It's easy to identify. Each batch of crooked mouth lang bottle caps has anti-counterfeiting labels on the side. Opening the bottle cap will destroy the security label. This anti-counterfeiting label is made with reference to RMB, and it will be uneven to the touch. There is a gold thread embedded in the middle of the label.
Because anti-counterfeiting labels require high technical costs, counterfeiters will not spend so much money to make them, so they can be recognized almost at a glance.
In addition, there are some identification methods on the Internet, and it is not advisable to make a fuss about fonts and packaging colors. Different batches of wine may have different packaging colors and different fonts on wine bottles. For example, after the new Trademark Law of 20 14 was promulgated, all the well-known trademarks written on the original bottles of Langjiu were changed to Sichuan Gu Lin Langjiu.
