Study of the sensory dimension of the wine typicality related to a terroir and crossing with their viticultural and oenological characteristics

Abstract

The typicality of a product can be characterized by properties of similarity in relation to a type, but also by the properties of distinction. The typicality related to the soil is associated with a delimited geographical origin, and with asserted characteristics. The aim of this study is to determine the sensory profile of typical wines and to interrelate with their technical characteristics. A quantitative descriptive analysis was carried out by an expert panel on 34 wines from Vintage 2005 (23 “Anjou-Villages Brissac” and 11 “outsiders”). All these wines came from plots being able to product the A.O.C. “Anjou-Villages Brissac”. In addition, a characterization of the typicality of the products was carried out with “just about right” profiles, by a group of professionals of this area, from descriptors raised by discussion with all the producers of the area. Finally, a crossing of the sensory data with viticultural and enological practices was carried out.
The results showed the relevance of the expert panel in the discrimination of the products. Two groups could be distinguished, one consisted essentially of wines “Anjou-Villages Brissac” and the other consisted essentially of wines “outsiders”. The panel of professionals proved to be relevant on the characterization of the total quality of the wines, but did not appear consensual for more precise descriptors. The crossing of sensory profiles with some technical acts showed significant effects of “thinning out of leaves”, “disbudding”, “maceration” and “fermentation with industrial yeast” on sensory characteristics.

Investigating water stress-related seasonal and spatial patterns and the possible links with juice and wine compositional parameters

The mapping of spatial variability in vineyards offers the potential to implement zonal management strategies with the aim to optimize economic benefits and increase sustainability by managing natural resources, such as water used for irrigation, more optimally. This study characterized the (natural) variability in plant water status in a commercial Cabernet Sauvignon block, using remote sensing techniques, and identified the impact of this variability on the yield, and juice and wine composition. From the field data collected over two growing seasons, we demonstrated that remote sensing techniques are a practical and powerful tool for mapping spatial variability within vineyard blocks.

Vineyard management strategies adopted to mitigate the impacts of climate change affect the evolution of phenolics and color during bottle aging of Aglianico wines

In recent years several strategies have been proposed to cope with the effect of climate change on grape berry quality but only a few studies have dealt with the influence of management practices implemented in the field (e.g. irrigation,summer pruning, etc.), on the evolution of wines over time.

Physiological response of new cultivars resistant to fungi confronted to drought in a semi-arid Mediterranean area

Water is one of the most limiting factors for viticulture in Mediterranean regions. Former researches showed that water shortage hampers both vegetative and reproductive developments. INRA is running programs to breed varieties carrying QTL of tolerance to major fungi, i.e. powdery and downy mildews. Some varieties have been already certified or are close to be certified. However, little is known about the response of these varieties to water deficit, which behavior is critical for their development. This study characterized physiological responses of 4 new varieties to water deficit and described relationship between them.

1H-NMR-based Untargeted Metabolomics to assess the impact of soil type on the chemical composition of Mediterranean red wines

Untargeted metabolomics has proven to be an effective method to study the impact of the terroir on metabolic profile of wines. In this context, the aim of this study was to evaluate the effects of different soil types on the chemical composition of Mediterranean red wines, through 1H-NMR metabolomics combined with chemometrics.Grapes from Nero d’Avola L. red cultivar cultivated on four different soil types were separately vinified to obtain four different red wines.One milliliter of raw wine was analyzed by means of a Bruker Avance II 400 spectrometer operating at 400.15 MHz
