This grapefruit Aperol spritz has quickly become my favorite spritz! It combines grapefruit liqueur, Aperol, prosecco, a little sparkling water, and rosemary to create a light, airy, and layered cocktail that is utterly delightful. It's not overly sweet; it's lightly fruity and has lovely herbal notes from the rosemary.
Fill a wine glass with ice, and top with the grapefruit liqueur, Aperol, and prosecco. Top with sparkling water, bitters, and stir. Finish with a grapefruit wedge and rosemary sprig.
