supermarket water

Post by kernewek » Wed Nov 18, 2015 8:32 pm

Might be a dumb question, but I've seen a few comments about what containers to store water in at home. Is there actually anything wrong with normal bottled water for long term storage? The own brand stuff at the supermarket these days seems to be cheap as chips.

That's what I do I rotate stocks through summer by slapping them in the fridge for a cool drink and replace

Nothing wrong at all.

There is a theoretical risk that chemicals from the plastic can leech into the water when stored for long times. But that hasn't been proven. The best-before dates are more about known durations of guaranteed quality rather than any concern over fitness for purpose or safety.

10 years after TSHTF and I find a bottle of evian in a bombed out house, I think I'd happily drink it...

Its still water (geddit) and there's nothing wrong with tap water, I get that if you want princess spring water then you'll feel cheated but when it costs the same as the own brand cheapy lemonade you know its not going to be Highland Spring. My biggest concern is that its in transparent bottles, I keep most of my water in dark containers, I do have some transparent bottles though, its easy to buy and store.

Even though it's tap water I wonder if the supermarket stuff is likely to be bottled under more sterile conditions than someone filling bottles at home?

Plastic does degrade over time, so make sure you rotate stocks and keep them out of direct sunlight, which can speed the process.

As for sterility, bottling your own tap water is as sterile as you want to make it. Doing distilled water isn't hard, although you may find it a bit of a faff. If you're using glass, you can sterilise using the oven or even something like Milton. Entirely up to you :)

As i've heard it for many a year, the expiration date on bottled water is for the bottle, not the water.

It's really a matter of the BPA (Bisphenol A) content of the polymer use in the bottles production, although this concern has been pubic knowledge for some time now and the vast majority of suppliers state such information on the packaging (not sure if that's now a legal requirement?)

here's what wiki have to say about it..
https://en.wikipedia.org/wiki/Bisphenol_A#Use

but generally kept out of sunlight and rotated in a timely fashion shouldn't be an issue.
