The estate is located in the municipality of Barsac in the area Sauterne
(Graves, Bordeaux). The property dates back to the 17th century and was acquired by Elysée Nairac in 1777. After countless changes of ownership, there was a total decline in the 1960s with greatly reduced vineyards. Young Ohio-born American Tom Heeter worked up Château Giscours
to learn the winemaking profession. He got to know the daughter of the Nicole house and father-in-law Nicolas Tari bought the couple's winery. With the support of the oenologist Professor Émile Peynaud
(1912-2004) the dilapidated property was rebuilt. After the divorce and the departure of Tom Heeters in 1986, it is now managed by his son Nicolas Tari-Heeter. In the Bordeaux Classification
in 1855 the estate was classified as "Deuxième Cru Classé". The vineyards cover 17 hectares and are planted with Sémillon (90%), Sauvignon Blanc (6%) and Muscadelle (4%). The extremely long-lasting, noble sweet wine matures in 100% new barriques for up to 30 months. There is no second wine.
