Seltzer is the party chameleon. It shows up in everything—from LaCroix to seltzer makers like SodaStream. You can drink it straight, mix it with juice for a “mocktail,” or even use it in pancakes to make them fluffy (don’t judge, it works). Tonic is the snob of the sparkling world. It only really shines in one role: the classic Gin and Tonic or as a bored mixer for vodka, sometimes with a lime wedge for company.
If seltzer is a friendly golden retriever, tonic is that fancy cat who only lets you pet it if you’re holding a lime. Both have their place—just know which one you’re grabbing.
A Quick Cheat Sheet for Your Next Party
Picture this: you’re at a BBQ, and someone says, “Grab me a sparkling water.” Do you hand them a can of seltzer or tonic? Always seltzer. Unless they’re a mysterious person wearing sunglasses at night—then maybe they want tonic. Also, if the drink tastes weirdly bitter and sweet, it’s tonic. If it tastes like nothing with bubbles, it’s seltzer. If it tastes like regret and a hangover, it’s probably just club soda (which is another story for another day).
