The proliferation of Phylloxera in the late 1800's gradually killed the vines and the death of General BATAILLE on the Vosges front in 1914 led to the abandonment of the 300 Ha of Chambert vineyards.

From 1914 to 1973, the vineyard area became fallow land for sheep grazing and, paradoxically, this unfortunate abandonment was a blessing in disguise since the land escaped the intensive chemical agriculture phase of the inter-war and post-war periods. The Chambert site was untouched by chemical treatments, the land was saved, untreated, and ready to start over at the first opportunity.

In 1973, Marc DELGOULET, a wine maker from the Correze is captivated by the charm and historical grandeur of Château de Chambert and purchases the château and the surrounding hillside. His goal is to return Château de Chambert to it's former glory and produce the wines that were once again appreciated around the world . In 1974, he selects the best parcels of land with the best exposition, slope and soil type and replants the hillside around the château with Malbec. The vineyards are managed organically: worked by hand, treated with minimal sulfur and fertilized only with a natural compost.
Marc's first vintage in 1978 produces a wine that goes on the win gold at the national competitions of Mâcon, Blaye and Bourg and he is well on his way to reviving the legend of Château de Chambert. Respectful of the vines and a lover of the land, in 1989 Marc contacts Jacques Mell of "Terres en Devenir", a consulting business for biodynamic farming. It is too expensive for Marc to venture into biodynamics so he continues along an organic path; however, little did Marc know that 25 years later biodynamics would become the destiny of Chambert. With the help of his son Joel, the two continue to improve the reputation of the estate and the wines of Chambert are still appreciated for their elegance, finesse and reflection of exceptional terroir.

Today the vineyard property, owned by Philippe Lejeune, covers about 65ha. It is the largest certified organic estate in Cahors (ECOCERT certification) and largest South-West biodynamic estate (DEMETER and Biodyvin certifications)

Since 2019, a new modern building suspended over the vineyard includes a VIP reception / tasting room, a biodynamic research lab and a professional kitchen.
