In 1820, William and John Graham were still textile merchants, who accepted 27 barrels of port as payment for their textiles. They decided to start making Port themselves in the Douro Valley. In 1890 they started their own vineyard; in that time very progressive. All grapes still come from their own vineyards. This 10-year-old Tawny is a blend of their best matured Port. The barrels made in their own cooperage are matured for at least 10 years in their own cellars.
