In 1734, Jacques Fourneaux established a wine-business in Champagne and worked closely with the Benedictine Abbeys which, at that time, owned the finest vineyards in the region. After the First World War, the wine-house was moved to a large mansion on the Rue de Tambour in which Theobald I of Navarre (1201–1253) had lived. A long-standing legend held that it was he who brought the Chardonnay grape from Cyprus on returning from a crusade in the Middle Ages. This has been disproved by genetic analysis done at the University of California at Davis. The Taittingers were a family of wine merchants who, in 1870, moved to the Paris region from the Lorraine in order to retain their French citizenship after the Franco-Prussian War and the Treaty of Frankfurt (1871). In 1932, Pierre Taittinger bought the Château de la Marquetterie from the wine house of Forest-Fourneaux. It had been used as a command post during World War I and he had been laid up there after suffering a heart-attack during combat. The vineyards of the château had been planted with Chardonnay and Pinot noir since the 18th Century. This property had been developed by Brother Jean Oudart, a Benedictine monk, one of the founding fathers of champagne wine, and later it had belonged to the writer Jacques Cazotte. From 1945 to 1960 the business was run by Pierre's third son François. Under his direction, the Taittinger cellars were established in the Abbey of Saint-Nicaise, built in the thirteenth century in Gallo-Roman chalk pits dating from the fourth century. After François' death in an accident, his brother Claude took over and directed the business from 1960 to 2005. It was during this time that Taittinger became a champagne house of world renown. Champagne Taittinger was sold in July 2005 by the Taittinger family, along with its subsidiary, Société du Louvre, to the U.S. private investment firm Starwood Capital Group. Those in the profession (Champagne houses, wine-producers, cooperatives, distributors and customers) proposed that the objectives of short-term profitability, or even medium term, at any price, advocated by the then current managers of the business, were not compatible with the production of Champagne wine of quality, which takes time, trust and a large delegation of authority to the masters of the cellar. In addition, the arrival of investors completely foreign to the culture of Champagne could result in a major breakdown of the equilibrium of the industry. Finally, on 31 May 2006, the Northeast Regional Bank of the Crédit Agricole, in collaboration with Pierre-Emmanuel Taittinger, bought the business for 660 million euros. The area covers 288.84 hectares of vineyards and has 12 to 13 million bottles in stock. The Château de la Marquetterie and its cellars were part of the overall purchase. The Starwood group retained some hotels, including luxury hotels Crillon, Lutetia and Martinez, and the hotel chains Campanile and Kyriad. Claude Taittinger retired in 2006 and his nephew Pierre-Emmanuel Taittinger replaced him as head of the business.
