Alentejo (Vinho do Alentejo, Alentejo wines) is a Portuguese wine region from the Alentejo region. The entire region is entitled to use the Vinho Regional designation Alentejano VR, while some areas are also classified at the higher Denominação de Origem Controlada (DOC) level under the designation Alentejo DOC.[1][2] VR is similar to the Frenchvin de pays and DOC to the French AOC. In the southern half of Portugal, the Alentejo region covers about a third of the country and is sparsely populated. In 2005, South Oregon University scientist Gregory V. Jones identified Alentejo ("southern Portugal" in his words) as the world's most challenged wine region (out of 27 world wine regions) from a climate change perspective. The region is noted for it vast cork production but has in recent years garnered attention for its table wine production.[3] Some producers of this region still make wine in great pottery vessels, as in Roman times.[4]
