The Chastellier family belongs to Breton nobility. In 1723, Charles de Chastellier owned a namesake seigneury in the parish of Vieu-Vel, in Brittany. His son Amaury, an equerry of King Louis XVI, was appointed Grand Equerry of France in 1776. He was in charge of the royal stables and personally managed the top stable of Versailles. Renowned for his hard work and leadership skills, he was appointed head of the King's Pages School in 1782. Located in Reims, the ‘City of Coronations’, the school trained future cavalry officers.
After 7 years at the institution’s helm, the king appointed him Lord of Muire, in Champagne. Subsequently, Amaury's youngest son, Etienne, had a chateau built on the banks of the Vesle and an adjoining estate covering over 80 hectares. He became the owner of several Champagne houses in Reims, including the Pavillon de Muire, now owned by Veuve Clicquot Ponsardin. Beneath the pavilion are lavish vaulted cellars, where keen Champagne enthusiast Etienne Chastellier kept his finest growths.
Some of the vineyard land from the seigneury of Muire remains to this day, primarily in the village of Bezannes, in the south of Reims, where Domaine De Breux is located. This 12-hectare property has belonged to the Chastellier-Ronsin family for 8 generations. Frédéric and his wife Aurélia, who have run the estate since 2016, have chosen to name their top Champagne after their first-born son, Rémy, in keeping with the family tradition.
