Cava Codorniu is the oldest cava producer in Spain, and one of the biggest sellers too. Located in the town of Sant Sadurni just a few minutes outside Barcelona, it is very well known for its modernist architecture and sprawling grounds.

How to get there: As I mentioned in my earlier post, you can take the train and then stroll over or take a cab to the winery. Codorniu also has a bus service from Barcelona, that picks up at a couple of stops and bring you to the winery – a good option for larger groups, or if the train is too much hassle.
