Let’s keep it simple, friend. If you want a clean, sharp fizz with no taste? Call it seltzer. If you’re making a cocktail? Reach for club soda.
If you want bitter, sweet, and dangerously delicious? That’s tonic water. If you want to pretend you’re on vacation in Italy? Go for mineral water.
And if you just want to sound like you know what you’re talking about? Just call it all sparkling water and smile. Nobody will argue. Probably.
