Chateau Lafleur did not get its start in the 20th century. The history of Chateau Lafleur dates back to 1872. At that time, Henri Greloud, the owner of Chateau Le Gay, purchased the Pomerol vineyards of what was to eventually become Chateau Lafleur. Small, ultra-prestium Bordeaux wine estate located in the Pomerol appellation on the Right Bank of the Gironde. Despite not having an official classification (Pomerol has no formal ranking system), Lafleur is widely considered among the very top wines of Bordeaux, often fetching very high prices on the secondary market and commanding intense interest from collectors worldwide.

The Pomerol region is located at the northern border where viticulture was present in the area during the time of the Romans. Though it is uncertain as to the origins of the name "Pomerol", but it is speculated that the word was derived from the Latin word poma, which refers to a fruit bearing seeds and is the origin of the French word pomme, meaning apple. This theory is supported by the region's long history of polyculture with many other crops, particularly fruits and grains, being cultivated in the area long before viticulture became a primary focus.
