How Long Is Bottled Water Good For?

If stored properly in a cool, dark place away from heat and sunlight, unopened bottled water can remain safe and drinkable for well beyond two years, even up to five years, though the taste may change. Glass bottles offer longer stability since they don't leach chemicals like plastic.

Once opened, bottled water should be consumed within a few days (about 4 to 6 days refrigerated) as exposure to air and contaminants reduces safety and freshness. Temperature fluctuations and poor storage can accelerate bottle degradation and water quality changes.
