Chateau Lanessan's origins date all the way back to 1793, when it was founded by Jean Delbos, a Bordeaux wine merchant. The property only spanned 24ha at its inception, with the famed Tudor-style chateau only being constructed nearly a century later in 1878. Remarkably for a Medoc estate, Chateau Lanessan remains in the hands of its founding family to this day.

Lanessan is renowned for its traditionally-styled wines. In recent years, quality has been at the forefront of thinking at the estate, with the family bringing in Hubert do Bouard, owner of Chateau Angelus, as consultant. Vineyards are 60% plantings of Cabernet Sauvignon, 35% Merlot, 4% Petit Verdot and 1% Cabernet Franc, with an average vine age of 30 years. Due to the wine's traditional Bordeaux style, consumer-friendly price and ability to age for decades, it has remained a popular Left Bank choice to this day.
