Expired water is generally safe to drink. While the expiration date on bottled water indicates when leached chemicals may start to affect the water's taste, it's unlikely to make you sick, especially if the water has been stored properly.
- Water is a stable compound: Pure water doesn't contain nutrients or calories for bacteria to feed on, making it resistant to spoilage.
- Expiration dates are more about taste: The expiration date is mainly a guideline for when the water may start to taste different due to chemicals leaching from the plastic bottle.
- Proper storage is key: Storing bottled water in a cool, dark place can help to extend its shelf life and minimize the risk of contamination.
However, while drinking expired water is usually safe, it's best to err on the side of caution and use bottled water before its expiration date for optimal taste and quality.
