Times are for unopened, properly stored mineral water and reflect best quality. Always use your senses and follow any date on the package.
Signs mineral water has gone bad
- Off, sour, or fermented smell.
- Cloudiness, sediment, or fizzing in something that shouldn't be carbonated.
- A bulging or swollen container.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store mineral water
Keep sealed shelf-stable drinks in a cool, dark place. Refrigerate after opening and use within a few days. Dry beverages like tea and coffee keep best in airtight containers away from light and moisture.
