Chateau Grand Mayne St Emilion A vineyard overlooked by a manor built at the end of the 16th century, Mayne can trace its 200-year history back to the Laveau family who acquired it in 1685. The attentive and loving care of Jean Laveau raised the vineyard to the highest level, as evidenced by the wine prices and praises in the Féret, the reputed 1846 Bordeaux wine directory.
