The biodynamic farming is a continuation of the organic farming, but its specifications are more restrictive than those of the organic farming. To be certified in biodynamic cultivation, the vineyard must be first certified "Organic Farming". It musts then meet the requirements of the biodynamic specifications with the spraying of various herbal preparations to fight against pests and promote the good vines development, and in the respect of the lunar and astral cycles defined in a schedule established at this effect.
In winemaking, the biodynamic vinification prohibits the majority of the oenological inputs tolerated in organic farming, and the permitted sulphite levels are even lower than those set in the organic specifications. Several labels certify the biodynamic viticulture, of which the best known are DEMETER and BIODYVIN.
