Jean-Marc is a worldly winelover who marries respect for terroir with contemporary open-mindedness. He spent time making fizz in Australia and the U.S. for Chandon at the start of his Pierry quest. Jacquesson, across the way in Dizy, has since been an indelible influence. Like their CellarHand stablemates the Chiquet brothers, every step chez Jean-Marc and Oriane has been chosen at the expense of myriad alternatives rejected because they’ve been shown to yield something less than the best wine possible.
