In 1978, Fonseca acquired Quinta do Panascal, whose reputation goes back to the 18th century, when wines from the Tavora Valley in Cima Corgo, where the vineyard is located, were considered among the finest-quality wines of Portugal. The company later expanded the vineyard by acquiring the neighboring Quinta do Val dos Muros. At present, 109 of its 188 acres are planted, principally to Touriga Nacional, Touriga Franca and Tinta Roriz. In high-quality but non-declared vintages, fruit from Quinta do Panascal is used to produce a single-quinta vintage Porto.
