Drinking bottled water after two years can be safe, but it depends on storage conditions and the type of bottle. While bottled water doesn’t spoil like perishable food, its quality can degrade over time. Understanding the factors affecting bottled water’s shelf life will help you make informed decisions.
How Long Does Bottled Water Last?
Understanding Expiration Dates on Bottled Water
Bottled water typically comes with a "best by" date rather than an expiration date. This date, usually set at two years from the bottling date, indicates when the water is expected to maintain optimal taste and quality. However, bottled water doesn’t "expire" in the traditional sense.
Factors Affecting Bottled Water Quality
Several factors influence the quality of bottled water over time:
- Storage Conditions: Keep bottled water in a cool, dark place away from direct sunlight and chemicals. Heat and light can cause the plastic to leach chemicals into the water.
- Type of Plastic: PET (polyethylene terephthalate) bottles are more prone to leaching chemicals than glass or BPA-free options.
- Seal Integrity: Ensure the seal is intact. A broken seal can introduce contaminants.
Is It Safe to Drink Bottled Water After Two Years?
Generally, bottled water remains safe to drink past its "best by" date if stored properly. However, taste and odor might be affected. If the water smells or tastes off, it’s best to discard it.
Comparing Bottled Water Storage Options
| Feature | PET Bottles | Glass Bottles | BPA-Free Bottles |
|---|---|---|---|
| Price | Low | High | Medium |
| Durability | Moderate | High | High |
| Leaching | Possible | None | Minimal |
Practical Tips for Storing Bottled Water
- Avoid Sunlight: Store in a shaded area to prevent chemical leaching.
- Temperature Control: Keep in a cool environment to preserve taste.
- Check Seals: Regularly inspect for cracks or leaks.

How Can You Tell if Bottled Water Has Gone Bad?
While water itself doesn’t spoil, if bottled water develops an unusual smell, taste, or appearance, it’s best to avoid drinking it. These changes can indicate contamination or chemical leaching.
What Happens if You Drink Expired Bottled Water?
Drinking bottled water past its "best by" date is generally safe if the bottle was stored properly. However, the taste might be affected, and in rare cases, chemical leaching could pose health risks.
Can Bottled Water Grow Mold?
Mold can develop in bottled water if the seal is broken or if the water is exposed to contaminants. Always check the seal before drinking.
Is It Better to Store Water in Glass or Plastic?
Glass bottles are preferred for long-term storage as they don’t leach chemicals. However, plastic bottles are lighter and more convenient for short-term use.
How Long Can You Store Water for Emergency Preparedness?
For emergency preparedness, it’s recommended to store water for no more than six months to ensure freshness. Rotate your supply regularly and consider using glass bottles for longer storage periods.
Summary
In conclusion, while bottled water doesn’t technically expire, its quality can degrade over time, especially if not stored properly. By understanding storage conditions and the type of bottle used, you can ensure that your bottled water remains safe and pleasant to drink.

Call to Action: Always inspect your bottled water before consumption, and consider upgrading to glass or BPA-free bottles for better long-term storage.
