Biodynamic viticulture is just a step up from organic whereby they make their own pesticides from natural and sustainable ingredients like tea or cow manure. This is teamed up with ensuring biodiversity within cover crops and having animals to help them tend to the weeds (as well as giving some fresh manure). Then comes the lunar calendar and the interplay that has with the soil and plants. Biodynamic growers are truly at one with their land and their vines and produce some of the finest fruit in the world. This is best teamed up with a natural winemaking philosophy to ensure a pure wine as a result.
