This wine comes from an estate owned by Domaines Lafragette. Many Chateaux in Bordeaux are owned by corporate entities, though they still produce wine from their own vineyards, which is indicated here -- as Chateau Loudenne is listed as a propriétaire récoltant, or harvester of their own fruit.
Many Chateaux also have remained family owned and many labels have been created by négociant, entities that buy grapes and finished wine, and then bottle it as their own wine under a proprietary name.
The region here is the Médoc, a name used to cover almost all of Bordeaux's left bank. There are smaller regions that fall within the Médoc, each with their own appellation.
Some of the most famous appellations of Bordeaux include Margaux, St. Julien, Pauillac, St. Estephe, Pomerol, St. Emilion, and the Graves region.
The Sub-Region or Appellation
The Appellation, in this case Médoc, is a region where many aspects of a wine are regulated. The purpose of attaining Appellations d'origine contrôlées status is to ensure the consumer that certain benchmarks have been met.
In this case they would be that this wine is from the stated estate that falls within the Médoc appellation, was made with some combination of approved grapes ( Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, Petit Verdot, and Carmenere), that are planted and pruned according to specific guidelines, has achieved a specifed sugar level at ripeness and a corresponding minimum alcoholic content, and has been aged for the appropriate length of time.
The Classification of the Estate
This wine is listed as a Cru Bourgeois. After several years in legal limbo this classification is returning to wine labels with the 2009 vintage.
This classification is only one of six presently used for Bordeaux wines. The most famous is the 1855 classification of the wines of the left bank.
In addition there are the classifications of Graves, St. Emilion, the Cru Bourgeois, the Cru Artisans, and a new small group known as Les Exceptionnels.
While some of these classifications fairly accurately represent the quality of the wine in each bottle, no classification is perfect and this should not be taken as a guarantee of quality
