History and Etymology

Until World War II, carbonated water was referred to as soda water in the US because of the sodium salts it contained in an attempt to imitate mineral water. In the UK and Canada today, drink mixers sold as soda water or club soda contain bicarbonate of soda, giving them a specific flavor that sets them apart from carbonated water.

The term Seltzer water is a genericized trademark that derives from the German town Selters, known for its mineral springs. The term is practically unknown in Great Britain and most of the Commonwealth countries.
