Chateau Doisy Daene
Barsac has a lot of famous chateaux and wine families, like Doisy-Daëne: a chateau from a family that has been teaching Bordeaux how to make white wine for decades. Château Doisy-Daëne is a second-growth winery located in Barsac, a sweet wine-producing region within the Sauternes area south of Bordeaux, and has been owned by the Dubourdieu family since the 1920s. Born in Barsac and raised on the estate, Denis Dubourdieu became a professor of oenology at the University of Bordeaux and was one of the most sought-after winemaking consultants in the region until his death in 2016. The wines here are sweet, Sémillon-led-style wines made from grapes infected with Botrytis (mold) and aged in oak barrels. These oak barrels are sometimes given a second life, as distillers purchase used Sauternes barrels; in fact, Doisy-Daëne's barrels were eventually used to age single malt whiskey.
From Georges to Jean-Jacques
Georges Dubourdieu purchased Château Doisy-Daëne in 1924. Three generations later, the estate remains in family hands; considering that it is a classified Bordeaux estate, this is rarer than it might seem at first glance.
Denis Dubourdieu was born in Barsac in 1949 and grew up on the estate, learning from his father, Pierre. After studying agriculture and economics at Montpellier, he earned his master's degree from the University of Bordeaux, specializing in Oenology. In 1978, he completed his doctoral dissertation on the molecular structure of grapes infected with Botrytis, and four years later, he earned a second doctoral degree on the filtration and purification of wine infected with Botrytis.
In 1987, the University of Bordeaux appointed him as Professor of Oenology, and in 2009, he became the first director of the Institute of Vine and Wine Sciences in that city. He earned the nickname Professor of Bordeaux, taught two generations of winemakers now active around the world, and provided consulting services to numerous châteaux while running his own winery. His research on white wine production and aging revolutionized the winemaking process for white Bordeaux. After a long battle with illness, he passed away in July 2016 at the age of 67.
Currently, Jean-Jacques Dubourdieu operates the family-owned vineyards, which have been consolidated under the name Denis Dubourdieu Domaines. Sémillon leads the blend at Château Doisy-Daëne. Sauvignon Blanc plays a supporting role, adding acidity and a slight tang to wines characterized by their richness.
Winemaking
Botrytis is where it all begins. Botrytis concentrates the sugar in the grapes and alters their chemical composition; the two doctoral dissertations written by Denis Dubourdieu on Botrytis-infected grapes and Botrytis wine clearly demonstrate how seriously Château Doisy-Daëne takes this process. This wine is fermented at high sugar levels and aged in oak barrels, resulting in a full-bodied flavor. One classified vintage finished with an alcohol content of 13.5%.
Used Sauternes oak barrels are among the most expensive used barrels in the spirits industry, trading at approximately 300-400 euros each. This is because the residual sugars remaining in the wood are believed to enhance the whiskey's flavors of apricot, hazelnut, and truffle.
The oak barrels owned by Doisy-Daëne were used in a single malt released in 2021 by Aux Accents Vignerons, a project led by consultant and whisky affineur Aymeric Roborel de Climens. This bottling was named after the grape variety Sémillon. Because there are barrels that are not from Sauternes but tagged as from Sauternes, the Jean-Jacques Dubourdieu appellation control agency is developing a certification system that uses QR codes to verify a cask's origin and previous usage history.
