“Terroir” and climate change in Franconia / Germany

Abstract

Franconia which is a “cool climate” winegrowing region is well known for its fruity white wines. The most common grape cultivars are Silvaner and Mueller-Thurgau.
Franconia is a landscape of contrasts with various climatic conditions. The vineyard sites are located at a height between 120 m and 420 m above sea level on slopes and steep slopes as well as on terraces.
In favourable south orientated sites the maximum temperatures reach about 40° C (peak value year 2003), while winter frosts cause deep temperatures down to about -27°C (year 2002) in valleys or exposed sites.
At present, the Franconian winegrowing region is being affected by the global climate change. Several forecasts predict an average annual temperature increase of approximately 2°C for Southern Germany until the year 2050. During the same period an increased occurrence of temperature-related extreme events is expected.
In case of permanent increase of the average air temperatures and temperature-related extreme events, the cultivation of grapes on E, W and NW slopes could be considered appropriate to preserve the fruity character of traditional white wines.

Méthode et outils de valorisation des terroirs en cave coopérative

Depuis le début des années 90, les vignerons des Caves Coopératives de l’Appellation “Côtes du Rhône” se sont penchés, au sein des structures de réflexion du Syndicat Général, sur deux axes de réflexion:
– Détermination des critères de sélection et de rémunération différenciée des apports de vendange;
– Organisation des sélections de vendanges sur la base des terroirs afin d’augmenter quantitativement le potentiel de sélection au sein de l’unité de production.

Analyse et modélisation des transferts thermiques dans un sol de vignoble. Effets des techniques culturales

Natural factors such as the environment in which the vine is grown play an important role in the quality of the wine. If you want to produce a good wine, it is indeed essential to produce quality grapes. To do this, we must enhance and optimize the terroir effect which, for the moment, plays a role that is not very well known. It is therefore essential, for example, to have scientifically established and well quantifiable relationships in order to have the system of areas of controlled origin accepted. R. Morlat (1989) and G. Seguin (1970) have already carried out studies on the role of certain soil factors on grape quality. In particular, they showed the importance of soil temperature and water content.

Biotic and abiotic factors affecting physiological aspects underlying vegetative vigour in two commercial grapevine varieties

Grapevine vigour, defined as the propensity to assimilate, store and/or use non-structural sugars for allowing fast growth of shoots and producing large canopies[1], is crucial to optimize vineyard management. Recently, a model has been proposed for predicting the vigor of young grapevines through the measurement of the vegetative growth and physiological parameters, such as water status and gas exchange[2]. Our objectives were (1) to explore the influence of the association of two grapevine varieties (Tempranillo and Cabernet Sauvignon, grafted onto R110 rootstocks) with arbuscular mycorrhizal fungi (AMF) on the vegetative vigour of young plants; and (2) to assess the effect of environmental factors linked to climate change on the vegetative vigour of Cabernet Sauvignon.
