Lisboa is a historic wine region (formerly Estremadura) located northwest of the capital city Lisbon and stretching out in an area of about 40 km alongside the Atlantic coast of Portugal. The region's climate is relatively mild because of the proximity to the Atlantic, which has a great impact on it. The summers are fresh and winters soft making the ripening season prolonged. Around 20 years ago the region has been related to producing large quantities of low-quality wines, but today that has changed like the name of the region, and some major renovations have taken place in the vineyards and the wineries. The region is priced for its diversity of grape varieties and different styles of wines with the most frequently used grapes Arinto, Fernão Pires, Trincadeira, Touriga Franca and Touriga Nacional, as well as the international Cabernet Sauvignon and Merlot. Lisboa wine region is divided into nine sub-areas or DO (Denominations of Origin) including Colares, Carcavelos and Bucelas in the south, near Lisbon, Alenquer, Arruda, Lourinhã, Torres Vedras, and Óbidos in the heart of the region and Encostas d’Aire in the north, close to the Beiras region. Each one of them has its unique terroir and leading grape varieties as the most renowned wines are coming from Alenquer for the red wines, and Bucelas for the whites. Overall the region has big potential which hopefully will be fulfilled.
