We were a group of 4 and had booked a tour here through our hotel (after checking reviews). This was one of the best tasting/tour experiences we have had in Europe or the US. Our host was Sophia who was excellent. While she was a little under the weather, Sophia was charming, well informed and knowlegeable. After a short walk out to a vineyard, we procedded to tour their production facilities and then settled in for a delightful tasting and light snack. The wines are very good and we purchased several bottles to enjoy. Highly recommend a stop here and request Sophia if you can. She was even gracious enough to recommend and book a dinner reservation for us near our hotel in Penafiel.
