Water stored in a bottle can remain safe to drink for up to two years if sealed properly, but once opened, it should be consumed within a few days to ensure freshness and safety. The safety of bottled water depends on factors such as storage conditions and the type of bottle used.
How Long Does Bottled Water Stay Safe?
When it comes to bottled water, understanding its shelf life is crucial for maintaining health and safety. Unopened, commercially bottled water can remain safe to drink for an extended period, often up to two years or more. This longevity is due to the sealed environment that prevents contamination.
Factors Affecting Bottled Water Safety
Several factors can impact how long bottled water remains safe:
- Storage Conditions: Keep bottled water in a cool, dark place to prevent degradation. Avoid exposure to direct sunlight or heat, which can cause plastic bottles to leach chemicals.
- Type of Bottle: Glass bottles are generally more stable than plastic, which can degrade over time, especially under heat.
- Seal Integrity: Ensure the seal is intact before storing. Once opened, the water should be consumed within a few days.
How to Store Bottled Water Safely?
Proper storage is key to maintaining the quality and safety of bottled water:
- Temperature: Store at room temperature or cooler, ideally between 50°F and 70°F.
- Location: Avoid garages or attics where temperatures can fluctuate dramatically.
- Position: Keep bottles upright to prevent leaks and maintain seal integrity.
How Does Bottle Material Affect Water Safety?
The material of the bottle plays a significant role in the safety of stored water. Here’s a comparison of common materials:
| Feature | Plastic Bottles | Glass Bottles | Stainless Steel Bottles |
|---|---|---|---|
| Durability | Moderate | High | High |
| Chemical Leaching | Possible | None | None |
| Weight | Light | Heavy | Moderate |
| Reusability | Limited | High | High |
What Happens If Bottled Water Expires?
While bottled water itself does not expire, the packaging can degrade over time. An expired bottle may:
- Develop an off-taste due to plastic leaching.
- Become prone to leaks if the bottle integrity is compromised.
- Lose its quality if exposed to light and heat.
Is It Safe to Drink Bottled Water Past Its Expiry Date?
In most cases, bottled water is still safe to drink past its expiry date if stored correctly. However, if the bottle shows signs of degradation or if the water has an unusual taste or odor, it is best to discard it.

How Can You Tell If Bottled Water Has Gone Bad?
Bottled water may have gone bad if it has an unusual taste, odor, or if the bottle is damaged. Check for any discoloration or floating particles, which indicate contamination.
Can You Reuse Plastic Water Bottles?
While you can reuse plastic bottles, it’s not recommended due to potential chemical leaching and bacterial growth. If you choose to reuse, clean thoroughly with hot, soapy water.
What Are the Best Alternatives to Plastic Bottles?
Consider using glass or stainless steel bottles as alternatives. They are more durable, environmentally friendly, and do not leach chemicals into the water.
Does Bottled Water Go Bad in Heat?
Yes, heat can cause plastic bottles to degrade, leading to chemical leaching. Always store bottled water in a cool environment to prevent this.
How Long Can You Keep Bottled Water in a Car?
Avoid keeping bottled water in a car for extended periods, especially in hot weather. The heat can accelerate plastic degradation and potentially contaminate the water.
Conclusion
Understanding the factors that affect the safety of bottled water is essential for ensuring that it remains a reliable source of hydration. Proper storage and awareness of the material and conditions can extend the shelf life and maintain the quality of bottled water.
