In the Bordeaux region the classified crus have mixed soils, but large enough tracts of land to make very rigorous selections. It is only the quest for excellence during the XVIIIth century that led the owners to elaborate several wines of different quality. Severe selecting is the guarantee of quality of a great wine, but also of a second wine.
Today, the second wines represent between 20 and 50 % of the total production of the Chateau. From the same soil, the second wine benefits from the same technology as the great wine, and also its reputation. They are generally excellent wines, though less robust and long lasting than their elders.
The archives kept at Chteau Pichon Longueville Comtesse de Lalande mention the existence of a second wine as early as the XIXth century
:The second wine of Pichon Longueville Comtesse de Lalande, The Rserve de la Comtesse, was created and sold for the first time in 1973
