I don't know about you, but I am particularly intrigued that an outfit as traditional and pivotal as Domaine Leflaive in Puligny-Montrachet was one of the first Burgundian domaines to blow its biodynamic trumpet. I suspect it is mostly down to the strong, non sheep-like personality of Anne-Claude Leflaive, backed by Pierre Morey, estate manager from 1989.
But the transition from conventional viticulture to organic to biodynamic was talked about much sooner than it was fully achieved so I have always been a bit confused as to exactly which vintage marked the transition. I recently asked Anne-Claude to enlighten me...
