Benoît Marsan holds a Ph.D. in Chemistry from Institut national de la recherche scientifique (INRS). He is a professor at the University of Quebec at Montreal (UQAM) since more than 30 years and is internationally recognized in the field of solar energy whose innovations have been listed among the Top 10 discoveries of 2010 by Quebec Science magazine. Being a great wine passionate, he was educated in professional tasting by Bertrand Eichel, the best sommelier of Quebec 2009. He was twice a member of the winning team of Amicale des sommeliers du Québec tasting competition (2013-2014). Having refined his knowledge and expanded his expertise in wine chemistry, he founded scienceetvin.com in 2015. Speaker at national/international conferences, symposia, and wine shows, he teaches wine chemistry to wine professionals and the general population. From 2013 to 2016, he has been an important contributor to the course Analyse sensorielle et analyse organoleptique at Institut de tourisme et d’hôtellerie du Québec (ITHQ). His numerous discussions with winemakers and oenologists worldwide, including during Congrès national des OEnologues de France, together with private sessions with some of the best sommeliers of the world, have strengthened his conviction to create a course at UQAM dedicated to wine chemistry. This very popular course, entitled Science et vin : de la vigne à la dégustation, has greatly contributed to the Teaching Excellence Award he received in 2017 from the Faculty of Science at UQAM. In 2017, he created an innovative 2 part wine chemistry course (total of 48 hours) specifically for sommeliers: Chimie et sommellerie, Volet 1 : Pour mieux comprendre le vin, and Chimie et sommellerie, Volet 2 : Pour mieux déguster le vin. In November 2017, he contributed as a wine scientific expert to a workshop held at ITHQ on the perception of minerality attended by 50 top sommeliers.
