Refosco is a very old Italian family of dark-skinned grape varieties native to the northern Italian and neighbouring areas of Friuli, Gavi, Trentino, Istria, and Karst Plateau. The wines this grape yields can be quite powerful and tannic, with a deep violet color and a slight bitterness. On the palate, there are strong currant, wild berry and plum flavors. The wine can stand some aging (depending on variety), and after a period of four-to-ten years, it achieves a floral quality as well. The Refosco family have a very long history, but details of the early history are not clear. DNA analysis of Refosco dal Pedunculo Rosso has revealed Marzemino, another ancient variety of northern Italy, as one of its parents. Some authorities have suggested that Mondeuse noire, which is primarily found in the Savoy region in eastern France, is identical to Refosco dal Pedunculo Rosso due to the similarity of the wines.
