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.

Some applications come from a method to concentrate proteins

All techniques usually used to assay proteins was not reliable in vegetable extract due to interferences with the components included in extracts like polyphenols, tanins, pectines, aromatics compounds. Absorbance at 280nm, Kjeldhal assay, Biuret and Lowry methods, Acid Bicinchonique technique and Bradford assay give the results depending on the composition of extract, on the presence or not of detergent and on the raw material (Marchal, 1995). Another difficulty in these extracts for the quantification of proteins comes from the large amount of water included in vegetable and the low concentration of proteins. Thus in red wines, proteins are usually not taken into account due to their low concentration (typically below 10 mgL-1) and to the presence of anthocyanis and polyphenols.

Effect Of Grape Polysaccharides On The Volatile Composition Of Red Wines

Yeast mannoproteins and derivates are polysaccharides produced from the cell walls of different yeast strains widely used in the winemaking and finning of wines to improve their overall stability and sensory properties.

Quantification of Eugenol in various matrixes from hybrids vines. Case study of Armagnac white spirits production

Nowadays, winemaking is dealing with great challenges, notably climate change, disease resistance and low pesticide inputs, desire for more sustainable agricultural productions and permanent changing of consumer preference.

The role and quantification of vitamins in wine: what do we know?

AIM: Vitamins are essential compounds to numerous organisms, including yeasts, and appear highly significant during winemaking processes.

Evaluation of the effects of pruning methodology on the development of young vines 

Grapevine pruning is one of the most important practices in the vineyards. Winegrowers use it to provide the vines the shape needed, or to maintain it once achieved, and also to balance vegetative growth and fruit production. In the last decades, careless pruning has been blamed, among other factors, as responsible of the vineyard decay that is been observed even in young vines. However, to our knowledge, there is a lack of systematic research trying to elucidate to which extent the pruning method used affects plant development or its susceptibility to grapevine trunk diseases (GTD). Within this context, the aim of this work is to study the influence of different pruning method strategies on the development of field-planted young vines.
