Elaboration des cartes conseils pour une gestion du terroir à l’échelle parcellaire: utilisation d’algorithmes bases sur des paramètres physiques du milieu naturel

Abstract

The “Anjou Terroirs” programme aims at bringing the necessary scientific basis for a ratio­nal and reasoned exploitation of the technical itinerary of the terroir. The scale study is 1/12500. For the mapping, many parameters, such as the granulometry or the depth of soil are observed to each point of caracterisation. However, the composition and the quality of grapes do not depend directly on these parameters, but is influenced by variables such as water supply or vine precocity. These variables cannot be easily mapped, but can be esti­mated by algorithms based on expertise. The precision and the content of the cartographie study allow to quantify these main variables wich influence the vine behavior. It is therefore possible to build advisory maps that can be used by the vine growers at the scale of the par­cellary. As an example, a map on rootstock adaptation to the terroir has been published. Thanks to the knowledge obtained through a network of experimental plots, five fundamen­tal factors seems determinant to us, to choose a rootstock in Anjou condition: water sup­ply, natural drainage, iron chlorosis power of soil, vigour potential and precocity potential conferred by the terroir.

Classification and prediction of tannin botanical origin through voltammetry and machine learning approach

The classification of enological tannins has gained importance following the OIV’s requirement to include their botanical origin on product labels (OIV-OENO 624-2022).

Reviewing the geometry of terraces in the Douro region towards sustainable viticulture

The Douro demarcated region constitutes just over 50% of the area of mountain vineyard in the world, i.e., vineyards with slope gradients of 30% or above. Among the different (terraced) vineyard layouts, the formerly preferred wider terraces supporting two rows of vines and the currently advocated narrower single vine row, dominate the vineyards’ planting layout. The slope of these terraces, in other words, the supporting earth ramp, is a key element in these vineyards’ construction.

AGING PATTERNS OF VARIETAL VOLATILE PROFILES OF WHITE WINES: A CASE STUDY ON 18 ITALIAN VARIETAL WHITE WINES

During wine aging many compositional changes take place. In particular, aroma undergoes dramatic modifications through a wide range of reactions that to date are only partly understood. Italy owns one of the largest ampelographic heritages worldwide, with over three-hundred different varieties. Among these, many white grapes are employed for the production of dry still white wines. Some of these wines are consumed young while others are more prone to aging. For many of these wines, the aging patterns related to volatile composition are still unknown.

An innovative 21st century frost alert system for an age-old viticulture challenge

Damage during the budbreak period due to spring season frosts remains one of the most significant weather-related challenges to viticulture around the world. For example, in 2021, €2bn of estimated damage was reported in france while >50% of vineyards were badly affected in the UK in 2017.

Lean management to improve sustainability in wine sector: an exploratory study in the Prosecco DOC appellation

The contemporary wine sector confronts a formidable array of challenges, including burgeoning production costs and the constricted availability of natural resources. Heightened consumer awareness regarding sustainability issues further compounds these pressures, compelling companies to adopt more judicious resource utilization strategies. In response to these imperatives, there is a growing recognition of the need to overhaul production methodologies within the wine industry with a view to minimizing inputs and eliminating waste.
