What is "club soda"?

Club soda is a carbonated beverage that is made by adding carbon dioxide to water. It is similar to other carbonated drinks such as soda or seltzer water, but contains added minerals such as sodium bicarbonate, sodium chloride, and potassium sulfate. These minerals give club soda a slightly salty taste and can help to enhance the flavor of other drinks when used as a mixer. Club soda can be consumed on its own or used as a mixer for cocktails such as gin and tonic or Tom Collins. It is often used in recipes as a leavening agent or to add bubbles to baked goods. Club soda is a popular alternative to sugary soft drinks and is often consumed as a part of a healthy diet.
