Bright, citrusy, and endlessly refreshing, this homemade sparkling drink is the kind of thing that makes plain water feel like a distant memory. A simple grapefruit syrup ā made by gently warming sugar, water, fresh zest, and juice together ā gives every sip a bold, tangy depth that no store-bought version can quite match. The syrup steeps off the heat so the zest has time to fully infuse before being strained out, leaving behind a beautifully clear, fragrant base. Stirred gently into chilled sparkling water, it keeps its fizz and delivers that satisfying effervescence in every glass. For anyone navigating ingredient labels on flavored drinks and sodas, making your own means you know exactly what's in it ā just sugar, water, and real grapefruit. Serve it over ice with a fresh grapefruit wedge and it looks as good as it tastes, whether you're hosting brunch or just treating yourself on a warm afternoon.
