Water bottles, especially those made of plastic, don’t have an expiration date in the traditional sense. However, the quality of the water and the container can degrade over time. Typically, unopened bottles of water can last indefinitely if stored properly, but for best taste and safety, it is recommended to consume them within 1-2 years.
How Long Can You Store Unopened Water Bottles?
Unopened water bottles can last a long time, but their longevity depends on several factors, including storage conditions and the material of the bottle. When stored in a cool, dark place, away from direct sunlight and chemicals, unopened plastic water bottles can last for several years. However, the taste and quality may begin to change after two years.
- Plastic Bottles: These can potentially leach chemicals into the water over time, especially if exposed to heat or sunlight.
- Glass Bottles: These are more stable and do not leach chemicals, making them a better long-term storage option.
What Affects the Shelf Life of Bottled Water?
Several factors can affect the shelf life of bottled water. Understanding these can help you ensure your water remains safe and pleasant to drink.
- Storage Conditions: Keep bottles in a cool, dark place to prevent heat and light exposure, which can degrade the bottle and water quality.
- Material of the Bottle: Plastic bottles can leach chemicals like BPA into the water over time, especially when exposed to heat.
- Bottle Seal: A broken seal can lead to contamination, making the water unsafe to drink.
How to Tell If Bottled Water Has Gone Bad?
While water itself doesn’t spoil, bottled water can become unsafe or unpleasant to drink if the bottle is compromised.
- Smell and Taste: If water has a strange taste or odor, it’s best not to drink it.
- Bottle Condition: Check for any damage or warping in the bottle, as this could indicate exposure to heat or chemicals.
- Cloudiness: Water should be clear. Cloudy water might indicate contamination.
Is It Safe to Drink Expired Bottled Water?
Bottled water doesn’t expire in the same way food does, but it can become stale or contaminated over time. Drinking water from a bottle that has been stored properly and remains sealed is generally safe, even past its "best by" date. However, always check for any signs of spoilage before consuming.
How to Properly Store Water Bottles?
Proper storage is key to maintaining the quality and safety of bottled water. Here are some tips:
- Keep Away from Sunlight: Store in a dark place to prevent UV light from degrading the bottle and water.
- Maintain a Cool Temperature: Ideally, store bottles at room temperature or cooler.
- Avoid Storing Near Chemicals: Keep bottles away from cleaning supplies or gasoline, which can permeate the plastic.

Can Bottled Water Go Bad in Heat?
Yes, heat can cause the plastic of the bottle to degrade, potentially leaching harmful chemicals into the water. Always store bottled water in a cool place.
How Long Does Water Last in Glass Bottles?
Water in glass bottles can last indefinitely if stored properly, as glass does not leach chemicals. However, it’s still best to consume it within a few years for optimal taste.
Does Bottled Water Need to Be Refrigerated After Opening?
While refrigeration is not necessary, it can help maintain taste and prevent bacterial growth. Consume opened bottled water within a few days.
What Happens If You Drink Expired Bottled Water?
If the water has been stored properly and shows no signs of contamination, it is usually safe to drink. However, if it tastes or smells off, it’s best to discard it.
Why Do Bottled Waters Have Expiration Dates?
Expiration dates are primarily for quality assurance. They indicate the period during which the water is expected to taste its best.
Conclusion
While bottled water can technically last indefinitely, for the best taste and safety, it is wise to consume it within 1-2 years. Proper storage is crucial in preserving its quality. Always check for signs of spoilage before drinking, and remember that glass bottles offer a more stable option for long-term storage.
