Portugal is a country with a rich wine-making tradition and a diverse range of wine styles. The country's wine regions are spread throughout the country, from the cool, rainy Atlantic coast to the hot, dry interior.

The most famous wine region in Portugal is the Douro Valley, which is located in the northern part of the country. This region is known for producing some of the world's finest fortified wines, including Port. The vineyards in the Douro Valley are planted on steep, terraced hillsides overlooking the Douro River, and the grapes are grown in a hot, dry climate.

Another important wine region in Portugal is the Alentejo, which is located in the southern part of the country. This region is known for its full-bodied red wines, which are made from local grape varieties such as Aragonez, Trincadeira, and Alicante Bouschet. The climate in the Alentejo is hot and dry, which helps to produce wines with intense flavors and high alcohol content.

Other notable wine regions in Portugal include the Dão, Madeira & Pico Islands, and Vinho Verde regions. The Dão region, located in the central part of the country, is known for producing elegant, well-balanced red wines made from the Touriga Nacional grape variety. The Bairrada region, located near the coast, is known for its sparkling wines, as well as its full-bodied red wines made from the Baga grape variety. The Vinho Verde region, located in the northwest of the country, is known for producing light, refreshing white wines with a slight spritz.
