We stopped for a wine tasting. It seemed closed, but you have to ring a bell and someone will appear. We expected to have a sit and drink some wine, maybe bite to eat as well. We have tried two red wines and decided to buy one. It was 6 Euros. My wife told me that a film was made here, ".Good year", with Russell Crowe, Ridley Scott film. The setting was beautiful, but the presentation could be better. I guess that tourists have more enthusiasm so one should take advantage of that. If you offer a glass of wine for 20 Euros on the place where Russell Crowe had his wine, everyone would pay.
However, the lady was sweet, offered us two different wines, they were out of stock for some wine and we bought one bottle cause we didn't have space in the luggage. We just enjoyed it in our room.
I would recommend to the manager a wine tasting package, (4, 5 wines to taste 20, 30 Euros), maybe a cheese, two aside, couple of chairs in front, quick tour at the chateau, some angdote from the movie set, (people love stories, even if they are half true), or something like that. If it wasn't for the movie, no one would know about this place, so try to take advantage of that.
Still the lady was nice to us, charming.
We would spend more than our lousy 6 Euros , but didn't have the chance.
