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.

Precision viticultural strategy for managing intra-vineyard variability in grape aroma using UAV-based vigour indices

In several cultivars, such as Gewürztraminer and Riesling, grape and wine aromas are determined by volatile terpenoids.

Effect of different plant fibers on the elimination of undesirable compounds in red wine 

The presence of undesirable compounds in wines, such as ota, biogenic amines and pesticides residues, affects wine quality and can cause health problems for the consumer. Additionally, an excess of tannins can produce an undesirable increase in the astringency and bitterness of the wine, so tannins are also a target for reduction. The main tool that a winemaker has to reduce their content in the wine is fining. However, some of the fining agents commonly used in the winery can cause allergies or even increase the protein content in the wine, increasing the turbidity.

The science of fungi in grapevine: An essential new book covering all aspects of fungi in viticulture

Grapevine is one of the world’s most important cultivated plants, domesticated from the wild vine over 11,000 years ago. The fungi associated with it are doubtless as old as the plant itself. Despite their co-evolution with the vine over the centuries, it was only with the invention of the microscope in the seventeenth century that fungi started to be recognised.
