Quinta do Infantado grows 46 hectares of vineyards in Covas do Douro, 100% letter A, the highest official classification in the Douro Demarcated Region. 12 ha in certified organic viticulture and 34 ha in integrated production, favoring sustainable viticulture. The soils are schist and poor. The vines result from the mass selection of more than 20 Douro varieties, between white and red, planted in all expositions and altitudes between 150m and 350m.
It is this viticultural diversity that allows Quinta do Infantado to make so many different wines without manipulation.
Serra de Baixo is the oldest vineyard with more than 100 years of age.
Other parcels of very old vines are located in Vale de Moinhos, Serra de Cotas, Lapa and Castelos. In the latter, several very old coins were discovered during planting in the beginning of the 20th century, strengthening the theory that this was the original location of the village of Covas do Douro.
In the seventies, some vineyard parcels were replanted in Vale de Moinhos, Castelos, Lapa and Barreiros.
In 1981 and 1982 Serra de Cima was planted. At the end of the eighties, after Portugal’s entry into the EEC, today the EU, Serra Douro was planted and Serra de Cotas were replanted.
Finally, the Pousado was replanted in 1998, the youngest vineyard, already over 20 years old.
