3⁄4 oz Aperol
3⁄4 oz Elderflower liqueur, St. Germain
3⁄4 oz Lime juice
1⁄2 oz Rosemary syrup
2 oz Sparkling white wine
Combine first 4 ingredients, shake with ice, strain into glass. Top with sparkling wine.
Rosemary syrup hack: use regular syrup and a couple sprigs of rosemary. Put both in the shaker before shaking. Note that this will require a double strain.
