Should I be worried about my aluminium drinks bottle?

i wouldn't drink from a bare aluminium bottle - i'm pretty sure they don't recommend anything acidic in them as it will dissolve the aluminium pretty easily. (aluminium causes alzheimers). get a coated one or a steel bottle.

I've heard this too, and many drinks are acidic. Stainless steel would be fine.

Yet fizzy drinks are kept in Aluminium Cans and are quite acidic...........hmmmm

pH levels from here http://news.softpedia.com/images/news2/Cola-Destroys-Your-Teeth-3.jpg not sure on how accuracy

Do you have a picture of the bottle, as surely its simply something to do with the little drinks dispenser venting the vacuum from your sealed bottled once you have drunk some of the liquid?

This.

I bought a standard plastic bottle of Ribena, left it over the weekend and on Monday morning it tasted fermented. Also there was hiss as I opened it.

It doesn't do it if I use a disposable mineral water bottle, even after a few days.

It's one of these:

It's definitely nothing to do with the temperature change, because I release the pressure every time I open it for a sip. Quite a lot of pressure builds up in it, there's definitely a reaction going on.

all aluminium cans are coated on the inside by a thin layer of polymer - otherwise they would dissolve.

Wiki said:
Many consumers find the taste of a drink from a can to be different from fountain drinks and those from plastic or glass bottles.[citation needed] In addition, some people believe that aluminum leaching into the fluid contained inside can be dangerous to the drinker's health.[8] Scientific consensus is that aluminum plays no role in the development of Alzheimer's disease.[9][10] Aluminum cans often contain an internal coating to protect the aluminum from beverage corrosion, but still, trace amounts of aluminum can be degraded into the liquid, which amounts vary depending on factors such as storage temperature and liquid composition.[11][12] Chemical compounds used in the internal coating of the can include types of epoxy resin.[13]

As I said not always and its done to stop it over a long period of time, the drinks wouldn't just disolve the cans over night.

I bought a Sigg one in the end. It's much better and I should have just bought it in the first place. Cheapskate :D

The Sigg one is coated on the inside to stop it reacting. It's quite a lot stronger as well. I can't dent it with my thumb. Well, I could if I really wanted, but not as easily :D
