Libourne, small port on the right bank of the Dordogne in the Bordeaux region. It is now the commercial centre for the right-bank appellations, although it was established in the 13th century, much later than st-émilion’s port Pierrefitte, and was at the time considered a parvenu in comparison with fronsac. In modern history, its wine trade is much more recent than the Chartronnais of the bordeaux trade in the great city across the Garonne, and its more modest traders concentrated initially on selling in northern mainland Europe rather than in the British Isles. Of merchants based here on the banks of the river Dordogne, J. P. moueix is the most important. For more details, see pomerol, the wine region on the eastern outskirts of the town.
