What is a popular non-alcoholic mixer for cocktails?

Club soda is a popular non-alcoholic mixer for cocktails because it is a carbonated water that provides effervescence and dilutes drinks without adding sweetness or additional flavors. This characteristic makes it a versatile choice that can enhance the texture and refreshing quality of cocktails while letting the flavors of the other ingredients shine through.

Many classic cocktails use club soda to add fizz, such as a spritzer or a mojito. Additionally, club soda can be used in non-alcoholic drinks, making it a staple in bars and restaurants for those who prefer or require a non-alcoholic option. Its neutral flavor complements fruit juices and spirits alike, making it a valuable component for both traditional and modern cocktail recipes.
