Bright, citrusy, and endlessly refreshing, this homemade sparkling water is the kind of drink that makes plain seltzer feel like a distant memory. A quick grapefruit syrup ā made by gently warming sugar, water, fresh juice, and zest together ā gives every sip a punchy, sun-ripened flavor that no store-bought flavored water can match. The syrup steeps off the heat so the zest has time to fully infuse, and straining it leaves you with a beautifully clear, fragrant base. Stirring it gently into chilled sparkling water keeps the bubbles lively, so your glass stays effervescent right down to the last sip. Naturally free of grains and starches, this recipe is as clean and simple as a drink can get ā just real fruit, sugar, and water doing exactly what they should. Serve it over ice with a grapefruit wedge on the rim for a presentation that looks far more impressive than the effort involved.
