Typology of wines in touch with environmental factors of terroirs and grapevine. Application to the Chinon vineyard


According to the vintage, it may be difficult for vine growers to make a decision regarding the type of wine in relation with the soils. The present work aims at proposing typology of wines to the Chinon growers, as a basis for reflection on the wine type in relation with the terroir units and the vintage water supply conditions.
In order to bring out factors associated to a wine structure, a first classification was established thanks to a multiple factorial analysis (MFA), taking into account three qualitative variables resulting from a survey on 506 cultural units of the Chinon vineyard. This first classification was then linked to a second one obtained through an ascendant hierarchical classification (AHC) carried out on an experimental network of the INRA-UVV unit of Angers (49-France). This network of 14 plots, distributed on different terroir units in the Chinon, Bourgueil and Saumur AOC, was monitored for physiological and meteorological data over the 2002-2005 period. The AHC used the data for a humid year (2004) and a dry year (2005). For each year, the experimental plots were grouped into three classes according to their pedoclimatic profiles.
By crossing the two classifications it was possible to elaborate a typology of the Chinon wines in relation with the environmental factors of the terroir units and the water supply conditions of the vintage.
This method, based only on two reference years and a wine typology for the Cabernet franc variety, was successful for analyzing the conditions for the elaboration of a given type of Chinon wine in relation to a precise cartography of the terroir units. This prospective process needs to be generalized.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
