Seltzer water and club soda are two widely available carbonated beverages, both either commonly consumed plain or used as ingredients in mixed beverages. While the terms "seltzer" and "club soda" are sometimes used interchangeably, subtle flavor differences make these two types of sparkling water useful for different purposes. Some cocktails that incorporate seltzer water include the Brandy Rickey and the New Orleans fizz. Seltzer can also be used for non-alcoholic beverages such as the egg cream. Some popular cocktails made with club soda are the mojito, the Singapore sling and the Tom Collins.

In the contemporary beverage marketplace, both seltzer and club soda are packaged very similarly, albeit with different labeling, usually in plastic bottles.Learn more about Soft Drinks
