My review, although it shows as a solo, it's a mix of several visits I made already there. I am a member of their club.
As a local, I decided to go to a wine tasting at Suisun Valley with a friend of mine with my wife being our "designated driver". As owner of a small limousine company, I brought several clients to the wineries in Suisun Valley but never had the opportunity to try them myself. And I was glad to know that, although they are not "fancy" or they are not "boutique" wineries like in Napa or Sonoma, the quality of most part of the produced wines is very good.
I was specially impressed with Wooden Valley winery. The quality of their wines is at the same level or even better, in some cases, than the wines in Napa. I suggest the Merlot and the Riesling varieties. They are my favorite. They have two types for Riesling actually. And for those who prefer more dessert wines, I suggest White Gamay or Miscela.
The hosting needs some improving yet but it's much better since I went there for the first time on 2012.
And their prices are chiper than the ones in Napa. You won't regret.
