Kopke is one of the oldest and most historic Port Houses, and they also are well known for possessing one of the largest and most impressive libraries of Colheita Port in the Douro Valley. Essentially these are vintage dated Tawny Ports, so they spend years – if not decades – slowly maturing in cask before bottling, slowly increasing in complexity as the years pass. The origins of this iconic Port House can be traced back to 1636 when a German family named Kopke moved from Hamburg to Lisbo. Two years later, Christiano Kopke established a business in Oporto, as merchant and exporter of Portuguese products, including local wine. The purchase of a farm in the Douro, in 1781, marked the transition from a wine buying company to a major producer. Nearly 250 years later, Kopke remains a leader in the Douro Valley.
