Part 6/9:
One of Porto's most famous exports is its port wine, and Ian and Anna make a day trip to the stunning Douro Valley, the heart of port wine production. At the first vineyard, they learn that the sweet, fortified wine holds a unique place in both local and international wine culture. The process involves adding brandy during fermentation to preserve the wine for long sea voyages, a tradition that dates back centuries.
Among the highlights of their tour is a boat ride along the Douro River, where they savor local refreshments while taking in the picturesque sights of terraced vineyards. As they explore the region's history and winemaking techniques, they taste several varieties of port wine, deepening their appreciation for this integral part of the Porto experience.
