Bottled water can generally remain drinkable for an extended period if stored properly. While most bottled water comes with a "best by" date, it can last indefinitely if unopened and kept in a cool, dark place away from chemicals and strong odors. However, for optimal taste and safety, it’s advisable to consume it within two years of purchase.
How Long Does Bottled Water Stay Safe to Drink?
Bottled water does not spoil in the same way that food does, but its quality can degrade over time. The plastic bottles used for packaging can affect the water’s taste and safety. Over time, chemicals from the plastic may leach into the water, especially if stored improperly.
Factors Affecting Bottled Water Shelf Life
-
Storage Conditions: Keep bottled water in a cool, dark place. Avoid direct sunlight and heat sources, as these can accelerate chemical leaching.
-
Bottle Material: PET (polyethylene terephthalate) bottles are commonly used for bottled water. While safe, they are not designed for long-term storage. Glass bottles, while less common, do not have this issue.
-
Exposure to Chemicals: Store bottled water away from chemicals and cleaning agents to prevent contamination.
How to Store Bottled Water Properly
To ensure your bottled water remains drinkable and safe, follow these storage tips:
- Keep bottles sealed until you’re ready to drink them.
- Store in a cool, dark place to prevent heat exposure.
- Avoid freezing water bottles, as this can cause the plastic to crack and potentially leach chemicals.
Does Bottled Water Expire?
Bottled water does not have an expiration date in the traditional sense. Instead, it has a "best by" date, which is more about maintaining quality than safety. This date is usually set by manufacturers to ensure the best taste.
Understanding "Best By" Dates
- Taste and Quality: Water may start to taste different after the "best by" date due to plastic leaching.
- Safety: As long as the bottle remains sealed and stored properly, it remains safe to drink.
Practical Tips for Managing Bottled Water
- Rotate Stock: Use older bottles first to ensure you’re consuming them before any potential decline in quality.
- Check for Damage: Before drinking, inspect bottles for cracks or leaks, which could indicate contamination.
- Taste Test: If the water tastes off, it might be best to discard it.
People Also Ask
How Can You Tell if Bottled Water Has Gone Bad?
While bottled water doesn’t spoil, it can develop an off taste or smell if stored improperly. If the water tastes or smells unusual, it might be best to discard it.
Is It Safe to Drink Bottled Water Past the Expiration Date?
Yes, it is generally safe to drink bottled water past its expiration date if it has been stored properly. The date is more about quality than safety.
Can Bottled Water Be Stored in a Hot Car?
It’s best to avoid storing bottled water in a hot car for extended periods. Heat can cause the plastic to degrade, potentially leaching chemicals into the water.
Why Does Bottled Water Have an Expiration Date?
The expiration date is primarily for quality assurance. It indicates the period during which the manufacturer guarantees the best taste and quality.
What Is the Best Way to Store Bottled Water for Emergencies?
For emergency storage, keep bottled water in a cool, dark place. Ensure the bottles are sealed and periodically rotate your stock to maintain quality.
Conclusion
While bottled water can remain drinkable indefinitely if stored correctly, it’s wise to consume it within two years for the best taste. Proper storage is crucial to prevent chemical leaching and maintain quality. By following these guidelines, you can ensure your bottled water remains a safe and refreshing option for hydration.
