Pauillac ([po.jak]) is a wine growing commune (municipality) and appellation d'origine contrôlée within Haut-Médoc in Bordeaux, centred on the small town of Pauillac.Hugh Johnson has said, "If one had to single out one commune of Bordeaux to head the list, there would be no argument. It would be Pauillac.". Pauillac includes 3 of the 5 premier cru châteaux of Bordeaux: Latour, Lafite Rothschild and Mouton Rothschild. The wines of Pauillac are often considered the quintessence of Bordeaux wines.
Pauillac is on the left bank of the Gironde. St-Julien is to the south. A stream called Ruisseau de Juillac marks part of the boundary between the two communes; other parts are marked by a stone wall and a country lane. To the north, across the Jalle du Breuil, lies St-Estèphe. Pauillac is bounded on the west by the parish of St Sauveur and the Landes forest. All three communes lie within the Haut-Médoc. The town of Pauillac is the largest in the Médoc, with a population of over 5000. Pauillac is somewhat more elevated than the surrounding area, rising to a peak of nearly 30 metres above sea-level in the region of Château Pontet-Canet. The soil is gravelly, as with most of the Haut-Médoc. The forest to the west shelters the vines from the Atlantic winds. Pauillac contains around 1200 hectares of vineyards.
