The Lima River runs through the Vinhos Verdes municipalities of Arcos de Valdevez, Ponte da Barca, Porte de Lima and Viana do Castelo, where it meets the Atlantic Ocean.
This is a wide valley, with no shield against the Atlantic winds, which freely penetrate this subregion. Rainfall is frequent and the mild climate is relatively cool and humid during ripening season.
In other words, Lima has everything that the Loureiro grape likes, so it's no surprise that this is this grape's subregion of choice. Indeed, the area is renowned above all for its fragrant, elegant and long-lived Loureiro grape, yet the subregion also produces crisp, citrusy whites from Arinto and Trajadura grapes.
The subregion's reds, Vinhão and Borraçal, are generally grown further inland.
