Caractérisation et gestion de la maturation par terroir en Champagne

Climate change will increase the frequency of water deficit experienced in certain european regions, due to increased evapotranspiration and reduced rainfall during the growing cycle. We therefore need to find ways of adaption, including the use of more drought-tolerant planting material. In addition to the varieties used as grafts and involved in the wine ypicity of our wines, rootstocks selection is a relevant way of adapting to more restrictive environmental conditions.

Wine minerals, including calcium, derive mainly from grape berry extraction, but they could also arise from winemaking additives, processing aids, and other sources.

Sulfites (SO2) are commonly used in the wine industry to preserve products during storage for antiseptic and antioxidant purposes (Oliveira et al., 2011).

An experiment was carried out to test the relevance of using satellite images (NDVI) to define locations of plant monitoring systems.

Understanding the water-use responses of grapevines to increasing atmospheric carbon dioxide concentrations is mandatory when assessing the impact of climate change on viticulture as it is a critical part of the adaptation process.
