Having celebrated its 100th year of trading in 2013, Barros Port is undoubtedly one of the most prestigious companies producing and trading in Port. Much of their success comes from Colheita Ports - old Tawnies from a single year matured in cask for a minimum period of seven years. Their expertise in Colheita Ports has established them as the stand-out producer of this style. Barros leaves their Colheita Ports to mature in a cask until being hand bottled to order. The loss of wine from evaporation (known as the 'Angel's Share') is much higher in comparison to bottle aging. It is a sacrifice they are willing to make and one that helps them achieve unsurpassed quality in their Colheita wines. In June 2006, Barros was integrated into the Sogevinus Group who are growing the brand in international markets.
