Bright, citrusy, and endlessly refreshing, this homemade sparkling grapefruit drink is the kind of thing you'll want to keep in the fridge all week. Store-bought flavored sparkling waters and sodas often sneak in natural flavors, emulsifiers, or other additives that can be surprisingly hard to vet ā making a from-scratch version genuinely worth the effort. Here, a simple syrup built from real grapefruit juice and zest does all the heavy lifting, and every single ingredient is exactly what it says it is. The syrup steeps gently off the heat so the zest can deepen the flavor without any bitterness, then gets strained clean before meeting the bubbles. Stirring the sparkling water in just once or twice keeps the carbonation lively, so each glass stays crisp and effervescent all the way to the bottom. A wedge of fresh grapefruit on the rim makes it feel like something you'd order at a nice brunch spot ā except you made it yourself in about twenty minutes.
