Coming soon to a restaurant near you: a polar bear's home in a glass. Bottled water taken straight from an iceberg in Greenland is about to be made commercially available at around £6 a bottle.

"It is so tasteless that it actually creates a taste," according to Ron Stamp, the man behind Glace Rare Iceberg Water. "The tastelessness is its own taste. It's like drinking air."

Mr Stamp has been fascinated with icebergs for 20 years, but attempts to sell iceberg vodka and beer have failed. He is about to set sail in a converted fishing boat from his native Canada, bound for a fjord in Greenland. His vessel will rip off 700kg chunks of ice and store them below deck.
