Analyse de la perception du terroir et de sa valorisation par les viticulteurs de l’Anjou

Abstract

An integrated terroir characterization is currently realized in the French northern vineyard: “Anjou”. The concept of Basic Terroir Unit (B.T.U.) and its associated ground model “Rock, Alteration, Alterite” are used in this characterization. This work is coupled to a viticultural survey, based on parcels. These two approaches allow an analysis of the degree of perception of terroir and its valorization by vine growers. This analysis is realized at two scales: the ground model “Rock, Alteration, Alterite” applied in the whole study area and the B. T. U. for the both main geological systems: the metagrauwacke of the brioverian period and the green to grey sandstone schist of the ordovician-devonian period.
At the ground model scale, the vine growers have well differentiated the three environments by mesoclimatic (temperature of air, risk of frost), pedoclimatic (temperature and humidity of soil) and pedologic criteria. They have perceived also influences of the environment type on the behavior of the vine and integrated them in their viticultural and oenological practices. The analysis at B.T.U. scale, confirms the pertinence of the ground model “Rock, Alteration, Alterite” on the perception of pedoclimatic and pedologic characteristics and an important influence of the geological system on the mesoclimate of the parcel and on the vine behavior.

Terroir influence on growth, grapes and grenache wines in the AOC priorat, northeast Spain

The Mediterranean climate of The Priorat AOC, situated behind the coastal mountain range of Tarragona, tends towards continentality with very little precipitation during the vegetation cycle. The soil is poor, dry and rocky, largely composed of slate schist, known as “llicorella”. Vines primarily grow on steep slopes and terraces.

Anticipating consumer preference for low-alcohol wine: a machine learning analysis based on consumption habits and socio-demographics

The global wine consumption landscape is undergoing a transformation, marked by a growing trend towards reduced consumption and a preference for healthier lifestyles. In line with this shift, european union regulation (regulation eu 2021/2117) has recently redefined dealcoholized or partially dealcoholized wine within the wine category.

Selected ion flow tube mass spectrometry: a promising technology for the high throughput phenotyping of grape berry volatilome

Wine grapes breeding has been concentrating a lot of efforts within the grape research community over the last decade. The quick phenotyping of genotype quality traits including aroma composition remains challenging. Selected Ion Flow Tube Mass Spectrometry (SIFT-MS), a technology first available in 2008 and developing rapidly, could be particularly valuable for this usage. The aims of this study were i) to use SIFT-MS, to analyze the whole volatilome from different grape varieties, ii) to assess the ability of this technology to discriminate varieties according to their grape aroma composition, and iii) to study the stability of SIFT-MS signal over maturation to define a sampling strategy.
