The Alto Douro Wine Region, located in north-eastern Portugal, is one of the world's most iconic wine-producing regions, where viticulture has been practised for over two thousand years. In 1756, it became the world's first officially demarcated wine region, established to regulate the production of Port wine. In 2001, it was inscribed as a UNESCO World Heritage Site in recognition of its unique cultural landscape. Shaped by the Douro River and its steep schist hillsides covered with terraced vineyards, the region offers a remarkable blend of heritage, natural beauty and tradition. A visit to the Douro provides the opportunity to explore historic wine estates (quintas), discover the winemaking process, sample outstanding wines, and enjoy breathtaking panoramic viewpoints. While internationally celebrated as the birthplace of Port wine, the Douro is equally renowned for its exceptional DOC Douro wines, including reds, whites and rosés. These are produced from an extraordinary range of indigenous grape varieties, such as Touriga Nacional, Touriga Franca, Tinta Roriz, Rabigato, Gouveio and Viosinho. The diversity of soils, altitudes and climatic conditions across the Douro's three sub-regions gives rise to an impressive variety of wine styles, making it an essential destination for wine enthusiasts and lovers of wine tourism.
