Graham¦s wines come primarily from its own Quinta dos Malvedos near 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 de Vale de Malhadas, also supply Graham with finest quality grapes. All four 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.
