It might seem counterintuitive, but it isn't easy to find all-natural, almost totally pure water. Anything that comes into contact with land inevitably picks up some minerals — and thus flavors — along the way, which makes Berg Iceberg Bottled Water an outlier. It's made by melting massive iceberg chunks that have broken off from 15,000-year-old glaciers, resulting in truly virginal water with a TDS (total dissolved solids) of 10 ppm, one of the lowest available. The chunks are harvested by hand off the shores of Newfoundland, Canada, and are melted and bottled under strict quality conditions in order to preserve the water's natural qualities. Available in handsome 750ml glass bottles.
