Ortrugo
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. 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.
