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.

Monitoring of alcoholic fermentation: development of an applicable in-line system

Alcoholic fermentation plays a crucial role in the winemaking process. In addition to producing ethanol, it results in the formation of various secondary metabolites that significantly influence the wine’s characteristics.

Sensory study of potential kokumi compounds in wine 

Kokumi is a complex sensation perceived as enhanced palatability. Under the influence of kokumi substances, foods/beverages tastes become more flavorful with increased intensity, spread, continuity, richness, harmony, and punch which are the six related characteristics corresponding to the kokumi sensory concept (Yamamoto & Inui-Yamamoto 2023).

CHARACTERIZATION OF THE VOLATILE COMPOUNDS PROFILE OF COMMERCIAL GRAPPAS OBTAINED FROM THE POMACE OF AMARONE WINES

Grappa is a traditional Italian alcoholic beverage, with an alcohol content generally between 40-60% vol., obtained from the distillation of grape pomace used for the production of wine. Grappa are often aged in wooden barrels. There are various types of grappa: young, aromatic, aged, extra-aged depending on whether the distillate comes from aromatic vines or is aged in wooden barrels for shorter or longer periods. There is also flavored grappa if herbs, fruit or roots are added. All this makes it an extremely heterogeneous product both from an organoleptic and compositional point of view.

The influence of soil management practices on functional traits and biodiversity of weed communities in Swiss vineyards

Green cover in vine rows provides many ecological services, but can also negatively impact the crop, depending on the weed species. The composition of a vineyard weed community is influenced by many parameters. Ensuring an evolution of the vine row flora into a desired direction is therefore very complex. A key step towards this goal is to know which factors influence the establishment of the weed community and which types of communities are best suited for vineyards. In this study, we analysed the weed communities of several vineyards in the Lake Geneva region (379 botanical surveys on 117 plots), with the aim to highlight the links between soil management practices (chemical and mechanical weeding, mowing, mulching roll) and phytosociological profiles, biodiversity and selected functional traits (growth forms, life strategies, root depth).
