A documentary about the world's greatest wine celebration in the most legendary of wine regions during its most difficult season: Three Days of Glory offers a glimpse into aspects of Burgundy never filmed before. Burgundy is home to the most legendary wines on the planet. But it wasn't always that way. A series of difficult years in the 20s and 30s led to the creation of the events now known as Les Trois Glorieuses, or the Three Days of Glory. This is the story of that festival, its origins, and the small-estate winemakers of today who have faced a string of brutal years that threatens their very survival.
