Contemporary of Henri IV and his descendants, the Hémart family settled permanently in Aÿ at the beginning of the 17th century. Their history took root there and became closely related to the extraordinary history of Champagne from the 18th century.
At the beginning of the 20th century, Léon Giraud, cuirassier in the battle of the Marne, married a Lady Hémart.
He reconstructed the magnificent family vineyard, which had been ravaged by phylloxera. To achieve this, he used the latest techniques : the grafting of vines (vitis vinifera) on the cuttings taken from certain American vines.
Today, the 12th generation of the Giraud-Hémart family, in the person of Claude Giraud, is in charge of the fortunes of the family business.
