Michael Donohue, M.A., WSET-Certified, Bordeaux Wine Council

Michael Donohue was born into a family of occasional beer, rye and Manischewitz drinkers but was really  bitten by the wine bug in university, when different red Côtes-du-Rhône prompted an ongoing investigation of why one could taste so much better than another. 

Following graduation with a Master of Arts in Philosophy, Michael worked in retail operations and then in high-tech (from 300 bps to ATM) all the while taking various wine courses, including the WSET Diploma*, and travelling to many of the world’s great vineyards. Michael has been teaching WSET courses for about 18 years and for the past decade was a Director of the Independent Wine Education Guild www.iweg.org, a WSET affiliate since 1977.  After getting whacked in the dot bomb era, he finally listened to those career consultants who say you should do what you love and the money will follow.

Before joining GalanteVineyards,  a youngish winery with huge accomplishments and a rich future, Michael co-founded Ne Plus Ultra Agencies, which represents >50 international wine and spirit producers and worked for two other companies with Chateaux Pétrus & Palmer, Grey Goose, Chave, Shafer, Caymus & Avignonese (amongst others) in their portfolio.
