The difference between club soda, seltzer water and tonic
Seltzer: Seltzer is simple carbonated water with no flavor. It is what you use to remove ketchup stains from your shirt. Club soda: Unlike seltzer, mineral-like ingredients are added to club soda to enhance the flavor. Tonic: Tonic water is a bitter drink, making use of quinine for a flavor that pairs particularly well with gin.
