Here’s the simplest way to think about it: all soda water is carbonated water, but not all carbonated water is soda water. It’s like all pugs are dogs, but not all dogs are pugs. Carbonated water is the big, happy family name for any water that has carbon dioxide gas dissolved into it. Soda water is just one specific member of that family—the one that shows up with a little added minerals like sodium bicarbonate or potassium sulfate.

Imagine you’re at a party with all the bubbly waters. Seltzer is the plain, no-fuss cousin who just shows up with plain bubbles. Club soda is the one who brings a tiny pinch of salt and minerals for a slightly smoother taste. And mineral water is the fancy relative who gets its bubbles straight from a natural spring, with its own unique mineral fingerprint.
Then there’s soda water, which is basically club soda’s twin—both have added minerals, but soda water often has a little more oomph in the flavor department. If you’ve ever had a gin and tonic or a whisky soda, you’ve probably tasted soda water without even realizing it.
