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.

Novel table grape varieties as “ready-to-eat” products

Consumers are increasingly requesting ready-to-eat products, which are time-saving and convenient. Offering ready-to-eat fruits and vegetables represents a quick and easy way for any consumer to add healthy products to their diet. In this study, we evaluated the aptitude of several table grape varieties to be included in the processing and packaging lines of ready-to-eat products. The following work was based on the characterization of genetic materials and varietal innovation.

Survey of phenological stages of disease-resistant varieties in Friuli Venezia Giulia region

Context and purpose of the study. The primary fungal diseases affecting grapevines in Europe are downy mildew and powdery mildew.

Influence of the irrigation period in Tempranillo grapevine, under the edaphoclimatic conditions of the Duero river valley

Irrigation of vineyards is a matter of controversial arguments at areas of high quality wine production. Besides, the effects of the water in the plant are closer related to the water availability than to the irrigation regime.

Changes in phenolic maturity and texture characteristics of the grape berry under pre-, and post-veraison water deficit

Kékfrankos (Vitis vinifera L.) grapevines grafted on Teleki-Kober 5BB rootstock were submitted to water deficit under greenhouse conditions.

Using remotely sensed (UAV) and in situ field measurements to describe grapevine canopy characteristics

Row orientation and canopy management are essential for high quality grapevine production. Microclimatic conditions of the leaves and fruits can be influenced by the canopy geometry. Remote sensing is a very promising tool to describe vegetative growth and physiological behavior of vineyards. However, the correlation between remotely sensed data and in situ field measurements has been described scarcely in the scientific literature so far. The aim of the study was to correlate remotely sensed data obtained with Unmanned Aerial Vehicle (UAV) with in situ field measurements to describe canopy structure.
