What is "rosso antico"

Rosso Antico is a dessert wine produced in San Lazzaro di Savena, Italy. It is produced by the infusion of 32 herbs macerated in alcohol (including rosemary, thyme and sage) and then added to a mixture of 5 different types of wine. The drink is ruby-colored and has a sweet-sour flavor with notes of citrus and vanilla. Its alcohol content is 17% and is recommended for consumption as an aperitif, served plain with a slice of orange. It is sometimes used as an ingredient in a Negroni cocktail, as a substitute for Campari.
