Tinto Cão
Tinto Cão is a red grape associated with Douro blends and also recorded in Dão. The Wines of Portugal profile describes a late-ripening, low-yielding vine.
Identity and growing conditions
Thick skins contribute colour and tannin in the source account. Low yields create an economic constraint, but the profile’s prediction of disappearance is not treated as a verified conservation assessment.
Wine styles and uses
The source describes structured, floral wines and blending with other Douro grapes. Historical recommendations are not presented as current legal requirements, and no fixed blend proportion is assigned.
