In the last decades the world has seen some acceleration in the process of internationalization, affecting virtually all industries. The wine sector is no exception, witnessing increased exports and imports and a movement of mergers and acquisitions. Among European wines, Port Wine can be seen as a representative case of integration in international markets, with about 90% of its production to be exported. After the World War II, although the Port Wine activity has been subjected to cycles there has been a trend towards a continued increase in production and exports, stabilization of real market prices and a slight increase in the real prices paid to grape growers, leading to positive economic effects for Port Wine firms and grape growers.
