Un exemple de valorisation d’une étude de terroir au sein d’une unité coopérative de production à Saint Hilaire d’Ozilhan (Gard) dans les cotes du Rhône

Abstract

Les vignerons de la cave coopérative intercommunale de Saint Hilaire d’Ozilhan pratiquent depuis dix ans la sélection au terroir. Il y a cinq ans, après s’être dotés d’une structure commerciale performante, et soucieux d’améliorer la connaissance de leurs terroirs et de mieux maîtriser quantitativement et qualitativement la gamme de typicité qu’ils peuvent élaborer, ils ont demandé au Syndicat Général des Vignerons Réunis des Côtes du Rhône et à l’Institut Coopératif du Vin de les aider à mettre en place une démarche permettant de mieux juger le comportement des cépages Grenache et Syrah dans les différents terroirs, puis de valoriser ce travail au travers de l’amélioration de la qualité des produits.

Influence of canopy management on yield, grape and wine quality. Relationship between the potassium content and pH in must and wine of the cultivar “Tempranillo”

In recent years red wines are being produced in Andalusia from indigenous and foreign grape varieties, one of which is the Spanish variety Tempranillo.

How to improve the mouthfeel of wines obtained by excessive tannin extraction

Red wines felt as astringent and bitter generally show high content of tannins due to grape phenolic compounds’ extraction in the maceration process. Among different enological practices, mannoproteins have been shown to improve the mouthfeel of red wines (1) and the color (2,3). In this work, we evaluated the effect of mannoproteins on the mouthfeel profile of Sangiovese wines obtained by excessive tannin extraction.

A new approach for sensory characterization of grape. Relationship with chemical composition

Characterize taste and mouthfeel properties of grapes elicited by the phenolic fraction (PF) of grape berries and establish relationships with chemical variables. METHODS: As many as 31 diverse grape lots of Tempranillo Tinto and Garnacha Tinta from three different regions were harvested. Grapes were destemmed and macerated in 15% of ethanol for one week and extracts were submitted to solid phase extraction. The recovered polyphenolic fraction was reconstituted in wine model and characterized by a panel of 21 wine experts employing a list of 23 taste and mouthfeel-related attributes following a rate-k-attributes methodology. RESULTS: Six significant attributes among the 31 samples differed based on ANOVA results: “dry”, “coarse”, “bitter”, “dry on tongue”, “sticky” and “watery”. PCA with VARIMAX algorithm was calculated.
