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.

Vintage influence on Grenache N, Syrah N and Mourvedre N in Côtes du Rhône (France)

Vintage is part of « terroir ». The aim of this work is to study, through vine and berry parameters, the effect of vintage on the three major red grape varieties in Côtes du Rhône : Grenache N, Syrah N and Mourvedre N. We first characterized vintages 1997 to 2003, highlighting similar features in grape development across the different cultivars since 2001 only.

Sustainability is a key focus in viticulture, where managing abiotic and biotic stress presents a major challenge.

Remote sensing applications in viticulture: recent advances and new opportunities

Remote sensing applications in viticulture have been a research theme now for nearly two decades, becoming a valuable tool for vineyard management. Metrics produced using remotely sensed images of vineyards have yielded relationships with grape quality and yield that can help optimise vineyard performance

Influence of processing parameters on aroma profile of conventional and ecological Cabernet-Sauvignon red wine during concentration by reverse osmosis

Wine aroma represents one of the most important quality parameter and it is influenced by various factors (viticulture and vinification techniques, climate or storage conditions etc.). Wines produced from conventionally and ecologically grown grapes of same variety have different chemical composition and aroma profile [1]. Aroma profile of wine can be also influenced by additional treatment of wine, such as concentration of wine by reverse osmosis (RO). Reverse osmosis represents a pressure-driven membrane separation technique that separates the initial wine on the retentate or concentrate that is retained on the membrane, and permeate that passes through it [2]. Wine permeate usually containes water, ethanol, acetic acid and several low molecular weight compounds that can pass through the membrane. This property enables the use of reverse osmosis membranes for wine concentration, partial dealcoholization, acetic acid or aroma correction [3,4].
