Jean-Baptiste Lecaillon grew up in Reims surrounded by the world of Champagne. At a very young age, he developed a passion for Champagne and its development. He was naturally drawn to viticulture and oenology to study vine growing and oenology at the École Nationale Supérieure d'Agronomie of Montpellier.
Jean-Baptiste Lecaillon joined Champagne Louis Roederer in August 1989, at which time he was one of the key people involved in selecting the site for Roederer Estate, in California's Anderson Valley.
After a year in California, he returned to Champagne to survey Roederer's 1990 harvest. In October of 1990, Jean-Baptiste Lecaillon left for Australia where he managed a subsidiary company of Champagne Louis Roederer until December 1993.
In 1994, Jean-Baptiste Lecaillon returned to Reims where he has an ever-increasing role in the making of the Louis Roederer Champagnes. Simultaneously, he ensures the development of the Roederer-owned Bordeaux properties: Château de Pez, Château Haut-Beauséjour and more recently Château Pichon Longueville Comtesse de Lalande.
In 1999, he was appointed Chef de Caves at Champagne Louis Roederer. Since 2006, he is Executive Vice-President in charge of the production of all the Roederer properties.
