(AP) — When Dominic Symington looks out from his shady hillside garden across the vineyards of Portugal's majestic Douro Valley, he sees centuries of family and European history. British families like the Symingtons have been at the heart of this northern Portuguese region's port wine trade for generations. Dominic Symington, one of seven in the family wine business, has an ancestor — Walter Maynard — who shipped port to Britain in 1652. Port, Symington says in an impeccable British accent, is a "way of life" for his family and tens of thousands of farmers along the River Douro.
