Bright, citrusy, and genuinely refreshing, this homemade sparkling drink is the kind of thing that makes you wonder why you ever reached for a can. A simple grapefruit syrup ā made by gently dissolving sugar with fresh grapefruit juice and zest ā forms the flavor base, and the whole process is low-effort and completely approachable. Because the syrup is steeped rather than boiled, it stays delicate and fragrant instead of turning bitter or overly sweet. Store-bought flavored sparkling waters can be a minefield of hidden additives and fermented flavorings, so making your own from scratch gives you full control over every ingredient. The syrup gets strained clean before the sparkling water goes in, so you get a beautifully clear, jewel-toned drink with no cloudy bits or off flavors. Poured over ice with a wedge of grapefruit on the rim, it looks like something from a nice restaurant ā but it comes together right in your own kitchen.
