How long does Bottled Water Last?

Bottled water that is free from contaminants when it is stored does not have an expiration date. This is reinforced by the U.S. Food and Drug Administration (FDA) who do not require expiration dates on bottled water in the US. However, many sources recommend a two year shelf life for most bottled waters.

Keep in mind this recommendation is for water that was either filtered or purified before storage and thus was contaminant free when packaged. Most often this is encountered as bottled water you purchased from the store.

While it does remain safe to drink for an indefinite amount of time, extended storage times will likely cause some taste issues. The water is likely to take on a stale or plastic like taste after an extended time. Despite this taste as long as the water does not have a strange odor it should remain safe to drink.
