Château Giscours, is a Troisième Grand Cru Classé in the commune of Margaux.   The estate dates to the middle ages, but by the mid-twentieth century it had fallen into disrepair, with just 1-0 hectares producing fruit.   In 1954 it was bought by Nicholas Tari, who began the restoration of the vineyards.  In 1995 Giscours was sold to Dutch businessman Eric Albada Jelgersma (also the owner of du Tertre, until its sale in 2021).  He died in 2018 but the estate continues in his family's ownership.

The 90 hectares of vines are on Garonne gravel and are planted to 60 % Cabernet Sauvignon, 32 % Merlot, 5 % Cabernet franc and 3 % Petit Verdot.  Alexander Van Beek has managed the estate for some years and is credited with improving quality greatly.
