In 1992, two years after their wedding, Sophie and Laurent Poitevin decided to take over the destiny of Château Grand Bert and Château Grand Tuillac. The two properties were handed-down from Sophie's parents and Laurent's parents in law, Philippe and Françoise Lavigne. Along with the properties, knowledge was also handed-down. Philippe Lavigne passed on all his know-how to Sophie and Laurent to uphold the family expertise. Over the course of the last 27 years Sophie and Laurent have kept on perfecting the wine fabrication and the management of the family business.
