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.

Beyond colors of rosé wines: impact of origin and winemaking technology on their color, polyphenol and thiol compositions

Rosé wine consumption is rapidly increasing with its market share in France that has grown from 11 % to 32 % in less than 20 years. A recent trend is also to produce rosé wines with lighter colors. Varieties, terroir and technology certainly have an influence on rosé wine colors.

Cultivation of grapes Chardonnay in soils with management practices biodynamic and conventional

The cultivation of grapes, can be accomplished with the use of different systems and practices of agricultural management, the choice of the system to be followed in the vineyard, depends on the conditions of available resources, these being: natural, economic, social, cultural and territorial. As well, it is relevant to know the characteristics of the soil of the vineyard. In the last decade, has been recurrent use of agricultural practices which date back to milinares traditions, with the aim of promoting a recovery of soil and lead the management of cultivation with less damage to the ecosystem. The study here, aimed to quantify the environmental impacts caused in the use of nutrients in conventional tillage and of grapes in the biodynamic agricultural properties in the state of Rio Grande do Sul- Brazil.

Analyses of a long-term soil temperature record for the prediction of climate change induced soil carbon changes and greenhouse gas emissions in vineyards

The evaluation of the current and future impact of climate change on viticulture requires an integrated view on a complex interacting system within the soil-plant-atmospheric continuum under continuous change. Aside of the globally observed increase in temperature in almost all viticulture regions for at least four decades, we observe several clear trends at the regional level in the ratio of precipitation to potential evapotranspiration. Additionally the recently published 6th assessment report of the ipcc (the physical science basis) shows case-dependent further expected shifts in climate patterns which will have substantial impacts on the way we will conduct viticulture in the decades to come.
