The recipe of the spritz calls for Prosecco, Aperol, and sparkling water. It's served over ice in a wine glass or lowball glass with an orange wedge garnish. To follow the original recipe and obtain a traditional Italian spritz cocktail, you don't have to change the order of the ingredients when making it. If you do so, the final result will change. Aperol is heavier than prosecco or white wine, so if you mix it immediately with the other ingredients, it deposits on the bottom, and it does not return the flavor or the color.
