Water cannot expire, but it can get contaminated.
If it's properly closed so it can't evaporate or if bacterias and other micro-organisms or chemicals can't get in the bottle - then it's safe.
Basically if it's sealed tightly enough so that molecules or unicellular organisms can't get in, or hydrogen (H) and oxygen (O) molecules out and it's kept in a dark place or in a UV light resistant bottle, the quality of water cannot change.



Water can expire...but it would actually take a very long time to become undrinkable. If the bottle is unopened and the water pure it can stay drinkable for many years. The makers of bottled water have to add an expiry date by law, but in reality it's not really needed.

I believe that if you were to freeze your drinking bottled water it would keep indefinately. How ever I see mixed answers here as to yes it has a expiration date on the container it is bottled in or no it does not have a expiration date. Fact is it must depend on the bottler. I have (myself) seen expiration dates on bottled water but it was good for at least 2 yrs. Side note: If you ever decide to freeze a liquid make sure that there is room for expansion of the freezing product. I freeze bottled 1 gal. drinking water by draining off about 1/5 to 1/4 of the water from full bottle. Bottle will split if not properly drained. I save a empty bottle and pour off about 5 full gal bottles to the freeze acceptable level of each individual bottle.



its the packaging of the water that can get you in trouble.. if water is left open it can get stagnant and bacteria and bugs can grow in it..
natural water in life is moving constantly where as its airated and gets clean naturally..

if water was stored in a closed sealed glass or pottery container (not plastic which will biodegrade) then it would keep for millions of years..

ice glaziers in our polar regions are natural water stores..

all the water we have on earth regenerates itself, its always been here and always will be here.. its just recycled.. the world doesnt make "new" water, it just recycles whats already here..

just think (as my 8yr seems to tell me) that if you drink recycled water, you probably are drinking dinasaur pee.. hahahahaha!... true though..



I suppose it would be fine. As long as you do not open it. Water does not have an expiration date. If you were to open it you would have to keep it cool some how. I am not sure why you would want to do that but okay...

Water has no expiration date



In theory it might expire. Keeping it away from the elements might delay this.

Water though has nothing to do with the alcohol section you posted this in.
Acccording to yahoo answers = it is a violation to post in the wong section!



water is as old as the earth. it cannot expire or rot as it does not contain any carbon. if it is in a plastic bottle it might taste a little funky though.



there would probably be bottle degradation from the plastic... So no, don't wait 2 years to drink it... It wouldn't be the water that would start going bad first, it would be the bottle.



It's fine all it is are bonded hydrogen and oxygen molecules and some minerals.
