Alain Deloire obtained his PhD in 1982 from the University of Montpellier II (France) and a Doctor of Science (DSc) in 1998 from the University of Montpellier I. He spent ten years as a researcher and team leader in viticulture at Moët & Chandon in Champagne, France.

He later served for 14 years as Professor of grapevine and fruit ecophysiology at Montpellier SupAgro, co-authoring three books on Grapevine Physiology and Terroir, and is the author or co-author of more than 300 scientific and technical publications. His research focuses on grapevine physiology and grape berry development and biochemistry.

He was Professor of Viticulture at Stellenbosch University from 2009 to 2012, Head of Department from 2011 to 2012, and Extraordinary Professor from 2013 to 2015. From 2013 to 2016, he was Director of the National Wine and Grape Industry Centre at Charles Sturt University (Australia).

Gabriel Lepousez

Neuroscientist – Research Scientist, Perception and Memory Laboratory, Institut Pasteur (Paris)

Gabriel Lepousez is a neuroscientist specializing in the perception and processing of odors and flavors. His research focuses on how the brain perceives, memorizes, and interprets information from the environment, notably the mechanisms underlying certain mental disorders. His work is particularly centered on the learning of flavors, the principles of individual variability, and the role of memory in sensory experience and taste-related behavior.

Passionate about tasting and oenology, Gabriel combines a deep scientific understanding of sensory perception with a keen interest in the world of wine and gastronomy. He is the author of numerous scientific articles and has spoken on several occasions about the sensory and neurological dimensions of wine and tasting.

Among his distinctions, Gabriel Lepousez is a member of the Jury du Vin de France and the OIV (International Organisation of Vine and Wine), Master of Sensory Analysis, Master of Wine Management, and a certified taster. He is also a member of the Comité de Dégustation de la Revue du Vin de France, a member of the Académie du Vin de France, the Académie Amorim, the Association Francs de Pied, and the tasting panel of the Union des Œnologues de France.

Jacky Rigaux

Researcher and Author – Specialist in viticultural terroirs and geo-sensory tasting, University of Burgundy (retired)

Jacky Rigaux holds a doctorate in Psychology (University Paris-7, 1987) and is a former research engineer at the University of Burgundy, where he created two original degree programmes: 'Wine and Culture' and 'The Practice of Tasting through Knowledge of Terroirs'. His research focuses on the relationship between terroir and tasting, approached from historical and epistemological perspectives.

Author of numerous reference works on Burgundy wines and viticultural terroirs – translated into English, Japanese, Czech and German – he is the pioneer of geo-sensory tasting, a method developed with Henri Jayer and whose neuroscientific foundations have been validated by Gabriel Lepousez. He served as a member of the Scientific Council for the UNESCO World Heritage listing of the 'Climats' of the Burgundy wine region. An international lecturer, he organises the annual Henri Jayer International Encounters at the Château de Gilly-lès-Cîteaux.
