Chateau Greysac's destiny is linked to a visit in 1973 by Baron Francois de Gunzburg and several of his friends. The visitors were so taken with the estate that they immediately decided to buy it. Chateau Greysac underwent remarkable development and was admitted to the very select Union des Grands Crus de Bordeaux in 1982.
Greysac's wine is now more than ever before the expression of its outstanding soil: beautiful gravelly rises located in the hamlet of By. Winemaking is traditional, though all necessary modern equipment is available to provide a helping hand. The selection of wine to be sold under the Greysac name is very strict, rarely over 70% of total production. Even in difficult years, there is great consistency in the quality of these wines. The characteristic style of Greysac is one of great aromatic finesse combined with good, full body. Their wines exhibit straightforward, clean flavors and sumptuous fruit which acquire elegance and complexity over time.
