Grahams Natura is a Reserve Port produced from Symington owned organic vineyards at Quinta das Lages in the Rio Torto Valley & Vineyards in the Vale da Vilarica in Portugal's Upper Douro Valley. Situated at 150 and 350 meters above sea level, these vineyards benefit from well aerated and dry conditions, which in turn allows each vine to develop their own natural defenses.

Following organic cultivation guidelines and respecting the vineyards natural cycle, each vine finds its own yield level, producing smaller grapes with more concentrated fruits. The grape varieties used to make Grahams are a blend of traditional and typical varieties found in the Douro, such as Touriga Nacional, Touriga Franca, Tinta Roriz, Tinta Barroca and Tinta Amarela.
