La zonazione della valle d’Illasi (Verona)

Abstract

In the bottom of Val d’Illasi (Verona province), one of the major valleys which passes through the Lessini mountains, viticulture is widely extended. In the territory belonging to Illasi and Tregnago villages, which includes ca. 1100 ha of vineyards, devoted to produce Soave and Valpolicella DOC wines, an experimental survey was conducted on a network of twenty five reference vineyards. The area was characterized for soils, climate, viticulture and enological properties. The pedagogical survey carried out in the vineyards allowed to produce a soil map on a scale of 1:20.000 composed by 18 soil map units. In all the reference vineyards for three years (’93- ’95) grapevine phenology, yield, and vegetative growth were detected; during ripening maturation curves were monitored by juice composition. At vintage a sample of grape adequate for microvinification was collected. Wines were evaluated by sensorial analysis. The statistical data processing allowed to define 6 Land Suitability Units (2 for Soave and 4 for Valpolicella DOC), where vineyards resulted different in the vegetative and productive behavior, in the maturation patterns and in sensory properties of the wines. A satisfactory correlation among soil type x altitude interaction on phenology, vine potential yield and vegetative growth, grape and wine quality was able to explain the results, which were summarized in a Land Suitability map. Moreover, land characteristics and evaluation allowed to produce some Land Viticultural maps.

UNCOVERING THE ROLE OF BERRY MATURITY STAGE AND GRAPE GENOTYPE ON WINE CHARACTERISTICS: INSIGHTS FROM CHEMICAL CHARACTERISTICS AND VOLATILE COMPOUNDS ANALYSIS

In a climate change context and aiming for sustainable, high-quality Bordeaux wine production, this project examines the impact of grape maturity levels in various cultivars chosen for their adaptability, genetic diversity, and potential to enhance wine quality. The study explores the effects on wine compo-sition and quality through sensory and molecular methods. We studied eight 14-year-old Vitis vinifera cv. grape varieties from the same area (VITADAPT plots 1 and 5): Cabernet Franc, Cabernet Sauvignon, Carmenère, Castets, Cot, Merlot, Petit Verdot, and Touriga Nacional.

Multidisciplinary strategies for understanding ill-defined concepts

Aims: The objective of the present work is to review strategies applied to decrypt multidimensional and ill-defined concepts employed by winemakers and to illustrate these strategies with recent applications.

Effect of the plant sink/source balance on the chemical content of red table grapes (Vitis vinifera L.).

PPhloem transport of assimilates provides the materials needed for the growth and development of reproductive structures, storage and developing organs, and has long been recognized as a major determinant in crop yield.

Landscape study of the Suzette rural district. A vineyard in the heart of the Dentelles de Montmirail

Le territoire de Suzette se développe sur un grand coteau viticole et boisé situé au cœur du site naturel des Dentelles de Montmirail (40km au nord d’Avignon). Ce site est à la fois l’un des pôles d’attraction touristique du département et le lieu d’une production viticole renommée (Gigondas, Vacqueyras, Beaumes de Venise, … ). Cet ensemble remarquable de terrasses viticoles et de crêtes rocheuses et boisées, forme un des paysages emblématiques du Vaucluse. La commune est actuellement soumise à une importante pression foncière due à une forte demande résidentielle. Le paysage du coteau forme et possède de ce fait un patrimoine culturel de valeur et une image de marque importante pour la production viticole locale.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.
