This white grape variety comes from Italy. The name is derived from the elongated grape shape (pigna = pine cone). Synonyms are Aglionzina, Alionzina, Grechetto di Todi, Grechetto Gentile, Greco Bianco di Rogliano, Occhietto, Pallagrello di Avellino, Pallagrello di Caserta, Pallarella, Piedimonte Bianco, Pignoletta Bianca, Pignoletto Bolognese, Pignolino, Pulcinculo, Rébola, Ribolla Riminese, Strozzavolpe and Uve Pignole. It should not be confused with Graševina (Welschriesling), Grechetto di Orvieto, Pallagrello Bianco (Piedimonte Bianco), Pignolo, Pinot Blanc or Ribolla Gialla, despite the synonyms or morphological similarities that seem to indicate it. According to an unverifiable hypothesis, Pignoletto is a descendant of the "Pino Lieto" (happy fir) mentioned by Pliny the Elder (23-79). The very old variety was first mentioned in 1654 as "Uve Pignole". According to DNA analyses, the varieties Grechetto di Todi (Umbria) and Rébola or Ribolla Riminese (Emilia-Romagna) are identical. There is a parent-offspring relationship with Grechetto di Orvieto (Umbria), which until then was considered a clone of Pignoletto. There is also a genetic relationship with Spergola.
