Quinta do Castelinho is an iconic property of the Douro, as referenced in the map of the Baron of Forrester in 1848. In 1903, the winemaker Batalha Reis writes in the journal O Commercio do Porto: "... the wine from Castellinho (...) has, when new, two characteristic that individualize this wine and imprint qualities of high value: a balsamic scent that intoxicates and a dry metalic sui generis background ... ". Years later, a new record is found in the book O Douro written by Manuel Monteiro (1911), accompanied by a photography of the time: "... where the nucleus of the famous Quinta do Castellinho is, whose name one reads in bold, bulging, huge characteres, over the whitewashed noble house with a hipped roof."
