Charles Sturt University’s (CSU) National Wine and Grape Industry Centre director Professor Alain Deloire will address the concept of ‘terroir’ as part of the University’s free public lecture series at CSU in Orange on Friday 27 September. Professor Deloire, previously a team leader in viticulture at world renowned Moet and Chandon, is co-author of a book on “grapevine physiology and terroir” and more than 100 peer-reviewed and popular articles. He said terroir was a complex, but important, notion for agri-food products, but measuring its effect on wine market trends remains difficult even for the experts since it could include climate and soil, people, social organisations and agricultural practices. Despite these complexities, the idea of geographical origin was still critical for products which lay claim to a “terroir-linked typicality”, he said. Head of Campus at CSU in Orange, Professor Heather Robinson, said the Explorations Series of lectures brings speakers from a range of disciplines to share the latest ideas, thinking and opinions on contemporary social, scientific and cultural issues with the NSW Central West community.
