To judge whether a glass bottle is safe, you can consider the following aspects:

1. Integrity: Check the bottle for cracks, gaps or other obvious damage. If there is any breakage, the bottle may break during use or transportation, causing injury.

2. Thickness and quality: Thicker and stronger glass is generally more durable and less likely to break. You can feel the quality of the wine bottle by looking or tapping it gently.

3. Production standards: Choose bottles from reliable manufacturers, who usually follow the relevant production standards and quality control.

4. Use and handling methods: It is also important to use and handle the bottle correctly to avoid violent collisions or improper storage methods.

5. Check marks: Some bottles may have relevant safety marks or certifications, such as compliance with certain international or regional standards.

However, even if a wine bottle appears to be safe, the possibility of accidental breakage cannot be completely ruled out. Always be careful when handling and using glass bottles to minimize the risk. If there are any concerns about the safety of the bottle, it is best to consult a professional or choose an alternative container. In addition, you should also pay attention to moderate alcohol consumption, and follow the principles of safe drinking.
