The red grape variety originates from Italy; it is one of the numerous Lambrusco varieties. Synonyms are Aglianico Dolce Précoce, Anrè, Anrè Grossolano, Badino, Caruét, Cascarello, Corva, Croetto, Crova, Covra Astigiana, Crova Nera, Crovet, Crovin, Farinellona, Grosso Covarevo, Lambrusa, Lambrusa di Alba, Lambrusa Saluzzese, Lambrusca, Lambrusca Viola, Lambrusco di Alessandria, Moretto, Neretto di Alessandria and Stupèt. It should not be confused with the French variety César or the Piedmontese variety Corva, despite the synonyms or morphological similarities that seem to indicate it.According to DNA analyses carried out in 2020, it comes from a presumably natural cross between Crovin x Neretto di Marengo. The Brachetto Migliardi variety comes from a cross with Malvasia Aromatica di Parma.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
