Region	Moulis -Surface: 353 ha. -Only wines from the defined parcels in the communes Listrac, Lamarque, Arcins, Avansan, castelnau, Cussac. -Only red wines -Grape varieties: Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, Petit Verdot. -Max. 40 hl. per ha. in production		The grape varieties The châteaux Calcareous clay with gravels. The soil is dominated by the gravel mounds that are so typically for the Médoc. These mounds afford excellent drainage of water and are loose and airy. Because of its infertility the gravel mounds encourage the vines to send its roots down deep in search of nutrients. These gravel mounds rest on (starfish) limestone (Calcaire à astéries) plateaux. Moulis has a maritime climate, caused by the Atlantic. The warm Gulf Stream and the Gironde act as a heat-regulator and moderate the climate. This gives the region mild winters, warm summers, and long, sunny autumns. The region is protected from sea winds by the coastal strip of pine forest which runs almost parallel to the region. The oceanic influence places the region in a very privileged position with few unwelcome extremes of temperature. Much to the concern of the vignerons however, harvest time and the rainy season arrive about the same time. If the rains come early all grapes will not be fully ripened. If the rains come during harvest, the grapes can lose concentration. The record keepers have observed that in any ten-year span there will be, from a climate point of view, three great years, three poor years, and four that are mediocre. Sometimes the normally mild region is rudely reminded of its northern latitude. In February 1956 a hard frost occurred with temperatures below -18º C (0F). There is also the lingering concern that the Saint de Glace may visit the budding vines in the first weeks of May. Like in 1991.
