Vieux Château Gaubert is a historic estate located in the heart of Portets, which was saved from demolition and preserved thanks to its classification as a French supplementary historic monument and its acquisition by Dominique Haverlan in 1988. The Gaubert family, prominent traders and shipbuilders in the 18th century, originally expanded the estate and transformed it into a significant vineyard. In 2004, the Pessac-Léognan vineyard was created with the acquisition of Château Pontet Caillou, adjacent to Domaine de Chevalier. This was a joint venture between Dominique Haverlan and Francis Dumigron, aimed at developing a vineyard on a parcel damaged by a storm in 1999. In 2010, Dominique Haverlan further expanded with the acquisition of Château Haut Pommarède, renovating both the property and the vineyard. By 2011, he took over the historic Château de la Brède, investing time and care into this storied vineyard. In 2018, Dominique's son Romain joined the family business after gaining experience in winemaking in the United States and New Zealand, becoming the fourth generation to carry on the Haverlan legacy in winemaking.
