The California wine industry is under siege. A global wine glut, younger generations turning away from alcohol, and a contentious battle over the future of Napa County wineries have left the enemy inside the gates.

Stu Smith, proprietor of Smith-Madrone Winery in St. Helena and a longtime small winery activist, joined us to tell the story.
