Taylor's Cellars.

The tour is very informative and you will discover the many different varieties and the history of this world famous wine. You will need to climb the narrow lanes but this is well worth the effort as you will get to a splendid view of Porto and its estuary. Having had a tasting of 3 different wines you will be hungry by now, so reward yourself with an excellent meal in the restaurant "Barao de Fladgate" before burning off the calories with a digestive stroll along the banks of Gaia.
