Présentation d’une méthodologie de caractérisation des terroirs et valorisation par l’étude de l’effet terroir sur la typicité et l’originalité du produit vin dans la région des Côtes du Rhône

Abstract

In the global economic context, an Appellation d’Origine Contrôlée must now more than ever control the typicity and originality of the wines it produces. It is in this spirit that the Côtes du Rhône have decided to acquire the means necessary for this control. As a preamble, it should be noted that as a professional entity, the Syndicat des Vignerons des Côtes du Rhône aims to develop a methodology for applying terroir studies to the promotion of the wine product. Thus, for all the purely fundamental aspects concerning the characterization of the terroirs, our wish is to surround ourselves with the competence of research partners, specialized in the matter.
Our own objective is to provide winegrowers with tools that allow them to better control the typicality of their product, by optimizing the development of the potential of their vineyard.

The methodology that we have developed to control the typicality of products through the terroir effect breaks down into three main components: – the characterization of the fundamental components of the nature of the terroirs,
– the study of the impact of the effect of the terroir on the physiology of the plant and especially on the typicity of the wine produced,
– the organization within the production units of all the elements of control and management of the viticultural parameters for the optimization of the oenological phase.

New methods and technologies to describe the environment in terroir studies

The concept of terroir in viticulture deals with the influence of environmental factors on vine behaviour and grape ripening. Recent advances in technology, in particular computer technology, allow a more in-depth study of the environment. Geomorphology can be studied with digital Elevation Models (DEM). Soils can be surveyed with geophysics.

Testing the effectiveness of Cell-Wall material from grape pomace as fining agent for red wines

Lately several works highlighted the capacity of grape cell-wall material (CWM) to interact with proanthocyanidins (PA), indicating its potential use as fining agent for red wines.1–4 However, those studies were performed by using purified PAs and very high doses of CWM (almost ten-fold higher than those used in wine industry for other commercial fining agents). The present study focuses on the applicability of CWM from Cabernet sauvignon pomace as fining agent for red wines under real winery conditions. Grapes of cultivar Cabernet sauvignon were harvested at three different maturity levels
(unripe, mature, and overripe) and used for red winemaking. The pomace of such vinifications were used as source of CWM, and applied into red wines at two different concentrations: 0.2 g/L and 2.5 g/L.

WINE RACKING IN THE WINERY AND THE USE OF INERT GASES: CONTROL AND OPTIMIZATION OF THE PROCESS

Atmospheric oxygen (O₂) generates oxidation in wines that affect their physicochemical and sensory evolution. The O₂ uptake in the different winemaking processes is generally considered to be negative for the sensory characteristics of white and rosé wines. Wine racking is a critical point of O₂ uptake, as the large surface area of the wine exposed during this operation and the inability to maintain an effective inert gas blanket over it.
The aim was to study the uptake of O₂ during the racking of a model wine as a reference and to compare with purging the destination tank with different inert gases.

Effect of two contrasting soils on grape and wine sensory characteristics in Shiraz

Aims: Berry composition and wine sensory characteristics reflect the origin of grape production and seasonal climatic conditions. The aim of this study was to compare berry and wine sensory characteristics from two contrasting soil types where the vineyard climate, geography, topography, vine and management factors were not different.
