With oenology by José Manuel Sousa Soares, this commemorative edition of Dalva will be limited to three thousand bottles, resulting from the important stocks of Port wine aging in the historic cellars of C. Da Silva. Porto Dalva Colheita 2001, whose harvest dates back precisely to the year in which the Douro region was acclaimed with the distinction of UNESCO, thus appears as a tribute from C. Da Silva to all the men and women who built and continue to build the Alto Douro Vineyard to this day.
