Wine growing terroirs: management of potential. New issues at stake for AOCs in France

Abstract

Terroirs represent a heritage that must be studied and managed with appropriate methods; recourse to agronomic and oenological sciences alone is necessary, but is in no way sufficient without the contribution of the humanities.
The wine growing terroirs have undergone five major transformations in the space of 150 years, but nowadays we are witnessing a threefold pressure in terms of change concentrated over a short period:
– climate change, altering the « vine varieties – environments » correlation.
– a change in wine consumption habits, especially among young people and throughout the world.
– the emergence of environmental concerns with their consequences on the chemical means used to combat the enemies of the vine.
To rise to the challenge posed by these changes, recent research results must be taken into account by the AOCs, considering not the techniques in isolation, but the socio-technical itineraries all along the chain of potentialities in the production process from the grapes to the wine in the glass. To the extent that AOCs put in place collective structures for controlling the vine vigour and furthering the integrated control over their demarcated areas, they will be rapidly able to meet the challenges presented by these change-related pressures. Recent results have made it possible to support initiatives by producers and are meeting with success: several examples are analysed and discussed.

Climate change projections in serbian wine-growing regions

Application of nitrogen forms such as nitrate, urea, and amino acids effects on leaf and berry physiology and wine quality

Nitrogen (N) uptake by grapevine roots in forms like nitrate, ammonium, urea, or amino acids influences vegetative and generative growth, impacting grape quality and wine sensory profile. The study examined nitrogen’s influence on phenolic compounds in leaves, berries, and wine across different scales — hydroponics, soil culture, and vineyard trials. Nitrogen forms altered metabolite patterns in leaves and wine significantly, affecting aroma and flavor. Key nitrogen assimilation enzymes (NR, NiR, GS) in grapevine rootstocks responded to nitrogen forms and timing. Hydroponically grown rootstocks fertilized with various forms showed differences in enzyme expression and activity, suggesting rootstocks can assimilate amino acid glutamine (Gln).

Etude préliminaire des influences pédoclimatiques sur les caractéristiques quali-quantitatives du cépage aglianico dans une zone de la province de benevento-ltalie

The need to classify the vineyards of an area according to the quality of its wines is not recent, but it is only in the last ten years that studies on the suitability of different areas for the cultivation of vineyard take on an integrated and interdisciplinary character (Boselli, 1991). The definition of the suitability of the environment is thus obtained by making the climatic, pedological, topographical and cultural information interact with the vegetative, productive and qualitative expression of the grape varieties.

What happens with the glutathione during winemaking and the storage of the wine?

We tried to give a part of the answer to this question by monitoring glutathione during winemaking and storage. The novelty of our approach is to quantify simultaneously the three known forms of glutathione: free glutathione (GSH), oxidized form (GSSG) and glutathione-S-sulfonate (GSSO3H).

Methodology for soil study and zoning

La caractérisation des sols en vue d’une étude de terroirs viticoles peut être réalisée à différents niveaux de complexité, suivant le nombre de variables pris en compte et suivant le fait que celles-ci sont spatialisées ou non
