Ortrugo is a white Italian wine grape variety that is grown in the Piacenza hills of the Emilia-Romagna region of north central Italy. Here the grape is often blended with Malvasia in the DOC white wines of the area.^[1] According to wine expert Oz Clarke, the grape has moderate acidity with high alcohol potential and often contributes a deep yellow color to the wine. In some regions the grape is used in slightly sparkling frizzante and fully sparkling spumante wines.^[2]

Ortrugo is a permitted variety in the Denominazione di origine controllata wines of the Colli Piacentini DOC covering more than 3,600 hectares (9,000 acres) in the hilly Piacenza region.
