Soil Temperature and Climate Change: Implications for Mediterranean Vineyards 

Abstract

More frequent and extreme temperatures and droughts pose challenges to the wine sector in Mediterranean Europe. Soil is crucial to sustain the equilibrium of ecosystems, economic growth and people’s prosperity worldwide. In viticulture, soils are a major component of the terroir and do influence vine’s growth, yield and berry composition. Soil temperature (ST) affects soil´s physical, chemical and biological processes and also crop growth. The impact of ST becomes even stronger when dealing with row crops such as grapevine, when considering the increased exposition to radiation. However, the impact of ST on crop performance remains poorly described, especially for extreme climatic conditions. A better understanding of the role of ST in vineyards can help to better manage and predict the performance of vines, plant-soil relations and soil microbiome under extreme climate scenarios. In addition, climatic and thermal data (of plants, soil) can be integrated into Decision Support Systems (DSS) to support vineyard management. Improved soil characterization, improved practices of soil management and imaging (e.g. thermography) can be combined to support management. Strategies to mitigate the impacts of climate change, optimize ST variation and vine thermal microclimate (leaf and berry) are proposed and discussed, with emphasis on Mediterranean systems.

How to reduce SO2 additions in wine with the aid of non-conventional yeasts

Among the factors that influence the sensory quality, style, safety, sustainability, and sense of place of a wine, the contributions of microbial biodiversity are widely becoming more recognized. Throughout winemaking, multiple biochemical reactions are performed by a myriad of different microorganisms interacting in many ways.

The fundamental role of pH in the anthocyanins chemical behavior and in their extractability during winemaking

The chemical behavior of anthocyanins is considerably affected even by slight pH variations with impor-tant implications for the winemaking as well as for the wine conservation

Relations entre critères sensoriels et analytiques des vins et des vendanges de Cabernet franc issus de terroirs et de millésimes différents en Val de Loire. Essai de caractérisation de la typicité

En France, la notion de Terroir a largement contribué à la réputation de nombreux vignobles. Elle a permis aussi d’accentuer la sensibilité des consommateurs, à la notion d’origine d’un produit. L’avenir de nombreux vignobles français semble lié à la capacité à innover en produisant des vins de qualité possédant en plus une typicité, aspect sensoriel susceptible de s’affirmer comme un facteur de vente auprès des futurs clients éduqués sur le plan du goût.

Swiss program for the creation of fungal disease resistant grape varieties in Switzerland

Grapevine breeding is part of the research program of Agroscope in Switzerland since 1965. From 1965 to 1995, the aim of the Vitis vinifera crosses was to obtain a high resistance to grey rot (Botrytis cinerea), one of the most virulent fungal pathogens in the Swiss vineyard. In 2021, the grape varieties released from this first breeding program covered 936 ha of the 15’000 ha of the Swiss vineyard.
In 1996, a second breeding program aimed at obtaining, by classical interspecific hybridization, grape varieties resistant to downy mildew (Plasmopara viticola) and powdery mildew (Erisyphe necator) and less sensitive to grey rot (Botrytis cinerea). In order to accelerate and make the selection process more reliable, an early biochemical test was developed based on the natural defense mechanisms of the vine against downy mildew (stilbene phytoalexins). The synthesis of stilbenes (i.e., resveratrol and its oxidized dimers - and -viniférine) and pterostilbenes (methylated derivative) is among the most efficient induced defense mechanisms of grapevine against fungal pathogens on both the leaves and the clusters.
