The Duc de Mouchy, who formerly served as the managing director of Chateau Haut Brion, died at the age of 88 on February 28th.

Philippe Francois Armand Marie de Noailles was the second husband of Princess Joan of Luxembourg, whose family bought Haut Brion in 1935, Decanter reports.

He became managing director of the Premier Cru wine producer, as only blood relations of the Dillon family are allowed to sit on the board, and the pair went on to acquire Chateau La Mission Haut-Brion, Chateau Laville Haut-Brion and Chateau La Tour Haut-Brion.

Meanwhile, Joan's son by her first marriage, Prince Robert of Luxembourg, continued the family wine tradition when he became president of Domaine Clarence Dillon in 2008.

The Duc de Mouchy is survived by his three children, including Antoine-Georges-Marie de Noailles, the inheritor of his father's title.

Recently, the Board of Premier Cru Fine Wine Investments told moneyhighstreet.com that it believes Chateau Haut Brion 2006 will rise in value by 30 per cent by Christmas 2011.
