The wines are kept in vats to preserve fruit aromas. They are racked regularly in order to allow their components to stabilise naturally.
The "Saint Esprit" cuvée is bottled after 8 months of ageing.
Vineyards : they cover about 41,200 hectares/101,764 acres (within 6 French "départements").
Climate : mediterranean with a prevailing "Mistral" wind. This harsh wind - both necessary and beneficial to the vines' development - is caused by the difference between the Southern and Northern Rhône's atmospheric pressures. Highly seasonal rainfall, hot temperatures and abundant sunshine are also the characteristic of this region.
