Here’s a fact that’ll make you gag: you’re the main contaminant. That seal on the bottle? It’s sterile inside until you crack it open. But the moment your lips touch the rim, you’ve launched a bacterial buffet. Your mouth is home to millions of microbes—harmless ones, mostly—but they love warm, moist environments. Leave that half-drunk bottle in your gym bag for a week, and you’ve created a tiny, damp civilization of bacteria that’s now issuing visas for mold.
That’s why the expiration date on an unopened bottle is mostly for show—it’s the lawyers who care. Companies slap a date on there (usually two years) to cover their behinds from phantom lawsuits about plastic leachates. For an opened bottle? You should drink it within a few days, or it starts tasting like you’re licking a shower drain. Seriously—don’t do that. Your taste buds deserve better.
