- Started in 1756 when a region along the Douro River was demarcated for the production of Port Wine using 335 Pombaline Markers (Granite Stone Markers bearing a number). - Located in the Douro region of Baixo and Cima Corgo on the left side of the river Douro at an altitude about 300m above sea level, Quinta Santa Eufemia continues to be managed by the Carvalho family. - Quinta Santa Eufemia also does not sell in chains or large stores. Their approach to selling is personalized; thus they sell in boutique stores where there is more attention to detail for the customers selecting that special bottle of wine. - Offers Port Wine and Douro Wine.
