Not far from Vilanova (around 25kms) is Sant Sadurni d'Anoia where many of the most well known houses of Cava are located.
One you are bound to have heard of is Freixenet.
Currently traveling there is not allowed, as it is not in our comarca of Garraf which is a shame a they are offering special combined tours of visits to the cellars plus another, at great prices...
You can also get a combined travel by train ( from Barcelona) and tour, which at €16.50 is a great price too.
For more information about these offers and Freixenet in general go to www.freixenet.es/en
Where you can find in Spanish, Catalan and English
