The white grape variety originates from Italy. Synonyms are Altruga, Altrugo, Altrugo de Rovescala, Altrugo di Rovescala, Artrugo, Barbesino, Barbesino Bianco, Barbsin Agglomerato, Ortrugo de Rovescala and Trebbiano di Tortona. Nothing is known about the parentage or a possible connection to the Grignolino (Barbesino) variety. The very late-ripening vine is susceptible to grape berry moth infestation and grape rot. It produces straw-yellow to greenish, tangy white wines with a neutral aroma, which are often used for the production of sparkling wines. The variety was first mentioned in 1881 under the name Artrugo. By the end of the 1960s, it was almost extinct, but could be revived. The vine is grown almost exclusively in the province of Piacenza in Emilia-Romagna, where it is permitted in the DOC wines Colli Piacentini and Ortrugo dei Colli Piacentini. There is also a small stand in the Oltrepò Pavese area in Lombardy. The Italian cultivated area in 2016 totalled 709 hectares (Kym Anderson).
