Celler Joan d'Anguera
This is a very good wine producer from DO Montsant. Fortunately I had chance to visit the cellar in Darmós. It is a nice experience, and you will find better prices than in normal shops: a whole box (6 bottles)of finca l'Argatà for 75 eur. A whole box (6 bottles) of Planella for 50 eur.
They have a nice wine-tasting room and offer wine tastings for 70 eur per group (up to 10 people per group). If you do not buy the wine-tasting, the visit is free of charge and includes a cup of finca l'Argatà. Worth to visit.
