Because food-grade plastic packaging materials mainly include polyethylene plastic and polyester plastic.

Using ordinary polyethylene plastic barrel liquid, especially liquid with high alcohol content, polyethylene will be dissolved by alcohol. The longer it takes, the more it dissolves. Drinking this wine may cause skin allergies.

Polyester plastics are not as airtight as glass bottles and are not suitable for long-term storage. Plastic is full of liquid, and alcohol is a good organic solvent, in which some components of plastic will dissolve.

Observation packaging

When buying wine, we must carefully and comprehensively inspect the brand name, color, pattern, label, bottle cap, bottle body, certificate, gift box and other aspects of the wine. The label printing of good wine is very particular; Excellent white paper, clear font specifications, bright and uniform colors, accurate pattern matching and no overlapping ink lines. The side seams of genuine packaging are neat and tight, and there are no uneven tightness and gaps. Do not buy liquor without the name, address and production date of the factory.

Check the bottle cap

At present, most of the well-known liquor bottle caps in China use aluminum metal anti-theft caps, which are characterized by smooth bottle body, uniform shape, convenient opening, neat and clear patterns and characters on the bottle caps and close cooperation. If it is a counterfeit product, it will often drip out when it is turned upside down, and the cover is not easy to unscrew, and the pattern text is blurred.

Observation quality

If it is in a colorless and transparent glass bottle, hold the bottle in your hand, turn it upside down slowly, and observe the bottom of the bottle in the light. If there are sunken substances or cloud-like phenomena, it means that there are many impurities in the wine; If the liquor has not lost its luster, turbidity and suspended matter, it shows that the quality of liquor is better. From the color point of view, except for Maotai-flavor liquor, general liquor should be colorless and transparent.

Smell and distinguish the taste.

Pour the wine into a colorless and transparent glass and observe it in natural light. Liquor should be clear and transparent, without suspended matter and sediment; Then smell its aroma, put your nose close to the mouth of the cup, and distinguish the level and characteristics of the aroma; Finally, taste it, drink a small amount of wine, and apply it on your tongue to distinguish the thickness, softness, alcohol content, roughness and whether the sour, sweet, sweet and spicy tastes are harmonious. However, low-grade inferior liquor generally uses inferior or moldy grain as raw materials, and the process is rough, which makes people choke and head.
