Pick up a group Sitges go to Penedes for a Cava Tour with a guide

Greetings All,
We're looking for a Cava Tour for a group of eight. Staying in Sitges, Spain.
We would like to go to the Penedes area to visit Cava & Wineries.
Pick us up and return the group to Sitges.
Any suggestions?

Cheers,

Bruce
