The integration of local climate variability (bioclimatic indices and phenological modelling) into regionalized climate change simulations provides an assessment of the impacts of climate change at the vineyard scale. The knowledge gained using this methodology is the increasing horizontal resolution that better suits the winegrowers concerns. Overall conclusion highlights the fact that thermal differences within each site are similar to the thermal differences simulated by the climate model between 1986-2005 and 2031-2050 (increase of 200-500 GDD) and between 1986 and 2081-2100 (increase of 500-1000 GDD). Hence, these results give the local winegrowers/stakeholders information necessary to understand the current functioning as well as historical and future viticulture trends at the scale of their site that may facilitate decisions about future strategies.
