Quinta do Infantado has been a leader in estate-bottled Ports since 1979. Until that time, all exported Ports had to be shipped in bulk to Vila Nova de Gaia, 60 miles west of the Douro Valley, where they were bottled and shipped. This practice effectively prevented small private producers from exporting their wines, since the cost of running an operation in another town was prohibitive for these vineyard owners. In 1986 the laws were changed. The Quinta is based in Pinhão, specifically in the subdistrict of Gontelho where the best Port vineyards may be found. The estate has been owned by the Roseira family since the end of the 19th century and is now managed by brother and sister, João Roseira. Their basic Ports are outstanding examples of elegance and richness.
