Rossese Bianco is a grape variety originating from the Cinque Terre and is grown in a small area of the Langhe but primarily in Liguria. Historically, varieties of white grapes called Rossese were widely cultivated in Liguria, where Rossese Bianco was part of the blends used in the Cinque Terre wines, as well as in Piedmont, near Alba and Mondovì. Rossese Bianco seems to have arrived in the Langhe in the late 19th century and was rediscovered in the mid-1970s in old vineyards in Monforte d’Alba, where it has been certified as being present for a considerable time, earning recognition as a native Piedmontese variety. The wine made from its grapes achieved Langhe DOC Rossese Bianco status in 2011.

Currently, the cultivation of Rossese Bianco is limited to the municipalities of Sinio and Roddino in the Alta Langa. The name Rossese Bianco comes from the intense amber or even pinkish hue of the fully ripe grapes when exposed to the sun. Other grapes called Rossese Bianco exist in both eastern and western Liguria, but they do not always have phenological similarities to the Rossese Bianco of the Langhe.

This is a moderately vigorous grape variety with good but somewhat inconsistent productivity. It produces sugary grapes with good acidity and very small berries. Its cluster is large, broad, conical, with one, two, or three well-developed wings, and moderately compact. The berries are small, spherical, and tend to be very pruinose. The grape ripening period is between late September and early October.
