Forget about swirling, sniffing, and sipping, “Harvest” takes a look at the back-breaking manual labor and 2 a.m. night pickings of harvesting grapes and making wine. “Harvest” follows five family wineries in Sonoma County, Calif., during the 2011 harvest, which turned out to be the worst in that region in 50 years. The feature-length documentary is the next film in Suwanee’s Southern Circuit Tour of Independent Filmmakers and will be shown at 7 p.m. Tuesday, Nov. 12, at Movie Tavern.
