Graham’s wines come primarily from its own Quinta dos Malvedos, Quinta do Tua and Quinta das Lages in the Rio Torto. Two others, privately owned by a member of the Symington family, Quinta da Vila Velha and Quinta do Vale de Malhadas, also supply Graham with the finest quality grapes. All five Quintas are among the best in the upper Douro valley. Graham’s also buys grapes from selected farmers in the finest districts. Some of these farmers have been selling their grapes to Graham’s for generations.
Traditional Portuguese grape varieties are harvested by hand in the fall and fermented for a short period of time before the addition of 100% neutral grape spirit alcohol. This stops the fermentation and preserves the wine’s natural grape sugars. Graham’s Fine Ruby & Tawny Port are aged in oak casks for an average of three years and then bottled ready to drink.
