In the mid-1800s, Cornalin was one of the most common indigenous grape varieties on a par with Fumin and just below the Orious family. According to early ampelography studies for the identification and classification of Aosta Valley grapevines (1833-1838) the area between Saint Vincent and Verrayes was identified viticulture zone area with the widest distribution of this vine. As with other native vines, the arrival of fungal diseases (Oidium, Peronospora) and of Phylloxera led to it being abandoned and almost its extinction. Only the meticulous work of recovery and selection of the remaining specimens enabled us to start planting this vine again. Cornalin is a vine of absolute value and great personality.
