From 1500 to 1809 Mayne-Vieil belonged to the DE PATY family. The squire DE PATY, Lord of Mayne-Vieil, built the winery in the 17th century. It was eventually replaced in the 18th century  by the fortified house with an elegant chartreuse that currently stands on our grounds today.

Mayne-Vieil was then purchased by the Fontemoing family; a group of renowned vintners from Libourne. They created a new Fronsac vineyard which produced the so-called "new french claret"-high and aged wines similar to those being produced by the English merchants from the Chartrons in the Médoc.

In 1918, Louis SEZE acquired the property. A few years later, he abandoned his notary office to devote himself to Mayne-Vieil. His son Roger, an agronomist who succeeded him in the early 1950's, expanded the vineyards to make a contigous and beautiful plateau . He was the first proprietor of Mayne Vieil to begin bottling and selling the wine directly to private clients.

His children Bertrand  and Marie-Christine Sèze succeeded Roger SEZE in the 1980's. They enlarged the domain of Mayne Vieil to more than 10 hectares (24.7 acres), and increased its international presence-particularly in the United States, China and Western Europe.
