Whether bottled mineral water can be drunk after expiration depends on the expiration time and storage conditions. Generally, the expiration time of bottled mineral water is about 2 years. However, if there are problems such as high temperature, direct sunlight, and broken bottles during storage, the quality of mineral water will be affected and the expiration time will be shortened.
If bottled mineral water has expired, we can judge whether it can still be drunk from the following aspects:
1. Observe the appearance of the bottle: if the bottle is damaged, deformed, discolored, etc., then the water inside may have been contaminated and can no longer be drunk.
2. Smell: if the mineral water has peculiar smell or moldy smell, it can't be drunk any more.
3. Tasting: If the feeling of the mineral spring mouth becomes worse, or there is a peculiar smell, you can't drink it again.
In general, bottled mineral water may be drinkable if it has a short expiration time and good storage conditions. However, if the expiration time is long or the storage condition is poor, it is not recommended to drink again, because it may affect health. The best way is to drink up the mineral water before the expiration date, or choose fresh mineral water when buying.
