I'll be in the Douro next weekend (driving in from Porto on Saturday (morning) and leaving monday). We'll be staying at Quinta de la Rosa (sat) and Quinta do Tedo (sun).
Any advice on other quinta's to visit? I would love a good in-depth vertical tasting. Of course, I don't mind getting my hands dirty an lending a hand somewhere isn't an issue. But I am bringing a significant other, so I am on a (albeit long) leash and can't commit to a full day of work

As a huge Niepoort advocate (and fan) I would love to visit Quinta de Napoles and see the facilities there. As far as I understand, that's prior arrangement only? Any other good advice is always welcome.. Dining options, other activities, etc. And I know that Roy's harvest tour is there this week, so we might run into each other!
Thanks!
Roel.
