Spritz is produced by adding a drop of bitters to Sparkling wine.
Spritz has citrusy flavors of orange, lemon, and grapefruit. Meanwhile, the notes of rhubarb and gentian roots that come from the drop of bitters create a bittersweet and herbal taste.
Prepare filling a wineglass or old-fashioned glass with ice and pour this Spritz over. Garnish with an orange slice and serve.
