Anticipation through research
Bordeaux has been investing in research for more than 10 years
• PRESS KIT VINS DE
- CIVB 2020 •
The first work was funded in 2003 with a first thesis defended in 2007 on the climatology of the Bordeaux vineyard. Since then, the theme of climate change has been a common thread in the CIVB’s research priorities. It is based around 3 areas: • Climate • Oenological impacts • Plant material In total, nearly €2m has been invested in these areas over 10 years of research.
FOCUS ON research relating to plant material: VITadapt and GREFFadapt Conducted by the ISVV* in partnership with INRA and Bordeaux Science Agro, two projects in progress aim to study the behaviour and adaptive capacity of the vine in situ, in the face of global warming and in the climatic context of the Bordeaux vineyard.
GREFFadapt:
Study plot of 55 rootstocks including 30 authorised in France and 25 from abroad. All of these 55 rootstocks were grafted with 5 grape varieties emblematic of the French vineyard (Cabernet Sauvignon, Grenache, Pinot Noir, Syrah, Ugni Blanc). The objective is to determine the agronomic qualities of these rootstocks and in particular their adaptation to water stress.

VITadapt: this is a study plot planted on the INRA Nouvelle-Aquitaine site in Bordeaux in 2007 made up of 52 French and foreign grape varieties (Vitis vinifera). The Plot 52, examples objectives are to: of grape varieties • Measure any changes in the planted: Castets, quantity of grapes over time. Marselan, • Study the behaviour of Arinarnoa, SaintBordeaux grape varieties in the Macaire, Fer context of climate change. Servadou, Petit • Study the possibilities for Manseng, Liliorila, in white. adaptation and the quality potential of these grape varieties, little known in Bordeaux. • Record and archive observational data for these grape varieties. • Establish a ripening chronology for a large number of these grape varieties and quantify their physiological response to drought.

The 6 grape varieties included in the specifications of the Bordeaux and Bordeaux Supérieur AOCs are being tested on this plot.
Other examples of research carried out in
collaboration with the Bordeaux wine sector > HEATBERRY (INRA, University of Bordeaux): Impact of climate change on the phenology and quality of Bordeaux wines, with reproduction of a hotter climate using panels. > VITGREFSEC (Inra): To adapt the Bordeaux vineyard to climate change by choosing plant material that is more resistant to drought, without modifying the typical character of the wines produced. >AVVENIR (Inra, Bordeaux Science Agro, CNRS, University of Bordeaux) Developing a multidisciplinary and multi-scale approach to define the prospects in terms of grape composition, and assess at local level the adaptive potential associated with the environment and players on the ground. > MESOCLIMAT DU LIBOURNAIS (INRA, Bordeaux Science Agro) Impact of the local climate on a limited geographic area with a network of sensors. The differences observed (2°C annually on average) show that the choice of the location of the plot (orientation, altitude, etc.) is an important adaptation parameter. > NEWVINE (IFV, INRA Colmar, INRA Bordeaux) Creation of new varieties with typical Bordeaux character and resistant to the main fungal diseases (downy and powdery mildew) but integrating adaptation to climate change. *Institut des Sciences de la Vigne et du Vin
