Soda water is the cool, slightly salty cousin of the sparkling water family. It’s made by injecting carbon dioxide into water, but here’s the kicker: it usually has added minerals like sodium bicarbonate or potassium sulfate.
That tiny pinch of salt gives it a rounded, less sharp taste. Imagine a plain cracker versus one with a little salt on top—it’s subtle, but your brain knows the difference.
You’ll find soda water in most cocktail recipes, like a gin and tonic or a whiskey highball. Bartenders love it because it doesn’t fight with the booze; it just gently lifts the flavors.
