Territoires et zones viticoles. Aspects climatiques, pédologiques, agronomiques. Caractérisation des terroirs viticoles: une étude systémique

Abstract

On assiste actuellement à l’émergence d’une demande sociale forte à l’égard de fonctions par ailleurs traditionnelles de l’agriculture, qui concernent la gestion des ressources du milieu, le maintien d’un tissu social rural, la valorisation des territoires ruraux et l’entretien des paysages.
L’intérét suscité amène à préciser comment se pose aujourd’hui à la recherche, la question de la gestion des territoires ruraux. En effet, les impératifs de la production agricole, les phénomènes de déprise et les directives européennes et mondiales relatives à la protection de l’environnement, conduisent à analyser précisément le métier et la fonction d’agriculteur et du vigneron en l’occurrence.
Je pense que les conclusions d’un tel colloque feront non seulement émettre une réflexion, mais surtout apporteront des éléments de réponse, pour une prise en compte réelle de la gestion des territoires (ce qui nécessite bien entendu des méthodologies de délimitation ou de zonage).
La diversité des champs disciplinaires concernés, des méthodologies mises en oeuvre, des partenaires impliqués, montre bien l’ampleur et la complexité d’une réflexion à laquelle souhaitent s’associer les acteurs de développement local, les décideurs, les professionnels de l’agriculture, de la viticulture et des structures de transformation, mais aussi plus largement les consommateurs.
La qualité s’élabore tout au long d’un processus. Ceci sollicite des compétences variées en agronomie, en création variétale, en technologie … Une telle approche de la qualité des produits peut constituer un principe fédérateur puissant, dans un contexte où le pilotage de la consommation par l’aval en fait un élément déterminant de la compétitivité des filières et de leur diversification.

Evaluation of the enological potential of red grapes in southern Brazil

The Campanha Gaúcha is located in the pampa biome and has unique characteristics, as it is the hottest producing region with the lowest volume of rain in Southern Brazil. Furthermore, the large extensions of flat or low-sloping areas, harsh winters and great sunshine during the ripening period, made this the second largest producer of fine wines in Brazil.

Usefulness and limits of the crop water stress index obtained from leaf temperature for vine water status monitoring

Aims: This work aimed i) to calibrate the accuracy of estimating vineyard water status by crop water stress index (CWSI) compared to stem water potential; ii) to determine the time interval during the day that best correlates to stem water potential and iii) to understand the its usefulness.

Experimental vinification of withered grapes of Vitis vinifera “Muscat of Alexandria”

The objective of the present work is to investigate wine produced from dehydrated grapes and vinified according to classical Roman manuals.

METHODS – Locally produced Muscat of Alexandria’s grapes were used for the sweet wine production, grown in the experimental vineyard of Instituto Superior de Agronomia (Lisbon, Portugal). The grapes were harvested manually slightly over-ripe and subjected to greenhouse drying. After 7-10 days dried grapes were transported to an experimental winery for various operations (e.g., grape weighing, sorting, crushing/destemming). Several maceration protocols were used comprising the addition of saltwater and white wine to whole bunches or destemmed grapes. Fermentation was conducted with the addition of commercial yeast. The standard physico-chemical parameters of wines were determined according to the OIV standards.

WINE FERMENTATION METABOLITES PRODUCED BY TWO TORULASPORA DELBRUECKII STRAINS ISOLATED FROM OKANAGAN VALLEY, BC, CANADA VINEYARDS

Wine aroma is influenced by various factors, from agricultural practices in the vineyard to the enological choices made by winemakers throughout the vinification process. Spontaneous fermentations have a characteristically deeper complexity of aromas when compared to fermentations that have been inoculated with Saccharomyces (S.) cerevisiae because of the diversity of microflora naturally present on grape skins. Non-Saccharomyces yeast are being extensively studied for their ability to positively contribute to wine aroma and flavour. These yeasts are known to liberate more bound volatile compounds present in grape must than S. cerevisiae through the enzymatic action of β-glucosidases and β-lyases1.

Innovation in pre- and post-harvest biocontrol: novel strategies against Botrytis cinerea for grape preservation

Driven by the demand for sustainable agriculture, biocontrol is emerging as a crucial alternative to chemical fungicides for crop protection.
