What is "marzemino"

Marzemino is a red Italian wine grape variety that is primarily grown around Isera, south of Trentino. The wine is most noted for its mention in the opera Don Giovanni of Wolfgang Amadeus Mozart ("Versa il vino! Eccellente Marzimino!"). The vine ripens late and is susceptible to many grape diseases including oidium. Wine produced from the grape has a characteristic dark tint and light plummy taste.

Ampelographers have long theorized that the grape originated in northern Italy. Recent DNA profiling conducted at the research facility in San Michele all'Adige revealed Marzemino to have a parent-offspring relationship with the grapes Marzemina bianca in the Veneto, Refosco dal Peduncolo Rosso and Teroldego, from Friuli-Venezia Giulia and Trentino respectively, which gives further evidence to its likely origins in this region.
