You can drink expired sparkling water, but its taste and carbonation may diminish; check for off smells or changes before consuming.
Many people wonder if they can drink sparkling water past its expiration date. The short answer is yes – but with some important caveats. While expired sparkling water won’t make you sick, its quality and taste may degrade over time.
Does Sparkling Water Actually Expire?
Sparkling water doesn’t truly “expire” in the way perishable foods do. The expiration date on bottles is more about quality than safety. Properly stored unopened sparkling water can last 1-2 years past its printed date.
Unlike regular water, sparkling water contains dissolved carbon dioxide gas that creates its signature bubbles. This carbonation acts as a natural preservative, inhibiting bacterial growth. However, the fizz does dissipate over time.
Factors That Affect Sparkling Water Shelf Life
- Packaging: Glass bottles retain carbonation better than plastic
- Storage temperature: Heat accelerates CO2 loss
- Light exposure: UV rays degrade plastic and affect taste
- Seal integrity: Damaged caps allow gas to escape
How to Tell If Sparkling Water Has Gone Bad
While expired sparkling water is generally safe, watch for these signs it’s past its prime:
| Sign | What It Means |
|---|---|
| Flat taste | Lost carbonation – safe but less enjoyable |
| Off odors | Possible contamination – discard |
| Cloudy appearance | Mineral precipitation – harmless but unappealing |
| Plastic taste | Chemical leaching – better to avoid |
Flavored vs. Unflavored Sparkling Water
Flavored varieties like dragon fruit or lemon may degrade faster than plain sparkling water. Artificial flavors and sweeteners can break down over time, creating odd tastes. Always check flavored options carefully before drinking expired products.
Best Practices for Storing Sparkling Water
To maximize shelf life and maintain quality:
- Store unopened bottles in a cool, dark place
- Keep away from heat sources and direct sunlight
- Refrigerate after opening – lasts 3-5 days with tight seal
- Consider using a stainless steel bottle for opened sparkling water
- Check for leaks or damaged packaging before purchasing
Plastic vs. Glass Bottles
Glass containers maintain carbonation and flavor better long-term. Plastic is more prone to absorbing odors and allowing CO2 to escape. According to StillTasty, glass-bottled sparkling water often lasts several months longer than plastic.
Health Considerations
Drinking properly stored expired sparkling water poses no significant health risks. However, some people may experience:
- Mild stomach discomfort from flat carbonated water
- Reduced hydration if avoiding drinking due to bad taste
- Potential exposure to plastic chemicals in very old bottles
For those concerned about plastic exposure, consider transferring sparkling water to glass containers or choosing brands that use BPA-free packaging.
When to Definitely Discard Sparkling Water
Throw away sparkling water if you notice:
- Visible mold or floating particles
- Strong chemical or rotten odors
- Bulging or leaking containers
- Extreme loss of carbonation combined with off-taste
Remember that while sparkling water lasts longer than many beverages, it’s not immortal. When in doubt, follow the old adage: “When it’s questionable, it’s disposable.” For more on beverage storage, check our guide on how long milk tea lasts.
