PRESENTED in an unusually-shaped heavy glass bottle with outsized black lettering, it could be a fine vodka. On sale for £80 ($99) in Harrods, an upmarket department store in London, it has a price tag to match. In fact, it is a bottle of water. Harvested directly from Norwegian icebergs that are up to 4,000 years old, Svalbardi is one of hundreds of water brands that are sourced from exotic places and marketed as luxury products. From the basic to the expensive, the market for bottled water is an attractive place to be.
