Determinazione della frazione aromatica dei vini, quale strumento per-la valorizzazione del territorio viticolo

Abstract

[English version below]

La caratterizzazione della frazione volatile aromatica dei vini attraverso l’analisi quali­quantitativa dei diversi composti, ha portato corne primo risultato la netta differenziazione delle annate in prova.
Dalla relazione tra analisi sensoriale e analisi chimica, è poi risultato che, per il vino Soave, esteri etilici e acetati sono i composti organoletticamente più importanti e responsabili del-l’aroma fruttato floreale. Alcoli e acidi sono apparsi invece meno utili e sicuri nella caratte­rizzazione varietale e ambientale. E’ quindi importante per ogni vino conoscere i composti aromatici tipici e i loro responsabili analitici, sulla base poi della quantificazione di questi ultimi sarà possibile una caratterizzazione ambientale.

The qualitative and quantitative analysis of the volatile aromatic components of wine has produced, as a first result, a net differentiation of the years being tested.
From the correlation between sensory and chemical analysis we have also found , for Soave wine, that acetates and esters are the most important sensory components; they are responsable for the fruit and floral aromas of wine.
However, alcohols and acids have shown to be less useful in varietal and environmental characterization. It is therefore very important to know, for each wine, the typical aromatic compounds and their chemical composition, and based on their quantification it is possible to value the environment.

Distribution and associated symptoms of grapevine trunk pathogens in South Africa

In recent studies, several grapevine trunk pathogen complexes have been identified from grapevines in South Africa. These pathogens include Eutypa lata, Phaeomoniella chlamydospora, Phaeoacremonium sp., Botryosphaeria sp. and Phomopsis sp. Trunk diseases lead to reduced yield, and grape quality as well as a decline

Advances in the chemistry of rosé winemaking and ageing

The market share of Rosé wine in France has grown from 11 % to 32 % over the last 20 years. Current trends are towards rosé wines of a lighter shade of pink, and where possible, containing a greater concentration in varietal thiols. Grape varieties, the soil on which they are grown, viticultural practices and winemaking technology all impact the polyphenols, color and aromas of rosé wines.

Caratteristiche fisico-chimiche dei suoli coltivati a vite e loro influenza nella diffusione del mal dell’esca

Il mal dell’esca é una malattia della vite della quale sono state studiate sintomatologia, eziologia, patogenesi ed epidemiologia. Essendo una malattia che colpisce soprattutto la parte epigea delle piante, le caratteristiche dei suoli non sono mai state considerate fra le responsabili della sua insorgenza e diffusione.

The use of epifluorescence versus plating to monitor the effect of different parameters on microorganisms in wine

The monitoring of the number of micro-orgranisms in wine is crucial for the wine producer. Traditional counting methods include microscopic enumeration and plating on selective media, which measures the culturability of the cells. The use of epifluorescence microscopy is, however, a method, which can measure both culturability and

Study of wine-growing land (“terroir”) characteristics in the canton of Vaud (Switzerland): ecophysiological behaviour of the vine (cv. Chasselas)

A study of the physiological and agronomical behaviour of the vine (cv. Chasselas) was conducted between 2001 and 2003 by the Swiss Federal Research Station for Plant Production at Changins (Agroscope RAC Changins) on various wine-growing farms (terroirs) in the Canton of Vaud (Switzerland), as part of a study project on Vaudois
