Schiava Grossa | Red wine grape native to Italy, a member of the unrelated Schiava group of varieties. As its name suggests it is distinguished by big berries and big bunches; although new clones of Schiava Grossa bear smaller berries. It is the highest yielding of the Schiavas, with more delicate aromas and flavours and higher acidity. Schiava Grossa is a parent (along with Moscato d’Alessandria) of Malvasia del Lazio and (with Riesling) of Kerner. Given DOC regulations, it is difficult to find true monovarietals.
