Bottled water can last indefinitely if stored properly, but it’s best consumed within two years for optimal taste and quality. The shelf life depends on storage conditions, packaging materials, and whether the bottle has been opened.
How Long Does Bottled Water Last Unopened?
Unopened bottled water can last for many years. While the shelf life of bottled water is technically indefinite, manufacturers often recommend consuming it within two years. This recommendation is based on maintaining the best taste and quality, as well as ensuring the integrity of the bottle.
- Plastic bottles: These are typically safe for two years. Over time, plastic may leach chemicals into the water, especially if exposed to heat.
- Glass bottles: These can last indefinitely without affecting the water’s taste or safety, provided they remain sealed.
What Factors Affect the Shelf Life of Bottled Water?
Several factors can impact how long bottled water stays fresh and safe to drink:
- Storage conditions: Keep bottled water in a cool, dark place away from direct sunlight and heat sources to prevent chemical leaching from plastic containers.
- Packaging material: Glass bottles are more stable over time compared to plastic, which can degrade and affect water quality.
- Sealing and opening: Once opened, bottled water should be consumed within a few days to a week. Open bottles are prone to contamination and taste changes.
How to Store Bottled Water for Maximum Shelf Life
Proper storage is crucial for maintaining the quality of bottled water. Follow these tips to ensure your water stays safe and fresh:
- Store in a cool, dark place: Avoid areas with direct sunlight or temperature fluctuations.
- Keep bottles sealed until use: This prevents contamination and preserves freshness.
- Use glass bottles for long-term storage: They are less likely to degrade over time.
Can Bottled Water Go Bad?
While bottled water doesn’t spoil like perishable food, it can develop an off taste or odor if not stored correctly. Factors such as exposure to sunlight, heat, and chemicals from plastic bottles can impact the water’s quality.
- Taste and odor changes: These are often due to the breakdown of plastic or contamination.
- Cloudiness or particles: This may indicate contamination or degradation of the bottle material.

How Can You Tell if Bottled Water Has Gone Bad?
Check for off smells, tastes, or visible particles. If the water looks cloudy or has an unusual taste, it may be best to dispose of it.
Summary
While bottled water can last indefinitely if stored properly, it’s best consumed within two years for optimal taste and quality. Proper storage conditions, such as keeping bottles in a cool, dark place, can extend the shelf life and maintain the water’s safety.
