Imagine you’re at a party. Seltzer is that chill friend who shows up with a bottle of plain soda and says, “I brought bubbles, you bring the mixer.” It’s low-maintenance and up for anything. Club soda is the friend who brings a custom cocktail kit and insists on using a specific kind of tonic “for balance.” A little extra effort, but the result is usually smoother.
And let’s not forget tonic water—the wild cousin that actually has sugar and bitter quinine. That’s a whole different story. But for our two stars, the difference is subtle but real. It’s the difference between “fizz” and “smooth fizz.”
