Étude des potentialités des terroirs viticoles: une démarche globale en zone A.O.C. L’exemple des Côtes du Rhône

Climate change projections point to an increase of temperatures and changes in rainfall patterns in the mediterranean region.

Sulfur dioxide (SO2) is used in winemaking due of its antioxidant, antioxydasic and antiseptic properties. Excessive amount of SO2 can negatively impact wine sensory perception and be detrimental for health. Agri-food industries are more transparent towards consumers concerning addition of sulfites, and oenology is no exception in this clairvoyance. As a consequence, the increase of consumers preference for wine with low or absent of sulfites addition is notorious. In this context, the impact of low/zero sulfites winemaking process on the microbial community should be evaluated. Moreover, microbial agents corresponding to bioprotective cultures represent a growing interest as an alternative to sulfites preservation in the early stages of vinification. However, scientific studies conducted to demonstrate their real effect are almost rare.

Eleven wine-growing sites are now on the UNESCO World Heritage List as Cultural Landscapes. If the viticultural character of these sites constitutes the main argument for the demonstration of their heritage value, the terroir and its biophysical and environmental characteristics tend however to appear in a minor mode compared to the aesthetic and cultural dimensions. In other words, the “specific characteristics of the soil, topography, climate, landscape and biodiversity” (OIV definition) are most often used as descriptive elements in the presentation of the sites, but it is more the aesthetic, historical,
