Roussillon has a Mediterranean climate resulting in warm and sunny days, with strong tramontane wind, making ideal growing conditions for grapes and allows a high proportion of organic wines to be made here. The Côtes de Roussillon AOC covers the wider are and produces only dry red, white and rosé . Dominated by the Pyrenees, vineyards are planted on lower slopes of steep hillsides of limestone, schist and granite. Historically trained as bush vines with work done by hand which, although some are using trellising today, is still the common practice. The dominant grapes are Carignan, Grenache, Mourvedre and Syrah and wines must be made as a blend. The Côtes de Roussillon Villages AOC covers a much smaller area for red wines only and plantings on slightly higher slopes resulting in more acidity and concentration.
