Duca San Felice is the name of the oldest vineyard owned by the Librandi family and the last one planted by Raffaele Librandi, the father of Antonio and Nicodemo.  This vineyard is situated in the heart of the Ponta territory, which is considered one of the oldest and most important crus of the classic Cirò area.  It is made entirely from Gaglioppo, a key indigenous variety that is thought to have been introduced from Greece to southern Italy around the same time as Aglianico.
