Sogrape
The Sogrape Vinhos S.A. is a Portuguese winery founded in 1942 by Fernando van Zeller Guedes as “Sociedade Comercial dos Grandes Vinhos de Mesa de Portugal”. It is the largest family-owned wine company in Portugal.
Its first product was the rosé wine Mateus. It continued to produce quality wines with the style of a small family winery while modernizing and expanding through acquisitions to diversify into other areas of the Portuguese wine industry. By the end of the 1980s Sogrape became the largest wine producer in Portugal.
Sogrape owns the port wine brands Ferreira, Sandeman and Offley.
