Colares is a Portuguese wine region centered on the Colares municipality in Estremadura region. The region has Portugal's highest wine classification as a Denominação de Origem Controlada (DOC). Located along the southwestern Atlantic coast, vineyards in the area are protected from the strong ocean winds by sandy dunes. The sand based soils have also had the benefit of keeping the phylloxera louse at bay. The ungrafted Ramisco vines of the Colares region are some of the oldest in Portugal. The region is known for its deep colored, full bodied red wines that are high in astringent tannins.
