seltzer water, mineral water containing free carbon dioxide, obtained originally from springs at Niederselters, Germany. Reputed to have curative value in treating several diseases, it became very popular in the 19th cent. In the 20th cent. it was produced synthetically and, as soda water, is widely used as a beverage, often lightly flavored, as well as a component of other beverages.
