The history of Chateau Pichon-Longueville Baron is a tale of two estates. The chateau and vineyard known as Pichon Baron was given in dowry to the founders daughter when she married Jacques du Pichon Longueville. After the death of their descendent, the Baron Joseph de Pichon Longueville, in 1850 the estate was again divided - on his deathbed, he gave what became Chateau Pichon Baron to the men of his family, and what became Chateau Pichon Lalande to the women - resulting in, some say, more masculine and sensuous styles of wine respectively! Between the 1960s and the 1980s, the estate went through a period of rather lacklustre production - however, since 1990, they have been producing, according to many, some of the best wines in their history. The 2016 has earned high praise and glowing comparisons to their legendary 1990 Pichon Baron.

One of the original Second Growths of the Bordeaux Classification of 1855, Rauzan-Ségla's 51 hectares of mineral rich soils begin on the banks of the Gironde, on the left bank of Bordeaux. A complex mix of gravel, clay and limestone subsoil imparts a richness and complexity to the Cabernet (62%), Merlot (36%), Cabernet Franc (1%) and Petit Verdot (1%) grapes used to produce this powerfully intense and elegant wine. The estate was last sold in 1994 to the Wertheimer family of Chanel, who employed former Château Latour winemakers, David Orr and John Kolasa. Nicolas Audebert, the former winemaker at Cheval des Andes, the LVMH property in Mendoza Argentina, was hired to succeed John Kolasa following his retirement in 2014.

The second wine of Chateau Mouton Rothschild was first released in 1993. Le Petit Mouton takes its name from a small house next to the main Chateau, the official residence of Baron Philippe Rothschilds wife and family. The Chateaus modern age began in 1922 producing vintages through what were, at the time, cutting-edge techniques; though seen as revolutionary at the time, many of these methods are still in use today. This includes the groundbreaking concept of bottling all wine on the estate, allowing for an unprecedented level of control over the Bordeaux sold from Mouton-Rothschild.
