1. Look at the bottle shape. Many famous brands of liquor have unique bottle shapes. For example, Moutai has been using white cylindrical glass bottles for many years, with a smooth bottle body and no impurities; Luzhou Laojiao Tequ uses a colorful bottle with the words "Luzhou Laojiao Distillery Patented Bottle" on the bottom of the bottle. Fake wine has bottles of varying heights and thicknesses, the outer packaging is old and lacks freshness, and the sealing is not tight or the teeth are not neat.
2. Look at the printing. The printing of good liquor labels is very particular; the paper is fine and white, the fonts are clear and standard, the color is bright and even, the pattern registration is accurate, and the ink lines do not overlap. If there are English or Pinyin letters, the size should be consistent. In addition, many brands of liquor now use laser anti-counterfeiting marks on their packaging boxes or bottle caps. For example, Maotai liquor has two types of anti-counterfeiting patterns: "Flying Sky" and "Five-Pointed Star". They will show different colors when viewed from different angles, and only It can be used once and cannot be restored if it is slightly damaged.
3. Look at the bottle caps. Recently, most of the bottle caps of famous liquors in my country use aluminum metal anti-theft caps. They are characterized by smooth cap body, uniform shape, easy opening, neat and clear patterns and words on the cap, and matching tight. If it is a counterfeit product, it often leaks out when turned upside down, the cover is not easy to twist off, and the pattern and text are blurred.
4. Look at the packaging. In addition to the exquisite printing, the paper cap packaging of real wine has neat and tight edge seams, with no gaps left by uneven tightness; some bottle caps are also wrapped with plastic film. The packaging is very tight and there is no looseness.
5. See the clarity and turbidity. From the appearance of the glass bottle, the liquor should be absolutely clear and transparent with no precipitation. The clearer and more transparent the better. You can hold the wine bottle in your hand, slowly turn it upside down, and observe the bottom of the bottle to see if there is any sinking material or cloud-like phenomenon. As a general rule, if the hops are evenly distributed, the density gap is obvious, and the hops slowly disappear, and the wine is clear and transparent, it is a high-quality wine.
6. Smell the aroma. One way is to pour a little less wine on your hands, rub it with both hands for a while to heat the wine, and then smell its aroma. Generally speaking, if the wine smells fragrant, it is a fine wine; if it smells sweet, it is a medium wine; if it smells bitter, it must be a fake wine. Another method is to add a drop of cooking oil to the wine and see how the oil moves in the wine. If the oil spreads evenly in the wine and sinks evenly, the quality of the wine is good; if the oil diffuses irregularly in the wine and the sinking speed changes significantly, it is certain that there is a problem with the quality of the wine.
