In 1960, the young winegrower Lucien Liebart settled with his wife Georgette Regnier in Baslieux sous Chatillon , a typical little village in the Marne Valley, and together they founded the LIEBART-REGNIER Champagne House. When his father died in 1987, Laurent naturally took over the family vines, and was later assisted by his wife Valérie.

As an independent winegrower, Laurent works hard to ensure that his champagnes reproduce the expressiveness of their land. Laurent respects the environment and has turned to integrated vine growing. He is curious to learn and use alternative techniques such as incorporating lunar cycles during planting, tilling, cover planting, sexual confusion and so on, putting these methods into practice to cultivate his vines.
