Valley of the Moon Vintage Festival returns to Sonoma this weekend

The month of September is California Wine Month, and harvest is one of the best times of year to get out to wine country. So, a little piece of the harvest came to our KTVU studios. Robyn Sebastiani, the executive director of the Sonoma Valley Vintners & Growers Alliance, joined Roberta Gonzales on "The Nine" with a grape stomp to preview the Valley of the Moon Vintage Wine Festival in Sonoma this weekend.
