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.

The sea breeze: a significant climatic factor for viticultural zoning in coastal wine growing areas

La brise de mer est un facteur climatique important pour le zonage viticole des régions viticoles côtières car l’accélération du vent qui lui est associée l’après midi ainsi que l’augmentation de l’humidité relative et la réduction de la température concomitantes sont significatives pour le fonctionnement de la vigne et, par conséquent, la qualité du raisin et du vin

Vineyard floor management intensity impacts soil health indicators and biodiversity across South Australian viticultural landscapes

Vineyard floors in warm, dry landscapes including those in South Australia, have traditionally been managed using intensive practices such as tillage and herbicides to control weeds and vegetation, thereby limiting competition with grapevines for water and nutrients in order to not compromise yields.

Mannoprotein extracts from wine lees: characterization and impact on wine properties

This study aims at exploiting an undervalued winemaking by-product, wine yeast lees, by developing efficient and food-grade methods for the extraction of yeast glycoproteins. These extracts were then supplemented to wine and their impact on wine properties assessed.

Polyphenolic profile and dietary fiber content of skins and seeds from unfermented and fermented grape pomace

The valorization of winemaking byproducts is subordinated to the knowledge of their chemical characteristics. This work concerned the determination of the polyphenolic profile and the dietary fiber content of skins and seeds from unfermented and fermented pomace of different cultivars (Moscato bianco, Cortese, Arneis, Pinot Noir, Barbera, Grignolino, Nebbiolo), sampled from some wineries in the Piedmont area (Italy) during the 2020 harvest.

Low and zero alcohol “wines”: impact of different dealcoholization processes on phenol profile and health benefits

Consumers’ demand for non-alcoholic wine has notably increased in the last years: this trend is a consequence of a growing interest in more healthy habits, and as a response to higher alcohol levels in wine due to climate change. In addition, drinking limitations due to physiological/pathological conditions (e.g., pregnancy, diabetes, hepatic disorders), driving regulations, ethical/religious considerations, and high import taxes on alcoholic beverages have positively influenced this marked (us$ 1.6 billion in 2021). International organisation of vine and wine (OIV) established that alcohol content defining wines must not be less than 8.5% vol, (OIV, 2017).
