A variety of Portuguese origin, presumably autochthonous, it is classified as a wine grape. It is used for the production of red wines—both in blends to impart color and fruitiness, and for the production of varietal wines, particularly in the Dão region.
The variety is early-ripening and characterized by strong vine growth, which requires fertility control. The grapes are valued for the intense dark color of the berries, and wines made from them possess aromas of blackberry, ripe strawberry, and plum with a good balance of tannins and acidity.
The plant is considered delicate and highly sensitive to fungal diseases, in particular downy mildew, powdery mildew, and grey mold, which requires careful maintenance during cultivation.
