Club soda differs from sparkling mineral water in the way it gets its minerals, the minerals added, and carbonation source.
Rather than naturally occurring, carbonation is the result of carbon dioxide gas being added under pressure rather than naturally occurring.
Its flavor is enhanced by artificially adding minerals – including sodium bicarbonate, sodium citrate or sodium chloride, and disodium phosphate or potassium sulfate. As with sparkling water, the mineral content can vary between manufacturers, meaning taste will differ as well.
Club soda can be enjoyed in place of water or as a mixer in your favorite drink.
A major point to note is the high sodium content of club soda. Depending on your health and dietary restrictions, you may want to limit your daily intake of club soda.
