Want to Know if Bottled Water Expires?

Ever dug out an old water bottle and wondered, “Can I still drink this?” You’re not alone – so let’s get real about whether bottled water expires, how long it lasts, and why storage matters.

Does Bottled Water Expire?

Nope, not exactly. The water itself won’t turn into swamp juice, but the bottle material can degrade over time—especially plastic.

How Long Does Bottled Water Last?

Unopened bottled water typically stays fresh for 1–2 years (plastic) or 2–3 years (glass). But once opened? Drink within 2–3 days before bacterial growth starts.

Does Bottled Water Expire in Heat?

Absolutely! Leaving bottles in the sun or a hot car speeds up bottle degradation, which can affect taste and safety.
