Rossese bianco is a white Italian wine grape variety that is grown around the communes of Roddino and Sinio in the Langhe region of the province of Cuneo in Piedmont. While sharing the name Rossese with several Italian varieties (including Rossese di Dolceacqua, Grillo and Ruzzese), DNA profiling has shown that all these varieties have unique genetic profiles and appear to have no close relationship to each other.[1]
Ampelographers believe that the name Rossese came from a description of the intense color of the Rossese berries with the many varieties that are known as Rossese having skin colors that range from deep red to pink to dark gold after veraison.[1]
