There are several aspects to determine the authenticity of wine:

1. Product channel reliability: When purchasing genuine wine, it is usually recommended to choose officially authorized sales channels or regular retailers.

2. Product packaging and logo: The packaging of genuine wine usually has higher printing quality and complete logo/trademark.

3. Commodity price: Be wary of wine that is too low-priced, especially if it is lower than the market average price, as it will be a fake and shoddy product.

4. Authenticity query: Some brands will provide authenticity query services, and you can confirm the authenticity of the product by querying the batch number or other relevant information.
