Douro DOC

Overview

The Douro Valley is Portugal’s most dramatic wine landscape—a UNESCO World Heritage Site where terraced vineyards climb impossibly steep schist hillsides above the Douro River. While the region has made Port for over three centuries, the Douro DOC for unfortified wines has emerged as one of Portugal’s most exciting quality wine appellations. The same grape varieties, ancient terraces, and extreme terroir that make great Port also produce powerful, complex red wines and increasingly impressive whites. For enologists, the Douro offers essential study in extreme-terrain viticulture, Portuguese indigenous variety expression, and the transformation of a fortified wine region into a still wine leader.
