I guess a few large wineries were built outside of town (freixenet is one of them) and now Queratoro is developing a wine and cheese tourism industry. For about $100 bux you can have someone drive you around in a private car all day and you can pop in and pop out pretty quickly.
The wine is young and boring but there’s a lot of scenery to appreciate and decent cheese for basically free.
Every other time I went I got sick from eating local food. I don’t have any restaurant recommendations.
