Missouri is home to almost 400 vineyards that employ thousands of agricultural workers who pick, crush and nurture grapes like the Norton, the official state grape. Around $60 million worth of Missouri wine is sold each year. Today on Field Notes, we ask an expert to taste a little of that wine. And then we take an inside view ofthe last harvest of the growing season for Les Bourgeois Winery, the third largest winery in the state. From the vineyard, it's on to the winery, where the grapes are destemmed, crushed, fermented and aged.
