Dow’s grapes come from five of the finest vineyards in the Douro valley – Quinta do Bomfim, Quinta da Senhora da Ribeira, Quinta do Santinho, Quinta de Cerdeira & Quinta da Fonte Branca– with a total of 133 hectares under vine. These five estates form the backbone of Dow’s greatest Ports. Three wineries, two large ‘state of the art’ wineries at Bomfim and Sol and one small ‘specialist’ winery at Senhora da Ribeira, permit Dow’s to be the largest buyer of premium quality grapes in the Douro and represent a unique investment in diversified and specialised winemaking for the pursuit of quality. Dow’s Vintage Ports are powerful and austere when young but age superbly with great purity of style. The wines have a firm tannic structure with spicy black-pepper and bitter chocolate flavours. The aromas are of violets when young, maturing into cinnamon with age. These Ports develop a superb racy elegance with maturity while maintaining balanced richness with its characteristic dryness.
The Douro valley is the home of Port production and is one of the oldest demarcated wine regions in the world. The vineyards follow a band of Schist along the valley rising up in steep terraced slopes from the river. Upstream lies Spains Ribera del Duero. Increasingly, unfortified wines are produced here, but it is really for great vintage port that the region is known.
