In order to achieve the purpose of confusing the fake wine with the real one, the fake wine is often labeled with the name of the factory with the same pronunciation as the real wine, such as "LU ZHOU LAO JIAO CO.,LTD Co., Ltd. Qujiu". Real wine is labeled as a whole bottle, with four small characters of "LU ZHOU LAO JIAO CO.,LTD Co., Ltd." and three big characters of "Tequ Liquor" in the middle, and a round trademark pattern and color composed of wheat ears in the middle.

The words "Luzhou Qu Winery" are printed on the sealant sleeve of the bottle cap. The words "China Luzhou Qu Factory Special Qu (Touqu)" are printed on the metal security cover. Fake wine has no sealing rubber sleeve, even if real bottles are used, it can be identified by this method. In addition, it can be distinguished from the old and new procedures of trademarks.

A really good-tasting wine has four characteristics: rich aroma, mellow taste and sweet aftertaste. After opening the bottle and unplugging it, the fragrance is elegant and the charm is endless. After drinking it, it is fragrant after hiccups and choking, which is not easy to get on the head. Especially, the aftertaste after drinking has a special fruit aroma, which is refreshing. Fake wine is mostly inferior, turbid and precipitated, and its taste is different from real wine.
