The Mongeard family arrived in Vosne-Romanée in the 18th century, and records show a Mongeard working as vigneron for Domaine de la Romanée-Conti in 1786. In 1945, Jean Mongeard, whose mother was a Mugneret, found himself making wine at the age of 16. His father had died five years before, and there was no one left to do the job. The entire 1945 crop was purchased by Baron le Roy, Marquis d'Angerville, and Henri Gouges. Gouges instructed the young Mongeard to personally bottle the wines, rather than sell them in barrel, because of the exceptional quality of the family's wines.

Owing to the situation of the vineyard, Vosne Romanée's premier cru "Les Petits Monts" is a wine of great complexity. With a discreet acidity and fine tannins, this wine is characterised by perfumes suggestive of ripe fruits and the essence of flowers. Scents of woodland undergrowth and humus mingle with those of cherries in brandy and peony, later tending towards perfumes of leather and animals. Sometimes smoky, in the mouth, it is ample, pure, and velvety. Its finesse and elegance make it a very harmonious wine.
