Grand Puy Ducasse (pronounced "Gran Pwee Ducass") or Chateau GPD for short is a 5th growth wine from the Pauillac region. It was started when Arnaud Ducasse purchased a house next to the Gironde river from Jacques de Segur in 1675 (who at that time owned the Lafite estate at that time).
When Bordeaux wines were ranked/classified in 1855, the winery had been sold to other owners so at that time, the winery was called Chateau Artigues Arnaud. In 1932, the owners changed the name to Grand Puy Ducasse to honor the name of the original owner and the place. The vineyard is located on Grand Puy (or big mountain), which is actually a low gravely hill. Also situated on this hill is Grand Puy Lacoste, another 5th growth winery that was actually known in 1855 as Grand Puy.
The winery is quite unique in that a lot of its vineyards are not located at the chateau. They have about 40 hectares of vineyards located in 3 major locations: 1 site near Lafite/Mouton, 1 site near Pontet Canet/D'Armailhac and 1 site near Pichon Baron/Lynch Bages.
The winery has a lot of ownership changes but in 2004, Credit Agricole purchased the winery. In 2013, they brought in Hubert de Bouard of Chateau Angelus as their consultant.
The winery makes about 10,000 cases of this wine each year. The 2017 vintage is a blend of 57% Cabernet Sauvignon and 43% Merlot. The wine is aged in oak (50% new barrels) for 18 months.
