Suntory Ice Bar‏

Suntory is selling two forms of branded ice cubes. One uses a process developed by Nichirei to which retains all the minerals in spring water while not adding any extra air, resulting in white cubes. The other uses a combination of ion exchange and reverse osmosis filtration to obtain water 1,000 times as pure as tap water, and thus extra clear cubes. These are being promoted for use with Suntory spirits and beverages.
