Jeanne Gibourg married Andre Mugneret in 1928 and together they founded Domaine Mugneret Gibourg in 1933. Their only son, Dr Georges Mugneret, embraced the family profession alongside his medical career. His vision has enlarged and enhanced the family estate by acquiring new plots. Noteworthy acquisitions included Clos Vougeot Grand Cru in 1953 and Ruchottes Chambertin Grand Cru in 1977.

Georges met his future wife Jacqueline, who was a school teacher, in 1958. They had two daughters Marie Christine and Marie Andree. After Georges death in 1988, Marie Christine took over the activity with her mother Jacqualine, Marie Christine later earned a diploma in oenology.

In 2009, Domaine Mugneret Gibourg and Georges Mugneret merged, creating Domaine Georges Mugneret Gibourg. Today, the estate is headed by sisters Marie Christine and Marie Andree, with their respective daughters Lucie and Marion joining the team in 2017 and 2018.

The Domaine spans 8 hectares across 9 different appellations. The sisters employ a gentle and classical winemaking approach, preserving the grape's inherent delicacy, fruitiness, and freshness. They have chosen to cultivate the soils by ploughing, allowing the vine roots to penetrate deeply and robustly, drawing the essence of the terroir into the grapes. From May onward, they undertake the meticulous task of nurturing the vines, ensuring optimal growth and flowering, leading up to the harvest in September.

Among their three Grand Cru holdings, Ruchottes Chambertin stands out as the finest wine. Georges Mugneret acquired this small plot (two-thirds of a hectare) at the end of the Combe le Lavaux in 1977, with the help from Charles Rousseau. Planted in thin, stony soil rich with rocks. It is a magnificent wine of great intensity, length and aging potential. The great Henri Jayer once said this wine is like “A Chambertin raised in Vosne”.
