Want to see the difference for yourself? Pour a glass of seltzer and a glass of club soda side by side. Take a sip of each. The seltzer will feel lighter and more “spiky” on your tongue. The club soda will feel rounder, almost creamy by comparison.
Now check the bubbles. Club soda’s minerals keep the bubbles bigger and more persistent—they hang around like guests who don’t know when to leave. Seltzer bubbles are smaller and fizzle out faster, like me at a karaoke bar after one song.

Which One Should You Buy?
Here’s the cheat sheet: For cocktails: club soda. For plain drinking or mixing with juice: seltzer. If you’re on a low-sodium diet, seltzer is your hero. If you want a little extra flavor in your bubbly water without adding syrup, grab the club soda.
But honestly? Most people can’t tell the difference in a blind taste test. I’ve done this at parties (yes, I’m fun at parties), and about 70% of people guess wrong. So don’t sweat it too much.
