The label printing of good liquor is very particular: the paper is excellent white, the font specifications are clear, the colors are bright and uniform, the pattern colors are accurate, and the ink lines do not overlap. If there are English or pinyin letters, the sizes and specifications are the same. If you don't have one of the above characteristics, you can conclude that it is fake wine and inferior wine.

In addition, there are many brand-name liquors that use laser holographic anti-counterfeiting marks on the packaging boxes or bottle caps, such as Maotai liquor, whose anti-counterfeiting patterns are "Tian Fei" and "Five-pointed Star", which will appear in different colors from different angles and can only be used once, and can not be recovered after minor damage.

The trademark logo of fake wine is rough, the color is incorrect and the pattern is fuzzy, which is obviously different from the trademark logo of real famous brand wine. From the appearance through the glass bottle, liquor should be absolutely clear and transparent without precipitation. The clearer and more transparent the better. You can hold the bottle in your hand, turn it upside down slowly, and observe the bottom of the bottle to see if there is any sinking substance or cloud phenomenon.

According to the convention, if hops are evenly distributed, the gap between the density of hops is obvious, hops slowly disappear, and the wine body is clear and transparent, it is a high-quality wine. If the liquor is turbid and has floating impurities, hops will turn up densely, distribute unevenly and disappear soon.
