Also known as Biodynamic viticulture, this is a production method for making grapes and wine (principles and general information are described under Organic Viticulture, the study of which is also recommended as an introduction to this complex subject). It goes back to the Austrian anthroposophist Rudolf Steiner (1861-1925). He studied mathematics, natural sciences, philosophy, literature and history in Vienna. In the 1920s, Steiner established rules for "biodynamic agriculture" for the prosperity of agriculture and propagated them through numerous lectures. The core statement of his philosophy is that the illness of a plant is the sign of a naturally disturbed equilibrium and is due to the use of chemical aids in fertilization. At first, biodynamics developed in agriculture and horticulture, viticulture was added later.
