Founded in 1638 by Christiano Kopke and his son, Nicolau Kopke, the House of Kopke is the first and oldest port house. The Kopke cellars are located in the "Entreposto de Gaia", where the port under the most favorable conditions matures in traditional wooden barrels. This 10 year old Tawny is a marriage of some wines and aged on average 10 years in wooden barrels, making this port are getting pretty brown-tawny color.
