If you keep your bottled water cool, dark, and out of the sun (like a vampire with a hydration habit), it’s safe to drink for years. The FDA doesn’t even require expiration dates for bottled water—they’re mostly a suggestion, not a rule. I’ve personally sipped a bottle that was three years old, and guess what? I’m still here to write this article.
But let’s be honest: taste is the real judge. After about 6–12 months, the water might start tasting “flat” or plasticky. It’s not dangerous, just disappointing—like finding out your favorite chips are stale. So if you’re planning to stockpile for a zombie apocalypse, rotate your stash like you’re a water sommelier.
