Malvasia Nera Lunga

A black grape registered as its own distinct variety in Italy's national vine register (scheda 363) — not a synonym of Malvasia di Schierano or Malvasia di Casorzo, despite the shared "Malvasia" name. Used alongside Malvasia di Schierano (interchangeably, per the disciplinare) in Malvasia di Castelnuovo Don Bosco and in Collina Torinese.
