Ambrogino is an Italian aperitif cocktail that hails from Turin. It combines Rabarbaro Zucca—bitter but approachable amaro flavored with rhubarb—Campari, vanilla syrup, and a dash of soda water. To make the cocktail, Zucca amaro, Campari, and vanilla syrup are shaken with ice.
The mixture is then strained into a cocktail glass filled with ice. To finish, the drink is topped with a splash of soda water. It is traditionally garnished with an orange slice. It is a signature cocktail at Zucca Bar in Turin, and it is named after St. Ambrose, the patron saint of Milan.
