Think of that forgotten water bottle like a houseguest who overstays their welcome. It’s not that they turn evil; they just start picking up the weird habits of the place they’re in. If you leave a bottle in a hot car, it starts to taste like… well, hot car. It’s a flavor you can’t un-taste.
The plastic itself can also start to leach chemicals into the water, especially if it’s been baked in the sun for weeks. It’s not poison, but it’s not exactly crisp mountain spring anymore. It’s more like “vague chemical hint” with a side of regret.
I once found a bottle of water under my couch cushion that had been there since New Year’s Eve. It was from three Christmases ago. I stared at it like it was a relic from a lost civilization. Did I drink it? Absolutely not. But I also didn’t throw it away for another month because I was too embarrassed by my own laziness.
Expiration dates are more about the bottle than the water
Here’s the kicker: those “best by” dates on water bottles? They’re mostly for the plastic, not the water itself. The FDA doesn’t require them for water, but companies slap them on anyway to sound responsible. After a year or two, the plastic can begin to degrade, making the water taste like a plastic bag that’s been left in a sauna.
And then there’s the whole “stagnant water” problem. If you open a bottle and leave it for a few days, it starts to taste flat. It’s like the water got bored and forgot how to be refreshing. You know that sad, lukewarm sip from a cup you left on your nightstand? That’s the vibe.

So, while the water won’t “go bad” in a deadly sense, it will definitely go “meh”. And nobody wants to pay two bucks for a bottle of meh.
