Reasoning a Terroir policy on the basis of the prospective study of the French wine sector

Abstract

The prospective study of the French wine sector (Sebillotte et al., 2004) has identified “groups of micro-scenarios” at the end of the analysis of the characteristics of this wine sector. These groups, which have been defined from correlations between ‘structural’ variables, are activated by ‘driving’ variables, which are supposed either to be active or not, define different pertinent micro-scenarios (MSc) of events which may reasonably occurr. Three of those groups are directly related to the production and the management of Terroir wines. 

References

These groups of micro-scenarios are: 
1) MSc2 group “Wine productions and funds market” which leads to 4 MSc: 
– “The New Viticultural World declines” 
– “Coexistence with terroir wines and industrial blended wines” 
– “The industrial blendings without Geographical Indication” 
– “The geographical Indication as a strategy for the New Viticultural World” 
2) MSc5 group “The quality marks of wine” which leads to 4 MSc: 
– “Aroma-enriched wines for wine bars” 
– “The consumption occasion as a quality mark” 
– “ ’Terra vitis’, aromas and environment” 
– “A vintage table wine which is marked ‘Veritas’ “ 
3) MSc8 group “ ‘AOC’, technical evolutions and labelling”: 
– “The AOC and the VQPRD refuse GMO which are accepted worldwide” 
– “The AOC integrates the technical evolutions without any limit” 
– “The GMO are little used, and marked according to bilateral agreements” 
– “In a viticultural world without GMO, the French AOC system is in question”. 
These diferrent events or MSc are analyzed through the various elements which are included in the Terroir concept, in order to estimate the direct practical implications into vineyards, and the adaptation or evolution ability of vineyards as well

The effect of Nitrogen and Sulphur foliar applications in hot climates

ine nitrogen deficiency can negatively influence the aroma profile and ageing potential of white wines. Canopy management can alter vine microclimate, affect the nitrogen availability and influence the response of leaf senescence. Increasing the nitrogen availability to vines can increase the Yeast Assimilable Nitrogen (YAN) levels in harvested fruit and wine. Studies show that foliar nitrogen and sulphur applications at véraison, on low YAN Sauvignon blanc grapes have an effect on the level of amino acids (Jreij et al. 2009) and on S-containing compounds such as glutathione and thiols (Lacroux et al. 2008), which in turn can influence the formation of major volatiles and the aroma profile of the wine.

Modelling grape and wine quality through PLS Spline statistical method

Started in 1994, this project intends to explain quality of grapes and wines using data of soil, climate and vineyard that are currently used in field trials.

Discovering the process of noble rot: fungal ecology of grape berries during the noble rot transformation in different vineyards of the Tokaj wine region

Botrytis cinerea, a well-known grapevine pathogen, has more than 1200 host plants causing grey rot in grapevine berries. However, it can also result in a desirable phenomenon called noble rot under specific microclimate conditions. An extraordinary demonstration of this natural process can be observed in the creation of aszú wines within Hungary’s Tokaj wine region. Beside B. cinerea other fungi and yeasts are involved in the secondary metabolic development of the grape berry which contributes to the sensory and analytical characterization of noble rot wines.

Soil electrical resistivity, a new and revealing technique for precision viticulture

High resolution spatial information of soil electrical resistivity (ER) was gathered to assess the spatial variability patterns of vegetative growth of two commercial vineyards (Vitis vinifera L. cv.

Service crop effects on grapevine water and nitrogen status and yield under Mediterranean climate

Service crops in vineyard can provide multiple ecosystem services but they can also lead to competition with the grapevine for soil resources in the Mediterranean region due to potential severe droughts (Garcia et al., 2018). One of the levers of action to manage this competition is the choice of species adapted in terms of growth dynamics and water and nutrients’ needs. The objectives of this study were to determine the effect of temporary service crops on grapevine water and nitrogen status and grapevine yield and yield components in a Mediterranean vineyard.
