Drinking water doesn’t have a specific expiration date like perishable food items, but its quality can degrade over time due to storage conditions. Properly stored, sealed bottled water can last indefinitely, but it’s recommended to consume it within two years for optimal taste and safety.
How Long Does Bottled Water Last?
Bottled water is generally considered to be safe for an extended period if stored correctly. While water itself doesn’t spoil, the plastic bottles can leach chemicals over time, potentially affecting the taste and safety.
- Unopened bottled water: It can last indefinitely if stored in a cool, dark place away from chemicals and sunlight. However, for best taste and quality, it’s advisable to consume it within two years.
- Opened bottled water: Should be consumed within a few days to a week and kept refrigerated to maintain freshness.
Factors Affecting Bottled Water Quality
Storage Conditions
Proper storage is crucial for maintaining the quality of bottled water. Here are some tips for optimal storage:
- Temperature: Store in a cool environment, ideally below 70°F (21°C).
- Light: Keep away from direct sunlight to prevent chemical leaching from the plastic.
- Chemicals: Avoid storing near chemicals, as they can permeate the plastic and contaminate the water.
Bottle Material
The type of plastic used in water bottles can impact the water’s longevity and safety.
- PET plastic: Commonly used for single-use bottles, it can leach chemicals like antimony and phthalates over time.
- HDPE plastic: Used for larger water containers, it is more stable and less likely to leach chemicals.
Is It Safe to Drink Expired Water?
While water itself doesn’t expire, the container can affect its safety and taste. Drinking water from bottles that have been stored for a long time is generally safe if the seal is intact and the water has been stored properly. However, if the water has a strange odor or taste, it’s best to discard it.
How to Tell If Bottled Water Has Gone Bad
Here are some signs that bottled water might not be safe to drink:
- Unusual smell: A chemical or plastic odor can indicate leaching from the bottle.
- Off taste: A stale or plastic-like taste may suggest degradation.
- Cloudiness: Clear water should be free from particles or cloudiness.

Does Tap Water Expire?
Tap water doesn’t expire, but its quality can decline over time. It’s best to consume it within a day or two if stored in a clean container in the refrigerator.
How Can I Store Water Long-Term?
For long-term storage, use food-grade containers made of glass or stainless steel. Ensure they are airtight and stored in a cool, dark place.
Can Water Get Contaminated in Plastic Bottles?
Yes, water can become contaminated if plastic bottles are exposed to heat or sunlight, leading to chemical leaching. Always store bottles properly to minimize risk.
Should I Rotate My Emergency Water Supply?
Yes, it’s a good practice to rotate your emergency water supply every six months to ensure freshness and safety.
Is Distilled Water Better for Long-Term Storage?
Distilled water is free from impurities and minerals, making it a good option for long-term storage. However, it should still be stored in appropriate containers to prevent contamination.
Conclusion
While drinking water doesn’t have a traditional expiration date, its quality can be compromised by improper storage. To ensure safety and taste, store water in a cool, dark place and check for signs of contamination before consumption.
