Less than an hour from Barcelona’s city center, Sant Sadurní d’Anoia is the perfect day trip for wine aficionados, particularly fans of cava, the sparkling wine from Catalonia. Tour the grounds at multinational operations like Cordoníu and Freixenet, or sign up for a tasting at one of the smaller mom-and-pop operations. Most wineries have bottles for sale and larger operations can even ship a case home for you. Bus and bike tours are available.
