Biodynamic Viticulture

Biodynamic viticulture goes beyond organic farming. While organic viticulture eliminates synthetic pesticides, herbicides, and fertilisers, biodynamic farming adds a holistic philosophical framework derived from Rudolf Steiner's lectures on agriculture (1924). The vineyard is treated as a living organism connected to cosmic rhythms.

Practical biodynamic practices include: applying specific herbal and mineral preparations (numbered 500–508) to the soil and plants; timing vineyard work (pruning, harvesting, racking) according to a lunar and astronomical calendar that classifies days as "root days," "flower days," "fruit days," and "leaf days"; and building soil biodiversity through composting and cover crops.

Proponents argue that biodynamic farming produces healthier soils, more expressive terroir, and ultimately more complex wines. Sceptics question the scientific basis for the lunar calendar. However, the requirement for careful observation and intervention timing does tend to produce very attentive viticulture regardless of the philosophical underpinning.

Premier biodynamic producers include Domaine Leroy and Domaine de la Romanée-Conti in Burgundy, Nicolas Joly in the Loire, and Zind-Humbrecht in Alsace.
