Croatina is a red Italian wine grape variety that is grown primarily in the Oltrepò Pavese region of Lombardy and in the Province of Piacenza within Emilia Romagna, but also in parts of Piedmont and the Veneto. In the Oltrepò Pavese, in the hills of Piacenza, in Cisterna d’Asti and San Damiano d’Asti (Province of Asti), and in Roero this variety is called ‘Bonarda’. It should not, however be confused with the Bonarda piemontese, which is an unrelated vine.[1][2] In the Piedmont region, it is sometimes blended with Nebbiolo in wines of Novara and Vercelli Hills.[3]
