Can bottled water go expired? The short answer is no, bottled water itself does not expire. However, the quality and taste of bottled water can change over time due to factors like storage conditions and the type of plastic used in the bottle. Understanding these factors can help ensure that your bottled water remains safe and pleasant to drink.
Why Doesn’t Bottled Water Expire?
Bottled water is a shelf-stable product, meaning it doesn’t spoil or become unsafe to drink under typical conditions. The FDA (Food and Drug Administration) does not require a shelf life for bottled water, as water is an inherently stable compound that doesn’t support microbial growth. However, plastic bottles can affect the water’s taste and quality over time.
How Does Packaging Affect Bottled Water?
What Role Does Plastic Play?
Plastic bottles, especially those made from PET (polyethylene terephthalate), can slowly degrade, affecting the water’s taste and quality. Over time, chemicals from the plastic can leach into the water, altering its flavor. This process is accelerated by exposure to heat and sunlight, so it’s essential to store bottled water in a cool, dark place.
How Does Storage Impact Water Quality?
- Temperature: High temperatures can increase the rate at which plastic degrades. Always store bottled water in a cool environment.
- Sunlight: Direct sunlight can promote algae growth in clear bottles and increase plastic degradation.
- Odors: Plastic bottles can absorb odors from their surroundings, so keep them away from strong-smelling substances.
What Are the Best Storage Practices?
To maintain the quality of your bottled water, follow these storage tips:
- Keep bottles in a cool, dark place.
- Avoid storing near chemicals or cleaning products.
- Rotate your stock to use the oldest bottles first.
Do Bottled Water Brands Differ in Quality?
Different brands use different types of plastic and bottling processes, which can affect the water’s shelf life and quality. Here’s a comparison of some popular bottled water brands:
| Brand | Plastic Type | Shelf Life (Recommended) | Unique Feature |
|---|---|---|---|
| Brand A | PET | 2 years | Eco-friendly bottles |
| Brand B | HDPE | 3 years | Enhanced minerals |
| Brand C | Glass | Indefinite | Pure spring source |

How Long Can Bottled Water Be Stored?
Bottled water can be stored indefinitely if kept in optimal conditions. However, for the best taste and quality, it’s recommended to consume it within two years of the bottling date.
Can Bottled Water Make You Sick?
While bottled water itself doesn’t spoil, improper storage can lead to contamination. Always check for signs of damage or leakage in the bottle, and avoid drinking water with an off taste or smell.
Is It Safe to Drink Bottled Water Left in a Hot Car?
It’s generally not recommended to drink bottled water left in a hot car, as high temperatures can accelerate the leaching of chemicals from the plastic into the water. If possible, store water in a temperature-controlled environment.
Does Bottled Water Taste Different Over Time?
Yes, bottled water can develop an off taste over time due to leaching from the plastic or absorption of odors. Proper storage can minimize these changes.
Why Do Some Bottles Have an Expiration Date?
Some manufacturers include an expiration date for inventory management and to ensure consumers enjoy the best taste and quality. It’s more about maintaining the bottle’s integrity than the water itself.
Conclusion
While bottled water doesn’t expire in the traditional sense, its quality can diminish over time due to factors like plastic degradation and storage conditions. By understanding these factors and following proper storage guidelines, you can ensure that your bottled water remains safe and enjoyable to drink.
