Port wine
Douro DOC, which is famous as the Port wine region, is also located in Trás-os-Montes e Alto Douro and could use the former Trás-os-Montes VR designation. However, with the creation of a separate Duriense VR, Douro vineyards are now separate from both the Trás-os-Montes DOC and Transmontano VR.
