In this episode, Jono chats to Johan Reyneke; owner of Reyneke Wines, and pioneer in biodynamic viticulture in South Africa.   The episode is primarily concerned with the fascinating world of bio-solutions in viticulture, but as so often happens when Johan is involved, the topics spread both broader and deeper; touching on the philosophy of science, the economics of animals in viticulture, and the need to restore a holistic view of farming.
