Okay, I have to bring up the annoying cousin: club soda. People mix it up with seltzer all the time. It’s not the same!
Club soda is artificially carbonated water that has added minerals (like potassium bicarbonate or sodium citrate) to mimic natural sparkling water. It often tastes a little “saltier” or more “mineral-y.”
So club soda is seltzer with a makeover and a bad attitude. It’s usually used for cocktails (hello, gin and tonic) because those minerals help preserve the bubbles and taste less flat.
