The wine region of the "Vinho Verde" (Green Wines) is the largest in Portugal, with its 34000 hectares spread along a coast area geographically well situated, rich in water resources, with mild temperatures and abundant rains, which created homogeneous and mainly granitic soils, fertile and with high acidity, excellent for the production of white wines.

The brand image of this region is the variety Alvarinho. Natural issues, microclimates, wine types, vine varieties and ways to cultivate them, led to the division of the Demarcated Region of the Green Wine in nine sub-regions: Amarante, Ave, Baião, Basto, Cávado, Lima, Monção e Melgaço, Paiva and Sousa.

The dominant white varieties are Alvarinho, Arinto (Pedernã), Azal, Loureiro, Avesso and Trajadura, while in the red varieties the dominant are Borraçal, Espadeiro, Brancelho e Vinhão. Since 1999 the region produces sparkling wines of great quality and shows itself as one of the most promising places for the production of top sparkling wines.
