Harvest time means something else entirely for our good buds in counties north, but in Sonoma and Napa, it’s grape-stompin’ time. At this week’s Harvest Fair, attendees can roll up their blue jeans, throw off their boots and stain their calves purple in the World Champion Grape Stomp. Sonoma County’s food and wine culture flourishes with port and chocolate pairings, tasting pavilions, wine judging, biodynamic garden tours, chef demonstrations, cooking competitions and wine, wine, wine. Get juicy on Friday—Sunday, Oct. 4—6, at the Sonoma County Fairgrounds. 1350 Bennett Valley Road, Santa Rosa. Oct. 4 at 4:30pm; Oct. 5—6, noon. $50—$90. 707.545.4200.
