that it has been punched. Let's have a look. We scraped the label open with a blade and obviously found two small holes, which could not be photographed with such a flashlight. How did we find it? If you feel good when you touch it with your hands, you can feel uneven, because this hole is filled with soft glue. If you touch something like this with soft glue, it will feel concave and convex. If you block them with anhydrite, it will be hard to find them by hand.
