1. Keep your eyes on the package and touch six sides. When buying wine, we must carefully and comprehensively examine the brand name, color, pattern, label, bottle cap, bottle, certificate of approval, gift box and other aspects of the wine. The printing of labels of good liquor is very particular; Excellent white paper, clear font specifications, bright and uniform color, accurate pattern matching, and non-overlapping ink lines. The edge seams of genuine packaging are neat and tight, and there is no uneven tightness and gaps.

2, open the box to take things, check the bottle cap. Recently, most of the famous liquor bottle caps in China use aluminum metal anti-theft caps, which are characterized by smooth body, uniform shape, convenient opening, neat and clear patterns and characters on the caps, and tight matching. If it is a counterfeit product, it often drips out when it is turned upside down, and the lid is not easy to twist off, and the pattern and text are blurred.

3. Turn the bottle upside down. If it is packed in a colorless transparent glass bottle, hold the bottle in your hand, turn it upside down slowly, and observe the bottom of the bottle against the light. If there are sunken substances or cloud-like phenomena, it means that there are many impurities in the wine; If the liquor does not lose luster, turbidity and suspended matter, it means that the quality of the liquor is better. From the color point of view, except for Maotai-flavor liquor, general liquor should be colorless and transparent. If the wine is packaged in porcelain bottles or colored glass bottles, shake it slightly and open it, and observe its color and sediment as well.

4. Pour the wine into the glass, and smell it to distinguish the taste. Pour the wine into a colorless and transparent glass, and observe it in natural light. The liquor should be clear and transparent, without suspended matter and sediment; Then smell its aroma and put your nose close to the mouth of the cup to distinguish the level and characteristics of the aroma; Finally, taste the taste, drink a small amount of wine and spread it on the tongue surface to distinguish the thickness, softness, alcohol and roughness of the taste, whether the sour, sweet, sweet and spicy are coordinated, and whether there is a aftertaste. Wuliangye, brewed from sorghum, glutinous rice, rice, wheat and corn, has a long aroma, mellow taste, sweet mouth, clean throat, harmonious tastes and just right taste, which is the first-class taste experience of liquor. Low-grade and inferior liquor is generally made of poor quality or moldy grain, which is rough in technology, choking and hurting the head when drinking.

5, wine is warm and angry, and oil drops sink to the bottom. Put a few drops of white wine in the palm of your hand, then cross your hands to make the two palms contact and rub hard for a few times. If the wine smells fragrant after heating, it is a high-quality wine; If the smell is sweet, it is a mid-range wine; Bitter and smelly, it is inferior wine.
