As part of his academic responsibilities, Dubourdieu was the director of l'Institut des Sciences de la Vigne et du Vin de l'Université de Bordeaux (English: Institute of Vine and Wine Sciences of the University of Bordeaux). The Institute is a multi-disciplinary research center where experts from the University of Bordeaux, l'Institut National de la Recherche
Agronomique (English: The National Institute of Agronomic Research) and l'Ecole Nationale des Ingénieurs des travaux agricoles (English: The National School of Engineers of Agricultural Work) work together to assist wine producers with the state of the art in technology, technique and economic modeling.[5]
Dubourdieu specialized in winemaking processes for white wines,[6] and has been called "wine's most famous scientist".[7] He played a leading role in the improvement of white Bordeaux wines, which as late as the 1960s were sweet and of low quality, to become "serious, potentially profound dry whites".[8] He was hired by Ernest Singer to oversee the creation of a dry Koshu wine.[9] Innovations proposed by Dubourdieu include organic farming, oak barrel fermentation with extended skin contact and improved bottling techniques.[10][11]

^Prial, Frank J. (October 18, 2000), "Wine Talk. A Case of Neglect: White Bordeaux", The New York Times, The lighter, fresher style of so many Bordeaux whites owes much to the work of the oenologist Denis Dubourdieu, who also owns Clos Floridene in the Graves. Mr. Dubourdieu was among the first to ferment white wines in new oak barrels and to extend skin contact with the wines while they fermented. Today almost all the chateaus producing white wine in the Graves use methods devised by Mr. Dubourdieu.
