Here’s the thing: seltzer is basically just plain carbonated water. Nothing else. Think of it as the minimalist of the fizzy world. It’s just water with carbon dioxide forced into it under pressure. That’s it. No extras. No drama.
Soda water, on the other hand, is seltzer’s slightly fancier cousin. It usually has some minerals added. Think sodium bicarbonate, potassium sulfate, or sodium chloride. Sounds fancy, right? It’s basically just a pinch of salt and a few other rocks for flavor and mouthfeel.
Why add those minerals? To make the bubbles feel softer, a bit more rounded. Seltzer bubbles are sharp and aggressive. Soda water bubbles are like a gentle hug from a penguin. You can almost taste the difference.
Wait, What About Club Soda?
Oh, you had to bring that up, didn’t you? Club soda is basically a brand name for soda water. They’re usually the exact same thing. But some club sodas add a little more sodium than your standard soda water. It’s a bit like calling all tissues “Kleenex.” Technically wrong, but nobody yells at you for it.
So, in most bars, “soda water” and “club soda” are swapped out like they’re long-lost twins. If you’re at a fancy cocktail place, they might use one with a specific mineral blend. But for you and me? It’s basically the same fizzy stuff.
