Quinta do Vallado estate, now in its sixth generation, has been family-owned since 1716 originally owned by the legendary Doña Antonia Adelaide Ferreira. Today the winery is owned by João Ferreria Alvares Ribeiro, Francisco Ferreira and Francisco Olazabal. It is one of the oldest and most famous “Quintas” in the Douro region. Two thirds of the vineyards are planted in terraces with a single row of vines and pruned according to the double cordon system. The old vines, which make up almost 40% of the vineyards are at least 80 years old. A new state-of-the-art winery was built in 1997 and a newly built, ultra-modern hotel was completed in 2012 making Quinta do Vallado a travel destination in the Douro Valley.
