90% of Châteauneuf-du-Pape’s production is red, principally utilising grenache noir and often with the support of syrah and mourvédre. The land is relatively flat with the highest altitudes being some 120m above sea-level. The common factor to all areas is the heat of the growing season, made even more arid by the action of the mistral winds which carry away moisture. Temperatures during the growing season can reach 40 degrees celsius, and ripeness in the grapes is rarely a problem, particularly in those terroirs where the galets act as storage heaters, soaking up the heat of the day and radiating it back at night.
