The region has Portugal's highest wine classification as a Denominaxc3xa7xc3xa3o de Origem Controlada (DOC).
Alto Douro was one of the 13 regions of continental Portugal identified by geographer Amorim Girxc3xa3o, in a study published between 1927 and 1930.
The Methuen Treaty between Portugal and England in 1703, and the subsequent establishment of many British Port lodges in Porto meant that Port wine became the primary product of the region, and it became economically very important to Portugal.
A contributing factor was Portugal's entry into the European Economic Community in 1986, which meant that the Port lodges' monopoly was abolished,[4] thus paving the way for producers in the Douro valley to produce and bottle their own wine - Port or dry Douro wines.
The Douro equally belongs to the small shopkeepers and middlemen in the region, to the owners of the quintas xe2x80x93 both Portuguese and foreign xe2x80x93 who stay there at different times in the year, to the shippers in the Douro and in Vila Nova de Gaia who are engaged in the wine trade, and to all those people in Portugal and the world over who have learnt to celebrate each great moment in their lives or in the destiny of nations with a glass of Port wine.
