If you look closely at a bottle of water, you may notice a few things: Claims that the water came from a natural subterranean source
where it has remained undisturbed for hundreds or thousands of years, and an expiry date indicating that it will be deactivated in January
What is going on here? Is there something in the bottling process, or are bottled water businesses merely pumping water from underground sources in the few months before it spoils?
DOES WATER EVER EXPIRE?
No The water will never expire. Expiration dates are printed on bottles at the same time as other information such as the date of bottling, etc. gets printed
IS IT POSSIBLE FOR BOTTLED WATER TO GO BAD?
Bottled water will not spoil after its expiration date, unlike other foods and beverages.
It does not have proteins and sugars, which are broken down by microorganisms and cause it to become "off."
However, if kept for an extended period of time, the chemicals from the bottle may begin to taste off.
"Bottled water has an unlimited safety shelf life if it is made in accordance with quality standard requirements and maintained in an unopened, properly sealed container," according to the FDA.
So, the FDA doesn't require bottled water to have an expiry date. However. Long-term storage of bottled water may result in aesthetic flaws. Bottlers may choose to include expiration dates on their labels."
