This is the section that most people think of as Bordeaux.  This area extends about sixty miles from the city of Bordeaux.  It has only been about two hundred years of wine production for the Medoc.  Bordeaux wines were originally known from the commune of Graves which is adjacent to the city; these were the wines that were known as Claret in England.

The Medoc is divided into two parts.  Bas Medoc (Lower Medoc) and Haute Medoc (Upper Medoc) and this are based on the elevation of the terrain.   Those wineries located in the Bas Medoc usually use the designation of Medoc, so as not to sound inferior.  The wineries in the Haute Medoc capitalize on the designation.

Once again here is just a collection of labels showing this designation.
