A couple of things I noted the past two weeks as I've been out and about:
SAVANNAH-CHANELLE VINEYARDS(408) 741-2930 now has a 100% Pinot Noir tasting option. They've always offered two different tastings but the all Pinot Noir is new. Almost everyone when we were there was doing the Pinot tasting.http://www.testarossa.com/
I spent 30 minutes or so Saturday night talking with the assistant cellar master and the tasting room manager at a party. They both said they have never been busier.
Not great leads for you but they might help. You could also try shannon at scmwa (dot) com She could probably find a few wineries that would be happy to talk with you.
