Proposal of a procedure for sensory characterisation of wines from different subareas of a same D.O.C. (V.Q.P.R.D.)

Abstract

In the course of the present work, which is the first part of a study on the “characterization of Barbera dell’Oltrepo Pavese D.O.C.” 30 wines Barbera from 1993 vintage have been compared only regarding their sensory characteristics. An unstructured scale card, composed by 15 descriptors have been used. The terms of description in the card have been those more frequently mentioned by the assessors during some preliminary degustation sessions. All data from sensory evaluation have been elaborated by some consensus statistical methods (Univariate regression, Generalized Procrustes analysis, Consensus PLS) to eliminate systematic differences between judges, consequence of personal scale and/or confusion between attributes. The differences among samples are only slightly changed when the consensus techniques have been used. With the exception of some wines, a good uniformity in sensory characteristics was observed. Relations between wine sensory descriptors and the altitude of the vineyards have been also studied using PLS method.

Viticultural zoning of the country of Mendoza, Argentina. Study of the first zone : department of Luján de Cuyo. Statement of the study year 2002

La région viticole de Mendoza est la principale zone vitivinicole d’Argentine qui se compose de 3 oasis (Nord, Valle de Uco, Sud). La première zone vitivinicole, située dans l’oasis Nord, est composée par les département de Luján de Cuyo et Maipu. C’est la zone de production la plus ancienne et la plus reconnue pour la qualité de sa production. Ce travail se porte plus particulièrement sur le département de Luján de Cuyo qui constitue le lieu traditionnel de production du Malbec argertin. Ce travail propose de caractériser les terroirs et de mettre en avant leurs typicités.

Identification of caffeic acid as a major component of Moscatel wine protein sediment

Proteins play a significant role in the colloidal stability and clarity of white wines [1]. However, under conditions of high temperatures during storage or transportation, the proteins themselves can self-aggregate into light-dispersing particles causing the so-called protein haze [2]. Formation of these unattractive precipitates in bottled wine is a common defect of commercial wines, making them unacceptable for sale [3]. Previous studies identified the presence of phenolic compounds in the natural precipitate of white wine [4], contributing to the hypothesis that these compounds could be involved in the mechanism of protein haze formation.
