Bright, citrusy, and endlessly refreshing, this homemade grapefruit sparkling water is the kind of drink that makes you wonder why you ever reached for a store-bought can. A simple syrup made from real grapefruit juice and zest gives it a bold, natural flavor that no bottled version can quite match. The syrup comes together in just a few minutes on the stovetop ā no boiling required ā and after a short steep, the zest infuses every drop with that fragrant, slightly bitter citrus edge. Straining it smooth before combining with chilled sparkling water keeps the texture clean and the bubbles intact. Every single ingredient here is straightforward and naturally free of thickeners or additives, so there's no label-reading stress involved. Poured over ice with a fresh grapefruit wedge on the rim, it looks and tastes like something from a fancy brunch spot ā made entirely in your own kitchen.
