A Taste of Northern Portugal is our fourth wine tour with Shannon and each tour seems to get better. This one was a nice balance between the vinho verde, just south of Galicia in Spain, and the great Port district along the Douro River. We visited very historic sites, had many memorable, delicious meals and visited and tasted at a remarkable variety of wineries ranging from small producers of white wines to the noted, theatric presentation at Sandeman, one of the major Port producers. it would be difficult to imagine a better experience.
