You may recall back in March the Napa Valley Grapegrowers, Winegrowers of Napa County, and Napa Valley Vintners (NVV) submitted a joint letter asking the county to regulate winery development in Napa over concerns about increasing traffic, excessive development and environmental issues [see WSD 03-11-2015 ]. News from Napa this week indicates the discussions happening on the 17-member Agricultural Protection Advisory Committee formed to tackle the issues are not going as the winegrowers had hoped.
