Club Soda

(n.) Carbonated water with added minerals—commonly sodium bicarbonate or salt—club soda was designed to approximate mineral water, which is often naturally fizzy, but can carry a hefty price tag. English chemist Joseph Priestly invented the process of carbonation in 1767, when he realized that the carbon dioxide produced during the fermentation of beer could be infused into water. Soon after, Jacob Schweppe, a Swiss watchmaker, figured out how to manufacture carbonated water (which has no added minerals) and club soda. These products would become the cornerstone of the Schweppes Company, which is still in existence today. The added salt or sodium bicarbonate helps to mitigate the sour flavors from the carbonic acid, a byproduct of carbon dioxide.
