Andreia brings a wonderful depth of historic and local, personal knowledge to the tour. They and their families worked the vineyards. She, and her wonderful husband driver, are so kind and caring. We had a lovely visit to a small local winery where they still crush grapes by foot in concert containers. We stopped at beautiful locations to allow us to take photos and enjoy the scenery; the roads are so curvey these breaks are appreciated. I really enjoyed the local restaurant in the small, non-touristy village. Our highlight was the port stop with its wonderful wine host; he made our day by his enthusiasm and kindness.
