Katie Madigan discusses her journey from chemistry to winemaking and the importance of sustainability in producing quality wines at scale.

This week, a behind-the-scenes look at how great Sonoma wine actually gets made. Katie Madigan of St. Francis Winery shares how she went from chemistry student to winemaker, why sustainability is more than farming, and how to keep soul and quality in wines priced around $15–$18.
