It is one of the oldest and most widespread varieties of table grapes, which is why it has taken to many synonyms during the years. It is known as Pergolone in Abruzzo, Inzolia Imperiale in Sicily, Menavacca in Puglia, Calabria and Campania, Dattier de Beyrouth in France, Afouz Ali or Bolgar in Bulgaria, Aleppo in Romania, Rasaki on the Aegean islands. It is certainly of Eastern origin, perhaps from Syria. It is however not well known how and when it reached Italy, perhaps in ancient times, even before the vulgar era. Few vines have such a similar record of seniority of cultivation and such an extended area of diffusion, which is identified in almost all the wine-growing countries of the Mediterranean.
