The Dão wine region is perhaps the most prestigious in Portugal, a remarkable turnaround give the poor reputation it used have. South of the Douro and its famous Port vineyards, the Dão benefits from moderate to high altitudes, granite-rich soils and the weather break afforded by the Serra do Caramulo and Serra da Estrela. It is the historic home of Touriga Nacional and one of Portugal's oldest wine producing areas.
