On the eve of the 1997 harvest, Jean-Hubert DELON buys Château Nénin, until then owned by his cousins, the DESPUJOL family, since 1847. From this acquisition, a deep restructuring is undertaken. The size, the trellising of the vines were taken again, the drained soil, the vines complanted or torn off, the modernized material. The breeding and storage cellars have been completely refurbished, enlarged and air-conditioned. A new winery, equipped with the most advanced equipment, was built to crown the total transformation of the property.
