Biodynamic farming is limited in its application here in Paso Robles, with some people claiming adherence while very few acres are actually certified Demeter. It costs around 20% more to farm than standard viticulture, mostly due to higher labor inputs and the outlawing of weed control chemicals. The additional risks of unmanageable pest infestations and fewer vine nutrition amendment options also create a more variable yield, making annual income forecasts difficult. Pest control practices allowed under Certification include the burning and spreading of pest's ashes to ward off further infestation and spraying homeopathic solutions to balance the energy of the vineyard at specific times. Currently there are no established grape or wine premiums for organic or biodynamic vineyards, but these farming 'labels' can provide unique value propositions to select wineries and consumers. Given the higher cost and potential lower return on this style of farming, its typical application is by winery estates who can use the 'story of the farming' to hand-sell product.
