Characterization of Mesoclimatic zones competent for the culture of vine (vitis vinifera l.) in the province of San Juan, Argentina

Abstract

Le zonage agroclimatique a pour objet de caractériser des lieux ayant des aptitudes distinctes pour la production de la vigne. La province de San Juan en Argentine est l’une des régions vitivinicoles les plus chaudes du pays. Cette étude a pour but de déterminer les zones aptes à la culture de la vigne, en se basant sur l’analyse du mésoclimat de cette province, et de définir l’aptitude viticole de ces zones et leur délimitation géographique.
Des indices écologiques sont calculés sur de longues séries de données, provenant d’un réseau de stations météorologiques. La comparaison de ces indices a permis de sélectionner les plus représentatifs et de grouper les mésoclimats similaires.
Dans la province de San Juan, six zones climatiques ont été définies, caractérisant le comportement de la vigne selon le type mésoclimatique. L’intégrale thermique de base 13°C et l’indice des températures minimales du mois avant récolte dans cette région chaude sont les variables principales qui permettent ce zonage.

The aim of an agroclimatic zoning is to characterize areas, which have different capacities for the vine growing production. The Province of San Juan is the hottest grapes and wines producing region of Argentine. This study aims at determine the zones in the province which are competent for the vineyards thanks to analysis of microclimate, and to define their agricultural and enological potential.
Ecological indices coming from databases of meteorological stations have been calculated. The comparison among these indices allowed to select the most representative of them and to gather similar mesoclimates.
In the Province of San Juan, six climatic zones have been characterized, each of them corresponding to a specific vine behaviour. This zoning has been made thanks to two main indices: the thermic integral basis 13°C and the indices of minimal temperature during the month before harvesting.

Impact of sulfur compounds to the antioxidant stability of white wines

The chemical mechanisms involved in oxidation/reduction potential of wine during winemaking and aging are affecting its color, aroma and taste. Chemical oxidation is one of the major causes of development of off-flavors during ageing1. Thus, the chemical changes in wine during storage should be controlled to ensure the sensory quality of the product and avoid consumer rejection that will compromise the economic value of the product. The 1-hydroxyethyl radical has been recognized as the key radical intermediate in the oxidative reactions in wine2. Based on the kinetic study of POBN-1-hydroxyethyl spin adduct formation in wines initiated via the Fenton reaction, a novel tool was recently developed in our laboratory to quantify the resistance of wines against oxidation3.

Overall conceptual characterization of aged dry white wines using a mental descriptive questionnaire

The purpose of the present study was to understand the overall concept of an aged dry white wine using a descriptive mental questionnaire. A total of 680 worldwide participants, grouped according to their involvement in the wine business, replied to an online questionnaire to characterize the sensory analytical and synthetic descriptors of an aged dry white wine. The descriptors were selected using a Check-All-That-Apply (CATA) approach concerning wine colour, aroma, taste, mouthfeel, and global appreciation.
