Bright, citrusy, and endlessly refreshing, this homemade sparkling grapefruit drink is the kind of thing you'll want to keep in the fridge all week. A quick stovetop syrup made from real grapefruit zest and juice gives it a depth of flavor that no store-bought version can match ā floral, slightly tart, and just sweet enough. 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. Folded gently into chilled sparkling water, it stays bubbly and light right up until the last sip. Every single ingredient here is straightforward and naturally free from nuts of any kind, so there's zero guesswork about what's actually in your glass. Serve it over ice with a fresh grapefruit wedge on the rim and it looks as good as it tastes ā effortlessly elegant for a weeknight or a weekend gathering alike.
