Club Soda vs. Seltzer Water: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 25, 2023
Club soda vs. seltzer water: Club soda contains minerals; seltzer water is just carbonated water.

Key Differences

Club soda and seltzer water are both carbonated beverages that are commonly consumed on their own or as mixers in drinks. Club soda is infused with mineral salts like sodium bicarbonate, sodium chloride, and potassium sulfate. These minerals give it a distinct taste. On the other hand, seltzer water is simply water that has been carbonated, without the addition of any minerals or flavorings, making it a more neutral option in terms of taste.
The mineral content in club soda can sometimes lend it a slightly salty taste. This taste profile makes it a popular choice for cocktails, as it can enhance or balance the flavors of certain drinks. Seltzer water, being just carbonated water, has no additional flavors. Its clean and neutral taste makes it a versatile mixer, as well as a refreshing drink on its own.
People often use club soda and seltzer water interchangeably because of their similarities, but the mineral content is what sets them apart. Club soda can be slightly alkaline due to its mineral content, whereas seltzer water will have the pH of the water it was made from.
Another point to consider is health implications. Since club soda has added minerals, it may contain sodium. For those watching their sodium intake, it might be better to opt for seltzer water. Both beverages, however, are calorie-free and sugar-free, making them healthier alternatives to sugary sodas.
In cooking, the effervescence of both club soda and seltzer water can be used to make light and airy batters. While seltzer water provides no additional flavor, club soda might introduce a slight mineral taste to the dish.
