Following five family wineries, an amateur home winemaker and all-female picking crew, 'Harvest' documents the 2011 wine-grape harvest in Northern California, revealing 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 the back-breaking manual labor and night picks at 2 a.m. with only headlamps. Along the way we meet the first migrant worker to own his own winery and the women pickers share their border-crossing stories. It all leads up to untimely October rains that wreak havoc and create what many old-timers call 'the worst harvest' in their lifetimes. 'Harvest' is a rare, intimate glimpse of the vineyards that has never before been captured on film.
