We explore wine destinations around the world. First we head to the picturesque village of Epesses in the Lavaux winegrowing region of Switzerland, home to the largest vineyard area in the country and a Unesco World Heritage Site, to meet Blaise Duboux and tour his eponymous estate. We also meet the founder of an agency working to build up and promote wine tourism in South Africa. See omnystudio.com/listener for privacy information.
