What is the Difference Between Club Soda and Seltzer?

The main difference between club soda and seltzer lies in the mineral content and taste. Both are carbonated water, but they are processed differently and have distinct characteristics:

• Club Soda: This is water that has been carbonated by injecting it with carbon dioxide gas (CO2) and infused with added minerals, such as potassium sulfate, sodium chloride, disodium phosphate, and sodium bicarbonate. The minerals in club soda give it a slightly salty taste and enhance its fizz. Club soda is often used as a mixer for cocktails, especially those including gin or vodka.
• Seltzer: Seltzer is water that has been carbonated, but it generally doesn't contain added minerals. It is made similarly to club soda but has a plainer taste due to the absence of minerals. Seltzer can be used as a substitute for club soda in cocktail mixers.

In summary, club soda is carbonated water with added minerals, giving it a slightly salty taste and enhanced fizz, while seltzer is plain carbonated water without added minerals, resulting in a plainer taste.

Comparative Table: Club Soda vs Seltzer

The main difference between club soda and seltzer lies in the added minerals and sodium content. Here is a comparison table of the two:

Club soda is water that has been carbonated and infused with added minerals, giving it a slightly salty taste. Seltzer, on the other hand, is plain water that has had carbonation added to it, and it does not contain added salt. Both beverages can be used as mixers for cocktails, but club soda is more commonly used for this purpose.
