Here’s if you remember nothing else: seltzer is plain carbonated water. Sparkling water is naturally fizzy from a spring. Everything else—club soda, tonic, flavored seltzers—is just playing dress-up. And drink what you love, seriously. I won’t shame you for buying the store brand.
But if you’re at a party and someone asks, you can now drop some knowledge with a smirk. Just don’t be that person who corrects everyone’s drink order. (Unless they ask. Then go off.)
