A Spritz is an Italian wine-based cocktail, commonly served as an aperitif in Northeast Italy. It consists of prosecco, digestive bitters and soda water. Since 2011 Spritz is an IBA official cocktail, initially listed as "Spritz Veneziano" then simply as "Spritz". Aperol traces its roots back to Padua, Italy. The aperitivo was created in 1919 while the Spritz was born during the period of the Habsburg domination in Veneto in the 1800s.
Add the prosecco, Aperol and club soda to a wine glass filled with ice and stir.
Garnish with an orange slice.
