The important port wine house in postage (Portugal) has emerged from various port wine companies throughout its history. The founder was the Scotsman Andrew James Symington (1863-1939), who immigrated in 1882. He started his career at the port wine company Warre’s (with Quinta da Cavadinha) and later became a partner in this company. At that time, George Warre owned the majority of the port wine company Dow's Port (with Quinta do Bomfim and Quinta da Senhorada Ribeira). In 1912, Symington acquired a stake in Dow's, while Warre bought back part of the family-owned company. The Symington family was responsible for production and the Warre family for sales and distribution. In 1961, Warre sold the remaining stake in the Symingtons, which now included 100% of Dow.
In 1970, W&J Graham’s (with Quinta dos Malvedos) was taken over as the third port company together with the sister company Smith Woodhouse . It continued with Gould Campbell and the last one with Quinta do Vesuvio in 1989. A partnership with Quinta de Roriz owned by João van Zeller, who is distantly related to the family, was resolved by mutual agreement in 2008. But there is no port wine brand called Symington, the products are produced under the names of the companies. Each of them has its own stocks.

For gold) has been made from the indigenous varieties Touriga Nacional (80%), Touriga Franca, Tinta Roriz ( Tempranillo ) and Tinto Cao blended and marketed under the "P + S" label (Prats and Symington). This is a joint creation with Bruno Prats, the former owner of Château Cos d'Estournel,
In the 1960s, the three cousins Ian, Michael and James Symington introduced new techniques.
