This film takes us to the heart of the very closed universe of Saint-Emilion´s greatest wines, among the most highly respected in the world. As is done every ten years, Saint-Emilion´s grand cru wines are going to be reassessed. The tension is already mounting and tongues are wagging, since the reassessment can have a deep economic impact. We take a behind-the-scenes look at the event through highly colorful portraits of four vineyard owners, all of them passionate about and in love with wine. The ups-and-downs of one of the most sought-after wine lands in the world. Reality cinema in a very strictly controlled environment!
