In this episode vineyardist, David Bos, brings a lot of enthusiasm for organic and biodynamic farming.  David learned farming on the ground while working for Grgich Hills Estate in the Napa Valley, which is known for their commitment to natural winegrowing and sustainability.
These days David runs his own small farming Company, Harvest Bos, and is known as a specialist vineyard consultant for those who have an interest in employing organic and biodynamic farming.  That said, David doesn't smell like patchouli, doesn't speak in flowery prose, and doesn't believe we should get sidetracked by the less practical aspects of biodynamics.
 
In great detail he explains "that biodynamics can give you better health, quality, vitality" and the four tenets that he deems critical towards that end are compost, observation, biodiversity, and the biodynamic preparations.  The bulk of our conversation is spent exploring those topics and how David incorporates them into the care of his vineyards.
