At the end of the 18th century, Jean de Boüard de Laforest—a member of the royal guard—settled in Saint Emilion. His daughter, Catherine Sophie de Boüard de Laforest, married Charles Souffrain de Lavergne in 1795, and the couple settled on the vineyard in Mazerat, which was her husband's property. At the beginning of the 20th century, Maurice de Boüard de Laforest inherited the vineyard estate and began to expand it. Notably, he added a three-hectare enclosed plot named ANGÉLUS in 1920. Monsieur Maurice bequeathed the entire estate to his sons. Jacques and Christian de Boüard de Laforest continued the work of their father and previous generations. The estate was classified in 1954.
The brothers expanded the vineyard, which reached an area of 20 hectares in 1985. At that time, Jacques's son Hubert took over the leadership of the estate, and in 1987, his cousin Jean-Bernard Grenié, Christian's brother-in-law, joined him. He was followed by his daughter Stéphanie de Boüard-Rivoal in 2012 and his nephew Thierry Grenié de Boüard in 2016.
