Porto Augusto's, Vila Nova de Gaia

If you want to support local, family-owned, small and independent business (rather than the big, foreign-owned ones), make sure to visit this Porto maker. Because of their size, they do not compete with the big brands on the first line of the river boulvar - but, man, it's so worth to step into a narrow alley for a visit in their shop. They offer a small tour, very informative, followed by a nicely structured tasting. And the porto is just exquisite. Also, you can buy their port only in their shop, not in shops or the airport - make sure to use this opportunity, also for travel-sized packages.

The English tour was very informative and the port was exquisite. Well worth the money, which is also partially refunded if you buy a bottle of their port. We ended up buying 4 bottles as we enjoyed it so much. Feels great to support a small family business.
