Casa Ferreirinha is one of the most historic and respected wineries in Portugal’s Douro Valley, closely associated with the legacy of Dona Antónia Adelaide Ferreira, a pioneering figure who played a major role in the development of the region’s wine industry in the 19th century. The winery was formally established in 1952, but its roots date back to the extensive vineyard holdings and wine trade built by the Ferreira family over generations.
