Reference book from Nicolas Joly, a famous winemaker from Coulée de Serrant, a pioneer of biodynamics, to discover and learn about biodynamics. In order to better understand the issues and principles of this method of cultivation in harmony with nature, Nicolas Joly begins by tracing the history of the damage caused by modern agriculture to the vines. In the context of the industrialization of processes and agricultural techniques, biodynamics is above all a return to natural winemaking, to a respect for the vine and the environment in order to achieve the best expression of the terroir possible. This book covers all aspects of biodynamics: understanding the forms and their correspondences, using the forces of the living, making use of astrological cycles, etc.
