For unopened, store-bought plastic bottles, most experts say they’re at their best for about 1 to 2 years after the production date. After that? The taste declines, but you won’t get sick.
Once you open the bottle, though, the clock ticks faster. You’ve just introduced air and mouth bacteria. Drink it within a few days if you can—like a cup of coffee you left out overnight.

And glass bottles? They’re the heroes of the story. Glass doesn’t leach anything, so water in glass can last almost indefinitely if stored properly. It’s like a time capsule for your hydration.
What About That Bottle You Found in the Attic?
Let’s be real: if your bottle is dusty, warped, or smells weird, don’t risk it. Your instincts are smarter than a date stamp. It’s like finding a mystery can of soda from 2015—possible, but why bother?
Also, heat is the enemy. A bottle left in a hot car for weeks will degrade faster. The plastic can release bisphenol A (BPA) and other compounds. Not ideal for your vibe.
So, the cool part? Water is basically immortal. But the container and environment are what decide if it’s still tasty and safe.
