Bright, citrusy, and endlessly refreshing, this homemade grapefruit sparkling water is the kind of drink that makes you feel like you're sitting on a sun-drenched patio no matter where you actually are. A simple syrup made from real grapefruit zest and juice gives it a depth of flavor that no store-bought version can touch ā floral, slightly bitter, and perfectly sweet all at once. The whole thing comes together with just a handful of ingredients: sugar, water, fresh grapefruit, and chilled sparkling water, so there's nothing hidden or complicated to worry about. Steeping the zest into the warm syrup is the secret step that makes the citrus flavor bloom before you ever pour a drop. Once you strain it and gently fold in the bubbles, you've got a gorgeous, naturally wheat-free drink that works as a mocktail, a brunch staple, or just a fancy way to stay hydrated. Garnish with a fresh grapefruit wedge and serve over ice for a presentation that looks far more impressive than the effort it took.
