William Offley founded the eponymous wine merchant in London in 1737, and soon began importing and bottling Port. By 1787, Offley was described as ‘one of the most considerable English houses at Porto.’ The house became famous for its association with Joseph James Forrester, later the Baron of Forrester, who came to Oporto in 1831 and became famous for mapping the Douro, and for painting many of its landscapes. Since 1997, Offley has thrived under the ownership of Sogrape and their best wines come from prime sites in the Cima Corgo region.
