Languedoc-Roussillon Wine - Climate and Geography

Climate and Geography

The Languedoc-Roussillon region shares many terrain and climate characteristics with the neighboring regions of Southern Rhone and Provence. The region stretches 150 miles (240 km) from the Banyuls AOC at the Spanish border and Pyrenees in the west, along the coast of the Mediterranean Sea to the Rhone River and Provence in the east. The northern boundaries of the region sit on the Massif Central with the Cévennes mountain ranges and valleys dominating the area. Many vineyards are located along the Hérault River.

Vineyards in the Languedoc are generally planted along the coastal plains of the Mediterranean while those in the Roussillon are to be found in the narrow valleys around the Pyrenees. The peak growing season (between May and August) is very dry and the majority of annual rainfall occurs during the winter. In the Languedoc, the plains area is the most arid and hottest region of France. The region's Mediterranean climate is very conducive to growing a large amount of a wide variety of grapes, with vintners in the area excelling in mass production. The average annual temperature is 57 °F (14 °C). The tramontane inland wind from the northwest often accentuates the dry climate; drought is the most common threat to vine production, with French AOC and European Union regulation prohibiting the use of irrigation. In December 2006, the French government responded to global warming concerns and relaxed some of the irrigation regulations.

In 1999 severe weather had damaging effects on the wine producing industry, including hailstorms in May that affected Roussillon and a rain surge in mid November that saw a year's worth of rain fall in 36 hours in the areas of Corbières and Minervois in the western Languedoc.

The composition of soil in the Languedoc varies from the chalk, limestone and gravel based soils inland to more alluvial soils near the coast. Some of the more highly-rated vineyards are laid on top of ancient riverbed stones similar to those of Châteauneuf-du-Pape.
