We'll be in the area for about 5 days in late June. The number of wineries and options seem overwhelming. Are there any wineries that are recommended for reasonable (under $30) dry reds, especially the cab francs and sauvignons, interesting blends, and perhaps some nice zins and rieslings? If there are some good whites to be found there too, that's a plus, but we're primarily interested in reds. An informal atmosphere, and perhaps a restaurant and/or exceptional grounds and view would work very well, too.
