The first mention made of Château Giscours dates back to around 1330 when it was referred to as a fortified dungeon. In 1552, the estate was sold for 1,000 pounds and was already recognised as a vineyard at this time. Reference is made in the Féret, considered as the bible of Bordeaux wines, of Giscours being served to Louis XIV who, it was said, appreciated the wine.

In 1789, the estate belonged to the Saint-Simon family, from whom it was confiscated in order to become "National Property". Numerous owners then followed, one of whom was the Count of Pescatore, a great Parisian banker, who ordered the rebuilding of the château in 1847 in a manner to receive the Empress Eugénie.

The 1855 classification ranked the wines of Giscours a Margaux 3rd classified growth.
Giscours passed from owner to owner, going through a period of decline which only ended when the estate was bought by Nicolas Tari after the Second World War. He undertook a general renovation of the estate, one of the most significant works being the creation of an artificial lake, which is today a key element in Giscours' microclimate. One of the most important tasks was to find an ecological balance for the vineyard. The restoration of the château was then carried out, followed by an overhaul of the vineyard and cellar equipment.

After a run of financial difficulties, the wine growing business of Château GISCOURS brought in the outside investment and acumen of Eric Albada Jelgersma, a Dutch businessman, together with his family.
Francophiles for many years now, they fell in love with the Médoc, and since their arrival have spent a part of their time learning the skills of vine growing and wine making. They have invested in the renovation of the vineyard and the cellars and have increased the capital. Eric Albada Jelgersma today owns 100 % of the Château Giscours wine growing business.

In January 2001, the business was awarded the certification of its quality system in accordance with the regulations of ISO 9002. This certification guarantees the quality of the wine production from the fermentation, as the grapes arrive at the vat cellar, to the packaging, storage, and shipment of the wine to the customers. This constitutes a commitment to care and attention and to permanent progress in the field of quality.

Château Giscours was the first of the Bordeaux classed growths to take this bold, modern and innovative step.
