Bright, citrusy, and endlessly refreshing, this homemade sparkling grapefruit drink is the kind of thing that makes you wonder why you ever reached for a store-bought can. A simple syrup made with fresh grapefruit zest and juice is the secret here ā simmering it low and slow pulls out every bit of that floral, tangy flavor before it ever hits the glass. The syrup gets strained smooth and then gently combined with chilled sparkling water so you keep all that satisfying fizz intact. Every ingredient in this recipe is naturally free from peanuts and tree nuts, so there's no label-scanning required ā just clean, simple components you can feel good about. It's a beautiful option for entertaining, too, since a garnish of fresh grapefruit slices makes it look far fancier than the effort involved. Serve it over a big glass of ice and let the bubbles do the rest.
