There are two grape varieties with this name:
The red grape variety (also I. P. 105, Pirovano 105) is a new cross between Moscato Rosso di Malaga x Pirovano 17 (Pinot Noir Précoce = Early Burgundy x Malvasia di Sardegna = Malvasia di Lipari). The cross was made at the research centre in Rome/Italy by the Italian breeder Alberto Piròvano (1884-1973). The vine is used as a wine grape and table grape. It was a crossing partner for some Conegliano varieties. No stocks were reported in 2016 (Kym Anderson).
The white grape variety originates from Portugal. The parentage is unknown. No stocks were reported in 2016 (Kym Anderson).
