Shot entirely on location in Sonoma County, the documentary film, Harvest, will be screened at 11 a.m., April 19, at The Loft Cinema. It reveals the blood, sweat and tears that go into every bottle of wine. There is no swirling, no sniffing, no sipping or quaffing. This is all about back-breaking manual labor and night picks at 2 a.m. with only tiny headlamps for illumination.

Over the course of three months during the harvest of 2011, the film follows five family wineries: Robledo, Rafanelli, Foppiano, Harvest Moon and Robert Hunter, along with an amateur home winemaker and an extremely rare allfemale picking crew from Mexico. They are plagued by destructive rainstorms and widespread grape rot.

Director John Beck casts his lens on salt-of-the-earth, tight-knight family farmers and field workers that are the backbone of the wine industry. Harvest offers a rare, intimate glimpse into the making of the wine we drink that has never before been captured on film.

General admission $6/$5 members. Location: 3233 E. Speedway Blvd. For more information, call 520-322-5638 or visit LoftCinema.org.
