Are their industry geared tasting groups in the Sonoma/Napa area?

I was wondering if anyone knows of any industry geared tasting groups in the Sonoma and Marin area? My wife has been working in production for a few years and we have done a lot of tasting at wineries in order to develop her palate and get a basic understanding of the wine made in the region. She is at a point where we think it might make sense to find a tasting group that shares wines and discusses them in order to develop both of our palates a bit. Her ultimate goal is to become a winemaker and after completing her education we both agree this would the next logical step for her is to taste a wider variety of wine with others that have a similar interest.

With all that said, does such a tasting group exist or are there tasting groups in general that might help us out? We are in our mid-late 20s if that has an impact on where we should look to find a group to taste with, though to us age is of no importance; just a serious interest in developing our wine knowledge. If anyone has another suggestion that we aren’t thinking of which would be beneficial we would really appreciate that as well! If there is a wine shop in Sonoma County that does regular tastings that would be great to know about as well. The industry has us on a limited budget so tasting events at fancy restaurants aren’t really in our grasp yet.

Thanks everyone and good luck with the coming season!
