club soda

club soda (countable and uncountable, plural club sodas)

2. (Canada, US) A carbonated beverage consisting mainly of carbonated water, with or without a few other minor ingredients such as potassium citrate.

   Hypernyms: soda, fizzy drink < soft drink < drink, beverage

   Near-synonyms: (broadly synonymous) carbonated water, seltzer water, seltzer, soda water, fizzy water

In American English (and possibly other varieties), a distinction is sometimes drawn between club soda and seltzer: a given brand will call a product seltzer when it contains nothing but carbonated water, but the product called club soda also contains a few other ingredients, although the products may be indistinguishable by taste and appearance.

While "club soda" and "soda water" are often used interchangeably, club soda is distinct because it has additional minerals.
