Biodynamic Certification
Farmed and made according to biodynamic practices, and certified by Demeter or Biodyvin. Based on the knowledge that the soil, plants, animals and farmers work together in one agricultural cycle. Only a certified organic producer can be considered for Biodynamic certification.
Demeter have rules on growing and vinification is stricter than organic certification - for example, less use of copper sulphate per hectare, and the requirement for natural yeasts for fermentation.
Similar to organic farming, biodynamic farming uses no synthetic fertilizers and pesticides. Biodynamic farming works to achieve soil health through the use of compost, animal and green manures; diversified crop rotations; and incorporation of livestock. However, the two agricultural systems differ in that biodynamic farmers rely on eight specific preparations for the soil, crops and compost to enhance soil and plant quality, and to stimulate the composting process. The eight preparations, designated by their ingredients or by numbers 500 to 507, are made from cow manure; silica; the flowers of yarrow, chamomile, dandelion and valerian; oak bark; and the stinging nettle plant. A ninth prep, often referred to as 508, is made from horsetail and is used for fungal disease.
