The red variety comes from Trentino-Alto Adige ( Italy ). The name probably derives from the Valle Lagarina in Trentino. Synonyms include Blue Lagrein, Burgundi Lagrein, Lagrain, Lagrino, Lagroin and Land Blacks. A "Roter Lagrein" (wine) is called by the Tyrolean peasant leader Michael Gaismair (1490-1532) around 1525. The earliest mention of a variety Lagrein in a document from Gries near Bolzano from 1318 refers to a white wine. Until the 18th century, "Lagrein" usually meant a white wine. Its identity is not clear, because it could be Savagnin Blanc ( Traminer ) or to Lagarino Bianco have acted.
