Created in 1638, Château Léoville Las Cases produces some of Bordeaux's most prestigious wines. They were already well-known, much appreciated and commanding high prices in the middle of the 18th century, due to work of the owner, Blaise-Alexandre de Gasq, the Seigneur of Léoville. Four of his descendants owned the property at the time of the French Revolution. One of them, the Marquis de Las Cases, who owned one quarter of the land, fled abroad. The other three managed to obtain a partial confiscation of the property, consisting specifically of this quarter, from the Revolutionary Government. This plot would later become Léoville Barton. At the beginning of the 19th century the property was split once again and the half adjoining Château Latour formed the current vineyard.

Léoville Las Cases produces a wine of incredible complexity. To achieve the best possible quality, a large proportion of the production is always downgraded (up to 67% in the 1990 vintage). The wines are extremely consistent and approach perfection in most of the great vintages. Deeply coloured, tannic, full-bodied and concentrated, they have a huge potential to age. These are grandiose wines.
