Port is a fortified wine from the remote vineyards in Portugal's Douro Valley. Here, in the Douro Valley, time has almost stood still. You will not find the latest wine making techniques and fancy equipment. Instead, you will find a wine industry much the way it was over a hundred years ago. Yet, in spite of it, or because of it, vintage Port is one of the world's greatest wines. Port takes its name from the city of Oporto that is situated at the mouth of the 560-mile long Rio Douro or River of Gold. Although many port-style wines are made around the world – most notably Australia, South Africa and the United States – the strict usage of the terms Port or Porto refer only to wines produced in Portugal. It is these wines that we will explore here.
