How does one make wine from grapes? Following the rhythm of the four seasons of a wine growers year, the film shows us the work, the worries and the joys of a family of wine growers and producers, the Potterats of Lavaux, Switzerland. Three generations who live and work together, keeping up old-time traditions. Techniques may have changed and know-how may have improved, but the pitched region of Lavaux has seen relatively little mechanization due to the small size of the holdings. The love of a job well done is what sets these «gardeners of the vine» apart, with their delight in healthy grapes and the need to see and touch what they produce.
