Evolution of several biochemical compounds during the development of Merlot wine in the vinegrowing “Terroir” of Valea Călugăreasa

Abstract

The qualitative and quantitative distribution of the phenolic compounds in red wines depends on cultivars features, on grapes maturation state, on grapes processing technology including must obtention, as well as on maceration-fermentation method (Margheri, 1981). The last two factors are responsible for the different phenolic composition of the wines produced from the same cultivar. Dealu Mare vineyard offers favourable conditions for a higher capitalization of Cabemet Sauvignon, Pinot noir, Merlot and Fetească neagră cultivars. The red wines having a middle or high content in phenolic compounds and a well-balanced phenolic composition are advisable for being developed in oak barrels (Sommers and Pocock, 1990).

The study which was undertaken at the Research Institute for Viticulture and Enology, Valea Calugareasca, during 1987-1995 was pursuing both the evolution of phenolic composition and wines color, and the influence of the keeping container on the quality of Merlot wine.

Neural networks and ft-ir spectroscopy for the discrimination of single varietal and blended wines. A preliminary study.

Blending wines from different grape varieties is often used in order to increase wine complexity and balance. Due to their popularity, several types of blends such as the Bordeaux blend, are protected by PDO legislation.

Relation entre les caractéristiques des fromages d’Appellation d’Origine Contrôlée et les facteurs de production du lait

Les fromages d’Appellation d’Origine Contrôlée (AOC) représentent un enjeu économique important pour la filière laitière (11 % des fromages produits en France sont des fromages d’AOC, et dans certaines régions de montagne, cette proportion dépasse 50 %). Les spécificités de ces fromages et leurs liaisons avec les caractéristiques du terroir constituent un système complexe où interagissent en particulier la technologie fromagère et les caractéristiques des laits (composition chimique en particulier). Ces dernières dépendent elles-mêmes des caractéristiques des animaux (origine génétique, facteurs physiologiques, état sanitaire) et de leur mode de conduite (alimentation, hygiène, traite…) (fig. 1). L’influence de ces facteurs de production (alimentation et type d’animal en particulier) sur les caractéristiques des fromages est fréquemment mise en avant par les fromagers, sur la base d’observations empiriques. Il existe cependant très peu de travaux expérimentaux sur le sujet, en raison, entre autres, de la difficulté de séparer correctement les effets propres de ces facteurs d’amont de ceux liés à la technologie fromagère.

Wine aging : a bottleneck Story ?

The sporadic oxidation of white wines remains an open question, making wine shelf life a subjective debate. Through a multidisciplinary synoptic approach performed as a remarkable case study on aged bottles of white wine, this work unraveled a yet unexplored route for uncontrolled oxidation.
