1. When purchasing red wine, you should understand the content of the trademark label, including product name, ingredient list, net content, pure juice content, alcohol content, sugar content, factory name, factory address, production date, shelf life, product Standard code, etc. In addition, consumers should try their best to purchase pure juice wines with grape varieties labeled, as the quality of such wines is more guaranteed.

2. Observe the color of the wine. If the whole body is clear and transparent, showing deep ruby ??red, and there is no precipitation or turbidity, it is a good wine; if the color is dark, without luster and brightness, it means there is a problem with the quality of the wine, and consumers should buy it with caution.

High-end white wine is generally slightly yellowish with green color, clear, transparent and shiny, with a fruity and pleasant aroma, and the alcohol content is generally around 12 degrees.
