Malvasia di Schierano

A black grape registered as its own distinct variety in Italy's national vine register (scheda 137) — not a synonym of Malvasia Nera Lunga or Malvasia di Casorzo, despite the shared "Malvasia" name. Used alongside Malvasia Nera Lunga (interchangeably, per the disciplinare) in Malvasia di Castelnuovo Don Bosco and in Collina Torinese.
