First look at the outer packaging. Real foreign wine not only has neat and clear trademarks, but also has a strong sense of concavity and convexity, high printing level, and trademark handwriting and patterns will not be vague, outdated and messy.
Second, look at the seal. Wine is very particular about sealing, not only aluminum sealing, but also lead sealing. Some expensive wine containers have lead seals. When the two parties deliver the goods, the lead seal is opened or there is no lead seal, so the wine in this container is equivalent to scrapping.
Third, look at the anti-counterfeiting signs. Each bottle of wine has a trademark on the bottleneck, which is cut open and contains various anti-counterfeiting signs.
Fourth, look at the numbers. Every restaurant has its own password. These Arabic numerals indicate the date of production and when the wine entered the mainland. If the quantity of fake wine does not conform to the numbering procedure of foreign wine shops, it is easy to be seen through.
