Grapevine performances in five areas of ‘Chianti Classico’ Comportement de la vigne en cinq zones des « Chianti Classico »

Abstract

The research was carried out in the ‘Chianti Classico’ area and it was part of the ‘Chianti Classico 2000’ research project. The performances ‘Sangiovese’ grapevine (clone ‘SSF-A548’) grafted on ‘1103P’ and ‘420A’ rootstocks, were evaluated during a six years period, on five experimental vineyards located in the Province of Florence and Siena. The vineyards were established at a density of 3500 plants per hectare, trained to horizontal spur cordon (m 0.7 from the ground) with 30000 buds per hectare. The main meteorological data were monitored by automatic stations and soil analysis was performed at the beginning of the trials. Vines were planted in a randomized block design with four or five replication according to the vineyard size and uniformity. During six consecutive years on 30 plants from each thesis were carried out the following observations: phenology earliness (budbreak, veraison), bud fertility, bunch weight, and yield and pruning weight per plant, must characteristics of the berries at harvest. Physical and chemical analysis of wines obtained from microvinification (made in 500 L containers), were also performed. The climatic differences resulted among the zones of the ‘Chianti Classico’ examined, had a significant effect on vine phenology also in relationship with altitude, which together to soil characteristics contributed to affect the agronomic behaviour of the three varieties, the must composition and the wine characteristics. Discriminant analysis allowed distinguishing some sites, whose differences can be ascribed to the territorial influence on the vegetative and productive activity of the grapevine, berry ripening and wine composition. Hierarchical influences due to clone ‘SSF-A548’ according to the site and year are presented.

Effects of major enological variables on the evolution of the chemical profile in Schiava over the vinification: an experimental design approach

Schiava cv. (germ. Vernatsch) is a group of grape varieties used for winemaking (e.g. Kleinvernatsch-Schiava gentile, Grauvernatsch-Schiava grigia, Edelvernatsch-Schiava grossa) historically reported in Northern Italy, Austria, Germany and Croatia. Beside common phenotypic traits, these varieties have been also hypothesized to share a common geographical origin in Slavonia (Eastern Croatia). Nowadays, Schiava cv. are considered historical grape varieties of northern regions of Italy such as Lombardy, Trentino and South Tyrol. Traditionally widely consumed locally and also exported, over the past decades there has been a steady drop in production of these grapes, although with a parallel increase in wine quality. In this report, the effects of three main enological variables on the chemical components of Schiava produced in South Tyrol (var. Schiava grossa) are investigated from grape to bottle.

MONOSACCHARIDE COMPOSITION AND POLYSACCHARIDE FAMILIES OF LYOPHILISED EXTRACTS OBTAINED FROM POMACES OF DIFFERENT WHITE GRAPE VARIETIES

The recovery of bioactive compounds from grape and wine by-products is currently an important and necessary objective for sustainability. Grape pomace is one of the main by-products and is a rich source of some bioactive compounds such as polyphenols, polysaccharides, fatty acids, minerals and seed oil. Polysaccharides contained in the grape cell wall can be rhamnogalacturonans type II (RG-II), polysaccharides rich in arabinose and galactose (PRAG), mannoproteins (MP), homogalacturonans (HG) and non pectic polysaccharides (NPP).
