Here’s your takeaway: bottled water doesn’t “expire” like milk. It just degrades gracefully—like a celebrity who refuses to get a facelift. It’s safe to drink from a sealed bottle that’s a year or two old, as long as it’s been stored out of the sun and away from your car’s hotbox of doom.
But if you’re aiming for peak taste, treat plastic bottles like leftovers: consume within a year, and never from the forgotten corner of the garage. And if you really want to be fancy, switch to a reusable metal or glass bottle. Your taste buds will applaud, and the planet will send you a thank-you note written on recycled paper.
In short: water lasts forever, but plastic is a bad roommate. Keep it cool, keep it dark, and for the love of hydration, don’t drink from a bottle that looks like it survived a zombie apocalypse. Your future self—and your dignity—will thank you.
