Carbonated water, also known as sparkling water, SODA water, or seltzer water, is a type of water that has been infused with carbon dioxide gas. It is commonly referred to as SODA, which is an abbreviation of the term 'SODA water'. The term 'seltzer' is derived from the German word for sparkling water. Carbonated water has a distinctively bubbly and refreshing taste, and is often used as an ingredient in cocktails and other beverages. It can also be enjoyed on its own as a refreshing beverage.
