Douro DOC
Summary
This area overlaps with Porto DOC, but is specifically for the production of unfortified wines. Shielded from direct Atlantic Ocean influences by the Serra do Marão ranges, various micro-climates are available due to the winding river that flows throughout the entire area. Produces mainly red blends from the same grapes used in port wines. Blended white wines are also found, made from native grapes often grown as field blends at high altitudes and on granite schist soils.
