Campania region grapevine patrimony: a determination of the heat requirement of 19 nearly all-native ultivars. Nine years of observations.

Abstract

[English version below]

Nous avons peu d’informations sur les cépages cultivés dans la région de la Campania (sud de l’ltalie). En particulier insuffisant sont les études sur les besoins thermiques de tels cépages. Les études sur les besoins thermiques des cépages peuvent contribuer au positionnement correct des cultivars dans les zones capables d’optimiser le rapport génotype-environnement des cépages du quel dépend, l’expression qualitative de la production. Pour les dites motivations nous avons effectué la présente étude, dans laquelle nous avons déterminé les conditions thermiques de 19 cépages presque tous indigènes de la Région, ayant comme référence le modèle proposé par AMERINE et WINKLER (1944). L’étude qui a déterminé une exigence de la chaleur des variétés étudies variables de 1625 degré-jours ( cv Fiano) a 2011 degré-jours (Bianca Zita), ajoute une autre étape à la connaissance du patrimoine viticole de la Campania.

 

There is little information on the grapevines cultivated in the Campania region (south of ltaly). In particular insufficient are the studies on the thermal requirements of such grapevines. Trials on the thermal needs of the grapevines may contribute to the correct positioning of the cultivars in areas able to optimise the environment genotype ratio of a cultivar on which, qualitative expression of the production depends. For said motivations it has been set up the present study, in which it was determined the thermal requirements of 19 cultivars nearly all native of the Region, having like reference the model proposed by AMERINE and WINKLER (1944). The study that evidenced an heat requirement of the studied cultivars variable from 1625 degree-days (cv Fiano) to 2011 degree-days (Bianca Zita), adds an other step to the acquaintance of the Campania grapevine patrimony.

A climatic characterisation of the sub-Appellations in the Niagara Peninsula wine region

This study used climatic and topographic data to characterize the sub-appellations that have been recently delineated in the Niagara Peninsula viticulture area in order to assess their potential for ripening early to late season Vitis vinifera varieties. No major differences were found in the ripening-period mean temperatures, but major differences in the diurnal temperature ranges were observed.

Prediction of sauvignon blanc quality gradings with static headspace−gas chromatography−ion mobility spectrometry (SHS−GC−IMS) and machine learning

The main goal of the current study is the development of a cost-effective and easy-to-use method suitable for use in the laboratory of commercial wineries to analyze wine aroma. Additionally, this study attempted to establish a prediction model for wine quality gradings based on their aroma, which could reveal the important aroma compounds that correlate well with different grades of perceived quality METHODS: Parameters of the SHS−GC−IMS instrument were first optimized to acquire the most desirable chromatographic resolution and signal intensities. Method stability was then exhibited by repeatability and reproducibility. Subsequently, compound identification was conducted. After method development, a total of 143 end-ferment wine samples of three different quality gradings from vintage 2020 were analyzed with the SHS−GC−IMS instrument. Six machine learning methods were employed to process the results and construct a quality prediction model. Techniques that aim to explain the model to extract useful insights were also applied.

Enological and nutraceutical potential of some grape varieties tolerant to downy mildew and powdery mildew

AIM: Since 2012 the Veneto Region regulation (north-east Italy) allowed wine production using 20 hybrid grapevine varieties selected for their high tolerance to downy mildew and powdery mildew. Characterized by vigour, high grape productivity and low pesticide use, these varieties are suitable to develop sustainable viticulture in mountain areas located at medium altitudes.

The use of plasma activated water in barrel disinfection: impact on oak wood composition

The use of barrels is a practice that improves the quality of wines. The porous structure of wood favors the accumulation of microorganisms that can deteriorate the quality of wines so that barrel cleaning and sanitizing treatments are essential. The burning of sulphur discs has been the most common practice in winemaking because ots biocide effect. Nevertheless, its effectiveness is still insufficient and it is harmful for human health.
