I wonder if anyone has worked out the full environmental impact of doing this instead of drinking tap water. Apart from the energy costs in producing + disposing of all the bottles, there's transporting the stuff half way across Europe...
That said, I think the 2-year old one that's on my desk at the moment could do with replacing. It's got algae growing around the top half and some kind of greyish scum growing on the bottom, which occasionally flakes off and floats about in a rather offputting manner. Doesn't seem to affect the flavour though.
