This means the variety has grown for at least 900 years as cuttings from just one ancestral plant...

Huh? so some guy growing grapes 900 years ago, destroyed all his other plants, and rebuilt his vineyard from a single plant? And all his winemaking buddies, the weird raisin guy down the street, all got rid of their plants to use his one survivor? I don't think so...
