Pascaline Lepeltier Presents: A Seminar with Prof. Benoit Marsan "Wine Chemistry for Professionals," Sunday, March 24th, 1:00 - 5:30pm at Racines NY.


Pascaline Lepeltier, Partner/Sommelière at Racines NY  (Meilleure Sommelière de France 2018) will present Professor Benoit Marsan of Montreal who will deliver a seminar entitled "Wine Chemistry For Proessionals" on Sunday, March 24 at Racines NY.  Professor Marsan holds a Ph.D. in Chemistry and has been a professor at the University of Quebec at Montreal (UQAM) for more than 30 years. A speaker at national/international conferences, symposia and wine shows, he teaches wine chemistry to wine professionals and consumers. In November 2018, Professor Marsan delivered a master class on the perception of minerality in wines as part of the Boot Camp SOMM360 activities attended by 22 of the best sommeliers of the world. “I met Benoit in Montreal. We had a fantastic conversation about the concept of minerality and how misunderstood it was. It was so stimulating that I asked him to come to New York to lead a longer talk on the subject. We will taste ten wines in correlation with different wine chemistry topics that the Professor will touch on.” Pascaline Lepeltier, MS.
