Tinto Cão is a dark thick-skinned red grape variety indigenous to Douro Valley wine region of Portugal. It is one of the oldest grapes documented in northern Portugal since the 1600s. The name of the grape in Portuguese means "red dog" and it is traditionally used in the Port wine blend together with Touriga National, Touriga Franca and Tinta Roriz (Tempranillo). Tinto Cão is as well planted in the Dão wine region where is often vinified alone and gives very elegant and floral wines often compared to those of Burgundy of France. The small and dense clusters of small berries deliver long-lasting wines with crisp tartness and a velvety texture, which can sometimes be hard and austere when young but develops great finesse with age. The grape is becoming increasingly popular especially from the Dão region.
