Clos Du Bois seemed to make a very little effort to hide the corporate image with big buildings and parking lots marked 'Corporate visitors only'. Still they make a very decent selection of table wines, especially at their pricing. Have you been to Costco lately? While I have yet to purchase a bottle of Clos Du Bois it has been served to me a number of times visiting friends. My goal is to make a trip to try their higher end wines and their flagship "Marlestone" and their old vine carignane.
