The« Sigales’ method »

Abstract

Le comportement de la vigne est étroitement lié aux propriétés hydriques des sols surtout dans leurs parties profondes. Cette importance majeure des variables les moins accessibles à l’observation rend difficile la réalisation de cartes de sols pertinentes.
Connaissance et expérience du vigneron sont extrêmement riches d’informations.
C’est pourquoi il est placé au cœur de la réflexion, de façon à ce que les compétences scientifiques et techniques des experts et les observations pratiques des hommes de terrain s’enrichissent mutuellement.
Cette « méthode » est basée sur un système de réunions, de formation, qui permet une validation systématique en salle et sur le terrain des hypothèses de spatialisation cartographique.
Ainsi, avec des moyens raisonnables, deux buts sont atteints : la création de documents cartographiques validés et adaptés et la formation des vignerons, acteurs principaux de la filière viticole.

The behaviour of the grape plant is directly related to the availability of water in the deep and very deep ground layers. This major influence of the less accessible variables makes creation of relevant soil maps difficult.
The knowledge and the experience of the wine grower are the keys to gather meaningful information.
In the « Sigales’method » we try first to give sense to the observations of the wine growers and of their technical team by collective work. Then we draw more accurate maps that ve validate outside with them.
With affordable efforts we achieve two goals : validated and accepted maps and educated wine growers.

Three proximal sensors to estimate texture, skeleton and soil water storage in vineyards

Proximal sensors are becoming widely used in precision viticulture, due to the quick, easy and non-invasive identification of soil spatial variability. The apparent soil electrical conductivity (ECa) is the main parameter measured by sensors, which is correlated to many factors, like soil water content, salinity, clay content and mineralogy, rock fragments, bulk density, and porosity.

Climatic zoning of viticultural production periods over the year in the tropical zone: application of the methodology of the Géoviticulture MCC system

L’objectif de cette recherche est le zonage climatique des périodes viticoles de l’année dans la Vallée du São Francisco, région brésilienne productrice de vins située en climat tropical semi-aride. Dans cette région, la production peut être échelonnée sur tous les mois de l’année.

Understanding aroma loss during partial wine dealcoholization by vacuum distillation

Dealcoholization of wine has gained increasing attention as consumer preferences shift toward lower-alcohol or
alcohol-free beverages. This process meets key demands, including health-conscious lifestyles, regulatory
compliance, and the expanding non-alcoholic market [1-3].

Brettanomyces bruxellensis, born to live

The wine spoilage yeast Brettanomyces bruxellensis can be found at several steps in the winemaking process due to its resistance to multiple stress conditions. Among the resistance strategies, one could be the formation of biofilm, a lifestyle known to enhance persistence of microorganisms. In this study, we propose to characterize biofilm of B. bruxellensis in wine, especially through several microscopic analyses.

Effect of pre-fermentative strategies on the polysaccharide composition of must and white wines

Among the macromolecules of enological interest in white wines, much attention has been paid to polysaccharides.
