The best before date is based on a number of factors. The two most important are the rate at which the plastic container the water in leeches chemicals into the water, and the mineral content of the water and what effects light and heat may have on the water. Usually the best-before date is still at least one year after the water has been bottled.
To keep water for longer periods of time, buy purified water rather than spring water, because it does not contain the disolved minerals, and store bottled water in a cool place away from sunlight (this slows the process which allows chemicals from the plastic to leech into the water).
If the water has a "plastic" taste, don't drink it. Otherwise, it is still fine even if the expiration date has passed.

Still water only goes stale if it comes into 'contact' with air - that is - molecules of whatever is being carried in the air lands on the surface of the water and then reacts with it - also using the surrounding air as part of the reaction.
Sealed water in bottles or containers does not have this problem - but - as many have said - the actual container - starts to react with the water - but actually the water gets 'tainted' by the plastic or the container.
The same actually happens with tins - food finally starts to react with its container and spoils.
If you want proof - get yourself a bottle of still spring water and put it into your wardrobe and forget it until next year and then check it - you may find it palatable or just tasting of plastic - but definately with no algae in it.

The 'best before' date is not for the water inside bur for the plastic bottle itself, as after a long time plastic particles starts to fall from the bottle's inside and get mixed with the water.

The date is based on when the plastic from the bottle starts to leech into the water

It must go off i guess. I remember years ago finding a plastic bottle in the boot of my car that i'd filled with tap water ages ago, and there was a big scary looking thing growing in it - looked like the branch of a tree. Was disgusting.

Seems silly doesn't it but think about it leave water on a plastic bottle for years and it will go stagnant

Becuase the plastic of the bottle can make it taste a bit funny after a lot of time.

Probably because there are also some "friendly bacteria" in it....:-))) The mineral water is not distilled water after all.

beats the hell outta me - they boast it takes half a million years to filter down through a glacier or some such and then warns you to drink it within a month. Strange world, innit?
