1. Look at the trademark: the genuine product is registered as a full bottle sticker. Marked by the striking three cursive characters of Wuliangye, the bottom of the pattern is set off with yellow ears of grain, and all the ears of grain are covered with red. The graphics of Wuliangye and Gusui are embossed, and the factory date is printed on the back of the trademark, which can be seen clearly through the wine bottle. Counterfeit trademarks: the trademarks are messy, including Seiko brand and Baiyunshan brand, and some have no registered trademarks at all, and the origin is messy. Trademark colors and fonts are different, and trademark printing is rough with flat printing.

2. Look at the bottle type: genuine bottle type: there are two types: drum type and wheat ear type, and the name of the fired factory is on the bottle; The bottom of the bottle is round, with a convex triangle in the center and regular protruding stripes around it. The bottle cap is a metal cap, and the bottle cap is separated from the inner cap. Authentic glass is made of high white material or ordinary white material, with elegant shape, white and transparent glass, uniform and exquisite overall, no bubbles and wrinkles, and clear and correct fonts on the bottle. Fake bottle types: square, cylindrical, etc., the bottom of the bottle has no convex triangle, and the bottle cap is mostly plastic. The fake wine bottle is rough, with wrinkles and bubbles, and the words on the bottle are not clear.

3. Look at the bottle cap: the genuine Wuliangye bottle cap is made of a metal twist-off cap, which is golden in color and has a good finish. The factory emblem pattern is printed on the top of the cap, and the surrounding fonts are clear and correct, and the lock is flat and smooth. There are two anti-counterfeiting measures at the top of the bottle cap: one is lithography, and the other is invisible code spraying. Since January 1, 1994, dark spraying has been used on drum-shaped and crystal-shaped Wuliangye bottles. Under the irradiation of ultraviolet light, the blue factory emblem pattern and W·L·Y (the abbreviation of Wuliangye Chinese pinyin) can be seen. The whole pattern has uniform color, clear lines and clear outline, and is not broken. Fake Wuliangye bottle cap: the pattern and text are incorrect, the production is rough, the aluminum material used is thin, the color is dim and the finish is poor. The level of locking technology is low, uneven and smooth, and some even have concave marks caused by hard object extrusion.

4. Look at wine quality: authentic wine quality: crystal clear and transparent, with long-lasting aroma and sweet taste. In addition to 6 Wuliangye, there is 38 Wuliangye, which retains the original 6 characteristics of fragrance, sweetness, alcohol and purity. Fake wine quality: the wine is slightly turbid and pungent when smelling. When tasting, it is choking, violent and spicy, with obvious bitterness.
