Since 1927, Demeter has been the trademark for products from certified biodynamic production, a method of organic farming originally developed by Austrian philosopher Rudolf Steiner. He introduced the idea of a holistic farming system based around the phases of the moon, composting and mixing crops with livestock.

Key features of Demeter farming: The avoidance of synthetic fertilisers – The use of manures and composts – Frequent crop rotations – Avoidance of chemical soil treatments – Measures to strengthen the life processes in the soil – Consideration of celestial and terrestrial influence.
