In July 2006, the Pew Initiative on Food and Biotechnology and the American Vineyard Foundation held a workshop in San Francisco, CA examining issues relating to the potential adoption of biotechnology in the winegrape and wine industries. Over the course of the two-day event, grape growers, winemakers, grape and yeast research scientists, federal and state government representatives and agricultural commodity and specialty crop producers gathered to discuss the scientific, regulatory and marketing issues associated with the potential development of genetically engineered (GE) winegrapes.
