This is by far one of my favorite cities to visit and was so lucky to have been able to call it home before we made the decision to move to the Bordeaux region. These are my suggestions for your visit in Barcelona.
This region is famous for wine production, so when Charles DELALAND opened up his Brasserie Distillerie Cabestan he wasn't very worried about the competition or fitting in with the local vinters in Saint-Croix-du-Mont. The brewery is tucked into the center of town, almost hidden behind a tall gate that from behind looks out over the Garonne valley and onto the vineyards of Sauternes in the distance. It's an incredibly scenic and inviting atmosphere for summer evenings.
