The ancient city of Porto, capital of Portugal, has a wine history which stretches back over the millennia, and helped shape the world of wines as we know it today. Sailors and explorers leaving Porto helped introduce grapevines to the New World in the 16th century, and thanks to the vast variety of vines which grow around Porto, they had plenty of varietals to choose from. Indeed, over a hundred grape varietals are permitted by law for use in Porto's famous Port wines, although only five are commonly grown and processed in the impressive and historic Port wineries. The Douro river valley which Porto's finest vineyards are situated in is in fact one of the oldest protected wine regions in the world, and thanks to its mineral rich soils and wonderful climate, is widely regarded as one of the world's most ideal locations for viticulture.
One of the oldest regions of Portugal for wine production and vine cultivation is the Bairrada, the lush and clay-rich region responsible for an impressive range of red, white and rosÃ© wines of exceptional quality. As with much of the country, this region benefits from long, hot summers, allowing the grapes to ripen to full maturity and thus carry a wide range of flavors and aromas. However, each region of Portugal produces wines which reach a high level of quality, from the more urbanized regions around Lisbon and Porto, where the famous fortified and Colares wines originate, to the island of Madeira and the Dao river valley, which each have their own distinctive wine cultures. The several thousand years of viticultural history in Portugal has allowed Portuguese wineries to master their own traditional techniques, which are still employed to this day across the country, yielding excellent results for the world to enjoy.
