1. Communicate with the store: First of all, you can communicate with the store and ask them how to prove that this is really Moutai. Ask the store to provide relevant certificates or documents to prove the authenticity of this bottle of wine.
2. Seek the help of a third-party organization: If you can't reach an agreement with the store, you can seek the help of a third-party organization, such as the relevant alcohol appraisal organization or the authoritative consumer rights protection organization. They can test and identify this bottle of wine to determine whether it is really Moutai.
3. Contact the consumer association: If the above two steps can't solve the problem, you can contact the local consumer association for help and advice. They can provide you with relevant legal support and rights protection guidance.
When dealing with this situation, remember to be calm and patient, don't trust the store's words easily, and don't give up your rights easily. At the same time, it is suggested that when buying high-grade liquor such as Maotai liquor, we should choose formal purchase channels to ensure the authenticity and quality of the goods.
