Oporto Wine, Porto
Once the barrels full of the best vintage of Port wine was floated down river Douro from the vinyards to the companies in Villa Nova de Gaia. Today the are mainly tourist attravctions and show the emblems of the different wineries.
Cross the Dom Luis I bridge and visit the 'caves' (lodges) where the Port wine is stored. You'll be able to visit the cellars and, in the end, taste some Port wine.
The suburb across the river is called Vila Nova. This is where the majority of the port wine production is located, and you can sample and buy these products in many stores lining the river front.
This is one of the most famous wineries for Port wine which is very sweet. The tasting costs 2 euros and you get 4 glasses of wine.
One of Portugal's treasures. You have an oppurtunity to try more Port than you can imagine. Just be careful on the walk back across the Duoro!
Just across the D. Luis bridge, in Gaia, we can find all the port wine cellars.
Most of them can be visited and of course wine tasting is on the program.
You can tour many port cellars. They will guide you through and explain how they make the wine. You can end with a wine tasting. Really interesting and a lot of fun.
