Drinking month-old bottled water is generally safe if the bottle remains sealed and stored properly. However, once opened, it’s best to consume bottled water within a few days to ensure freshness and avoid potential contamination.
Is It Safe to Drink Month-Old Bottled Water?
Understanding Bottled Water Expiration
Bottled water doesn’t spoil like perishable food items, but it does have a "best by" date. This date indicates when the water will be at its freshest and best-tasting. Unopened bottled water stored in a cool, dark place can remain safe to drink for months or even years past this date. However, the taste might begin to change over time.
What Happens When Bottled Water Is Opened?
Once a bottle is opened, its safety can be compromised. Exposure to air and potential contaminants can lead to bacterial growth. To maintain safety:
- Consume opened bottled water within a few days.
- Refrigerate if possible to slow down bacterial growth.
- Avoid direct sunlight as it can degrade the plastic and affect the water.
How Does Storage Affect Bottled Water Safety?
Proper storage is crucial for maintaining the safety and quality of bottled water. Here are some tips:
- Keep bottles in a cool, dark place to prevent plastic degradation.
- Avoid storing near chemicals or cleaning products, as plastic can absorb odors.
- Check for damage to the seal or bottle, which can allow contaminants to enter.
Does Plastic Leach into Bottled Water?
There is ongoing debate about whether chemicals from plastic bottles can leach into water over time. Factors that can increase leaching include:
- High temperatures can cause plastic to break down, potentially releasing chemicals.
- Extended storage times might increase the risk of leaching.
While most bottled water is safe, using alternatives like stainless steel or glass bottles can alleviate concerns about plastic leaching.

What Are the Risks of Drinking Old Bottled Water?
Drinking old bottled water, especially if opened, can pose risks such as exposure to bacteria or chemicals from degraded plastic. Always check the bottle for any strange odors or tastes before consuming.
Can Bottled Water Go Bad in Heat?
Yes, heat can cause the plastic to break down, potentially releasing harmful chemicals into the water. It’s best to store bottled water in a cool, shaded area to prevent this.
How Long Does Bottled Water Last Once Opened?
Once opened, bottled water should ideally be consumed within 3-5 days. If refrigerated, it may last a bit longer, but it’s essential to check for any off flavors or odors.
Is It Safe to Drink Bottled Water Past the Expiration Date?
Generally, yes, as long as the bottle is unopened and stored properly. The expiration date is more about quality than safety, but always inspect the bottle for damage or unusual smells.
What Are the Benefits of Using Reusable Water Bottles?
Reusable water bottles reduce plastic waste and can be safer for long-term use. Materials like stainless steel and glass don’t leach chemicals and can keep water fresh and taste-free.
Conclusion
In summary, drinking month-old bottled water is typically safe if the bottle is unopened and stored properly. Once opened, consume the water quickly and store it in a refrigerator to ensure safety. Consider using reusable bottles to reduce environmental impact and eliminate concerns about plastic leaching.
