In 1986 a new communal district was created within Graves, in Bordeaux, based on the districts of Pessac and Léognan, the first of which lies within the suburbs of the city. Essentially this came about through pressure from Pessac-Léognan vignerons, who wished to disassociate themselves from growers with predominately sandy soils further south in Graves.
Pessac-Léognan has the best soils of the region, very similar to those of the Médoc, although the depth of gravel is more variable, and contains all the classed growths of the region. Some of its great names, including Ch. Haut-Brion, even sit serenely and resolutely in Bordeaux's southern urban sprawl.
The climate is milder than to the north of the city and the harvest can occur up to two weeks earlier. This gives the best wines a heady, rich and almost savoury character, laced with notes of tobacco, spice and leather. Further south, the soil is sandier with more clay, and the wines are lighter, fruity and suitable for earlier drinking.
