Previously known as Estremadura, the Lisboa region, located to the west and north of the city of Lisbon, has the most DOC’s of all of Portugal's wine regions. This is a testament to the varied terrain, numerous grape varieties, and historic origin of so many different wine-growing areas.
Many of the wines of Lisboa have pronounced Atlantic influence, and some vineyards – such as those in Colares – are on cliffs just above in the ocean, planted in beach sand. Because of the proximity to the ocean, the grapes are greatly influenced by the sea air. More than 30 different types of grapes grow in Lisboa, and some international varietals are finding their way into the vineyards. Arinto plays a big role in Lisbon whites, as does Fernao Pires. The most commonly used red grapes are Castelão, the famous Ramisco grape from Colares, Touriga Nacional, and Aragonez.
