Port Wine Cellars, Vila Nova de Gaia

Vila Nova de Gaia, directly across the Douro from Porto's Ribeira, is home to the historic port wine lodges where houses such as Graham's, Sandeman, Calém, Ferreira and Taylor's age their wines in barrel cellars carved into the riverbank hillside. Visitors join a guided lodge tour to walk among rows of oak barrels, learn about the fortification and aging process behind ruby, tawny and vintage ports, and finish with a tasting of two or three styles. Many lodges also have terraces or rooftop bars overlooking the river and the Ribeira skyline, and several display retired rabelo boats once used to ship barrels downriver before road and rail transport took over. A single lodge visit runs one to two hours including the tasting, and the compact layout of the district makes it easy to combine two or three lodges in a single afternoon by walking between them along Avenida Diogo Leite. Weekday mornings offer noticeably smaller tour groups, while summer weekend afternoons see queues at the most popular houses and often require booking ahead. The lodges themselves sit right at the base of Ponte de Luís I, so the walk over from Ribeira takes only a few minutes, and many visitors pair a lodge tour with a rabelo boat ride on the river before or after tasting.
