What an interesting topic!

My favorite bottled water -- which I can't seem to find here in Texas - is a sparking water, in a dark blue bottle. I believe it comes from the UK (I had it daily while living/working in London).

Great clean taste - with a palatte of tingly bubbles. Was a great substitute for soda's (trying to lose a few pounds after nibbling all those finger foods during afternoon tea).

I wanna say it started with a T - like Tyros, or Tyrant - but my mind draws a blank.

ANother favorite water -- both still and sparkling -- is VOSS -- comes in a cool cylinder shapped bottle and hits the spot nicely. First discovered it at a Fondue restauarnt in Tallahasse, FL (the Melting Pot, if I recall was the name).
