Wines empirical perception and growers management practices in the Anjou Villages Brissac vineyard (France)

Abstract

The concept of viticultural terroir includes soil, sub-soil, and climatic factors but also many management viticultural and oenological practices which are chosen according to know-how of the winegrowers. Most of the terroir studies deal with analysis of the variability of plot ecophysiological parameters and, also, their impacts on vine functioning (mainly water balance and vine earliness). Usually, in the research networks, management practices are fixed (cultivar, root-stock, soil cover crop). However, viticultural and oenological practices play a major role in the grape composition. For this reason, the present paper proposes to study terroir impact regarding an inventory of both environmental factors, and management practices that are used for the production of Anjou Villages Brissac (AVB) or Anjou Rouges (AR) wines. In addition, the empirical perception of sensory characteristics of AVB wines by farmers was studied.
The goals of this work were to compare ‘AVB’ practices to AR practices. Also, an approach of links between the empirical sensory perception of wine and types and practices classes, was carried out. To realize the study an exhaustive survey has been made at both farm and plot scales according to the nature of questions. This survey was proposed to all winegrowers of AOC AVB (41 farmers and about 100 ha vines). AVB wines but also AR wine can be produced on this area.
Practices and practices classes had been studied and crossed with environmental factors of the plots. Statistical analysis allowed showing which practices and practices modalities are significantly different between AVB and AR plots. 18 viticultural and 10 oenological practices are statistically significant to distinguish AVB plots from AR plots. Winegrowers think AVB wine is a well-known figure of the wines of Val de Loire with good oral characteristics as fine tannins, matter and volume, intense colour and ripped fruit aromas. Results have been also crossed with the winegrowers’ perception of AVB wines characteristics.
Prospects of this study are 1) to compare survey sensory perception with tasted sensory profiles and 2) to validate practices combinations with an experimental study using a plot network.

Terroir analysis and its complexity

Terroir is not only a geographical site, but it is a more complex concept able to express the “collective knowledge of the interactions” between the environment and the vines mediated through human action and “providing distinctive characteristics” to the final product (OIV 2010). It is often treated and accepted as a “black box”, in which the relationships between wine and its origin have not been clearly explained. Nevertheless, it is well known that terroir expression is strongly dependent on the physical environment, and in particular on the interaction between soil-plant and atmosphere system, which influences the grapevine responses, grapes composition and wine quality. The Terroir studying and mapping are based on viticultural zoning procedures, obtained with different levels of know-how, at different spatial and temporal scales, empiricism and complexity in the description of involved bio-physical processes, and integrating or not the multidisciplinary nature of the terroir. The scientific understanding of the mechanisms ruling both the vineyard variability and the quality of grapes is one of the most important scientific focuses of terroir research. In fact, this know-how is crucial for supporting the analysis of climate change impacts on terroir resilience, identifying new promised lands for viticulture, and driving vineyard management toward a target oenological goal. In this contribution, an overview of the last findings in terroir studies and approaches will be shown with special attention to the terroir resilience analysis to climate change, facing the use and abuse of terroir concept and new technology able to support it and identifying the terroir zones.

Effect of maceration conditions during the winemaking of withered Corvina grapes on wine polyphenols and anthocyanins

Amarone is an Italian red wine with worldwide recognition and high added value. In Amarone wines, grapes undergo a withering process before vinification; this leads to a modification in the concentrations of sugars, acids, and secondary metabolites.

Use of mathematical modelling and multivariate statistical process control during alcoholic fermentation of red wine

Cyberphysical systems can be seen in the wine industry in the form of precision oenology. Currently, limitations exist with established infrared chemometric models and first principle mathematical models in that they require a high degree of sample preparation, making it inappropriate for use in-line,

The chances for using non-saccharomyces wine yeasts for a sustainable winemaking

Climate changes and the trend towards organic and more sustainable winemaking highlighted the need to use biological methodologies. The reduction in the use of SO2, the need of the reduction of ethanol content of wines and the now need to reduce or eliminate chemical phytosanitary products, have prompted the search for alternative practices.
