W. & J. Graham's, or simply Graham's, is a producer of port wine. It is one of the most important of the port names and it is necessary for Graham's to declare a vintage for the year to be considered vintage by the port industry. Founded in 1820 as a consequence of the Graham family firm receiving a load of Portuguese wine as payment for a debt, the Graham's port business continues to operate today under the ownership of the Symington Family Estates who purchased the brand in 1970. As well as vintage port, Graham's produces a range of wines, including Six Grapes, a reserve port, Quinta dos Malvados, named after the estate purchased by the company in 1890, and various single harvest ports, including the 1882 Ne Oublie Tawny, named after the Graham family motto and at the time one of the most expensive wines for sale. The company received a Royal Warrant in 2015.
