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.

The influence of terroir on the quality of wine of the Cahors A.O.C

Dans le but d’améliorer la qualité et la typicité des vins de l’Appellation d’0rigine Contrôlée CAHORS, une étude a été réalisée afin de mettre en évidence l’adéquation Cépage-Terroir- Qualité du vin.
Selon la méthodologie proposée par MORLAT et ASSELIN (1992), neuf unités terroirs ont été déterminées. Sur chacune, des parcelles de référence homogènes quant au matériel végétal Cot ou Malbec ( cépage principal de cette appellation greffé sur S04, et aux méthodes culturales, ont été suivies au niveau agronomique et œnologique (GARCIA et al., 1996).

Impact of yeast strain and aging time on the secondary metabolites, macromolecule composition, and sensory attributes of sparkling wines elaborated by the traditional method

The occurrence of aroma and macromolecule constituents in sparkling wines, directly influencing their organoleptic characteristics, is affected by several factors, including the grape cultivar, base-wine particularities, inoculated yeasts, the aging time, and winemaking practices [1].

Characteristics of ecological production of grape and wine in Prizren’s vineyard territory in Yugoslavia

Prizren’s vineyard territory-y assigned for ecological production of grapes and wine includes 1. 200 hectares of vineyard located in five separate localities which belongs to the P KB “Kosovo vina”, Mala Krusa in Prizren. Division of vineyard territory in zones was carried out in 1974. Pertaining to the vineyards, the climate and soil conditions have been studied and determined as well as topographie establishing of vineyard boundaries.

THE IMPACT OF NON-SACCHAROMYCES YEASTS ON THE WHITE WINE QUALITY

Selected strains of non-Saccharomyces yeasts showed a positive effect on sensory characteristics and aromatic complexity of wine. A sequential microbial culture of non-Saccharomyces and S. cerevisiae species is usually inoculated due to poorer fermentability of non-Saccharomyces species. The aim of the study was to investigate the role of non-Saccharomyces yeasts in the production of white wines. We evaluated how individual combinations of sequential inoculations of non-Saccharomyces and S. cerevisiae species affect the aromatic compounds (volatile thiols and esters) and sensory characteristics of the wines.
