Club soda is a variety of carbonated water. It is water to which carbonation and potassium bicarbonate and/or potassium sulfate has been artificially added in order to enhance its flavor. It is very similar to seltzer water, but seltzer water does not include the added mineral content (and is very similar to unprocessed mineral water). Mineral water has undergone less processing and acquires its mineral content from its geologic source rather than having it added later.
