First of all, we must understand the contents of the trademark label. As a kind of wine, according to the relevant national regulations, wine bottles must be marked with the following contents: product name, ingredient list, net content, pure juice content, alcohol content, sugar content, factory name, address, production date, shelf life, product standard code, etc. If the label is incomplete or the factory date, factory name and address are not marked, it is a fake and shoddy product.

Secondly, observe the color of the wine. If the wine is clear and transparent, it is a good wine without precipitation and turbidity; On the contrary, it shows that there is something wrong with the quality of the wine. Don't buy it casually.

In addition, we should choose the type of wine from our own hobbies. Wine can be divided into sweet type, semi-sweet type, dry type and semi-dry type according to sugar content, and red, white and pink according to color. High-grade red wine has clear and transparent body, luster, rich and pleasant aroma, soft and pleasant taste, long aftertaste and strong typicality. Generally, the alcohol content of dry red wine is 1 1 degree and 12 degree.

The wine body is slightly reflective under strong light, and the high-quality wine is clear and transparent without turbidity and precipitation; Close to the true color of the original variety of fruit.

White wine should be yellow, green or gold, bright, white and shiny. Any mottled brown indicates poor quality.

Wine should be red, purplish red or pomegranate red, and aged red wine should be ruby red, blood red or dark red, with overall ruddy and transparent. Where the liquid level is dark brown, the quality is poor.

Good quality wine should have rich fruit aroma and rich wine aroma. Fruit aroma comes from the natural aroma of varieties, and wine aroma is formed in the process of brewing and storage. The longer the aging time, the stronger and more lasting the taste of the wine.

Flavored liquor should be fresh, refreshing and pure; Red wine should be dry, mellow, long and round. All tastes are balanced and unified, just right, and the quality that does not match the typical taste is not good.

Packaging Check whether the cork is properly plugged in the bottle mouth. If the bulge is obvious or the bottle has abnormal mucus, it means that it has been damaged during transportation and storage, and the quality of wine will be affected.
