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.

Comparison between the volatile chemical profile of two different blends for PDO “Valpolicella Superiore”

Valpolicella is a famous wine producing region located in the north of Verona close to Garda lake and owes its fame above all to the production of two Protected Designation of Origins (PDOs) withered wines: Amarone and Recioto. Nowadays the production of another PDO, Valpolicella Superiore is gaining more attention by the consumers, increasing the interest of the wineries to improve the quality of this wines

Genotype-environment interaction of three cultivars of vitis vinifera L. cultivated in two different environments of the Ischia island: effect on production and quality; aspects of the quality of the obtained wines

Pendant une période de trois années le comportement productif et qualitatif de trois cépages tous indigènes de la région de Campania (Italie méridionale) dans deux terroirs de l’île d’Ischia a été étudié; ceci pour obtenir quelques indications préliminaires sur le comportement productif et qualitatif des cépages et sur la qualité des vins.

Use of artificial intelligence for the prediction of microbial diseases of grapevine and optimisation of fungicide application

Plasmopara viticola, the causal agent of downy mildew (DM), and Uncinula necator, the causal agent of powdery mildew (PM), are two of the main phytopathogenic microorganisms causing major economic losses in the primary sector, especially in the wine sector, by wilting bunches and leaves with a consequent decrease in the photosynthetic rate of the plant and in the annual yield. Currently, the most widespread methods for planning spraying are based on the 3-10 rule, which states that the first application should take place when: (i) the air temperature is greater than 10°C; (ii) shoots are equal or greater than 10 cm; and (iii) a minimum of 10 mm rainfall within 24–48 hours has occurred, or at the beginning of the bud break with periodic applications according to the manufacturer’s instructions.

Application of high power ultrasounds during red wine vinification

Wine color is one of the main organoleptic characteristics influencing its quality. It is of especial interest in red vinifications due to the economic resources that wineries have to invest for the extraction of the phenolic compounds responsible of wine color, compounds that are mainly located inside the skin cell vacuoles. Moreover, these phenolic compounds not only influence color but also other organoleptic properties such as body, mouthfeel, astringency and flavour. The transference of phenolic compounds from grapes to must during vinification is closely related with the type of grapes and the winemaking technique.
