Château Giscours is a highly regarded estate in the Margaux appellation of Haut-Médoc, north of Bordeaux city. In the 1855 Bordeaux classification, it was rated as a Third Growth (3ème Cru), and since the 1990s, it has moved from being a Merlot-dominated wine to a more long-term blend, typically 75% Cabernet Sauvignon and 25% Merlot.

The estate has been owned and gradually rebuilt by several owners. The first records of vineyards here date back to the mid-16th century. In 1654, Louis XIV passed through here, and when he tasted the excellent wine from Giscours, he spoke highly of it. The estate was later managed by the Saint-Simon family, who had been going through turbulent times for some time. It only received new and ambitious projects in the second half of the 20th century. Dutch wine merchant and enthusiast Eric Albada Jelgersma took over the estate, restored the vineyards, and dedicated considerable effort and money to the winery. Within ten years, the winery managed to get back on its feet.
