Club soda is carbonated water that contains added minerals, such as sodium bicarbonate and potassium sulfate. It's similar to seltzer and sparkling water but has a slightly saltier taste due to these minerals. Think of it as carbonated water with a bit of extra flavor. It's often used as a mixer in cocktails and other drinks. The minerals can enhance the taste and effervescence of the beverage. It's a popular choice for those who want a fizzy drink without the sweetness of soda.
