Study of the sensory dimension of the wine typicality related to a terroir and crossing with their viticultural and oenological characteristics

Abstract

The typicality of a product can be characterized by properties of similarity in relation to a type, but also by the properties of distinction. The typicality related to the soil is associated with a delimited geographical origin, and with asserted characteristics. The aim of this study is to determine the sensory profile of typical wines and to interrelate with their technical characteristics. A quantitative descriptive analysis was carried out by an expert panel on 34 wines from Vintage 2005 (23 “Anjou-Villages Brissac” and 11 “outsiders”). All these wines came from plots being able to product the A.O.C. “Anjou-Villages Brissac”. In addition, a characterization of the typicality of the products was carried out with “just about right” profiles, by a group of professionals of this area, from descriptors raised by discussion with all the producers of the area. Finally, a crossing of the sensory data with viticultural and enological practices was carried out.
The results showed the relevance of the expert panel in the discrimination of the products. Two groups could be distinguished, one consisted essentially of wines “Anjou-Villages Brissac” and the other consisted essentially of wines “outsiders”. The panel of professionals proved to be relevant on the characterization of the total quality of the wines, but did not appear consensual for more precise descriptors. The crossing of sensory profiles with some technical acts showed significant effects of “thinning out of leaves”, “disbudding”, “maceration” and “fermentation with industrial yeast” on sensory characteristics.

The evolution of the concept of geographical denomination in South America

Vers la fin du XX siècle, la vitiviniculture argentine a subi une profonde transformation qualitative atteignant toute la filière. L’analyse de l’évolution de la superficie des vignobles, l’élaboration des vins, la consommation et les exportations, permet de mettre en évidence ces changements. Dans ce contexte, l’origine apparaît comme un outil de force, d’expansion et de succès sur les marchés.

Variability of Tempranillo phenology within the toro do (Spain) and its relationship to climatic characteristics

Aims: The objective of this research was to analyse the spatial and temporal variability of vine phenology of the Tempranillo variety in the Toro Designation of Origen (DO) related to climatic conditions at present and under future climate change scenarios.

The use of cation exchange resins for wine acidity adjustment: Optimization of the process and the effects on tartrate formation and oxidative stability

Acidity adjustments are key to microbial control, sensory quality and wine longevity. Acidification with cation exchange resins -in acid cycle- offers the possibility to reduce the pH by exchanging wine cations, such as potassium (K+), for hydrogen ions (H+). During the exchange process, the removal of potassium and calcium ions contributes to limiting the formation of tartrate salts, thus offering an alternative solution to conventional methods for tartrate stability. Moreover, the reduction of wine pH and the removal of metals catalyzers (e.g. iron) could positively impact the wine’s oxidative stability. Therefore, the aims of this work were (a) to optimize the ion exchange process by testing different volumes and concentrations of sulfuric acid (H2SO4) during the acid cycle, (b) evaluate the effects of the ion exchange process on the formation of tartrate salts, and (c) analyze the oxidative stability of the treated wines.

Cultivation forms and viticulture models adapting to adverse “environmental” conditions

One of the main problems in viticultural production in Istria (Croatia) is a labour shortage in periods of intensive works, mainly during summer, respectively during tourist season.
