The variety is autochthonous to the Douro and Dão regions of Portugal. The vine is characterized by vigorous shoot growth with low yields. The variety is of the mid-late maturity period, has small compact bunches and small berries with thick dark blue skin covered with a dense waxy bloom.
The plant is sensitive to wind and is prone to flower abortion and millerandage. It possesses relative resistance to powdery mildew and a number of fungal diseases. The grapes are characterized by a high concentration of tannins and aromatic substances, which provides the wines with deep color, powerful structure, and intense aroma.
