Fine water is a growing category worldwide, even in water-stressed countries like India, where one company imports natural spring water that's bottled in sleek glass bottles in Bhutan.

Millions of people worldwide don’t have clean water to drink, even though the United Nations deemed water a basic human right more than a decade ago. Yet, even as extreme heat dries up more aquifers and wells and leaves more people thirsty, luxury water has become fashionable among the world’s privileged, who uncap and taste it like fine wine.

Fine water is drawn from volcanic rock in Hawaii, from icebergs that have fallen from melting glaciers in Norway, or from droplets of morning mist in Tasmania. The rarest of all, often bottled in collectable glass, sell for hundreds of dollars apiece.

Associated Press teams reported on the trend from India, Bhutan and Greece.
