La variabilità del colore in vini rosati dell’Italia meridionale

Abstract

[English version below]

Nei vini rosati, è il colore ad avere il primo impatto con il consumatore. Esso risulterà tanto più accattivante, quanto più elegante e raffinato si presenta.
Le caratteristiche cromatiche dei vini rosati si evidenziano attraverso un tenue colore rosa, a cui spesso si accompagnano riflessi viola o aranciati.
Gli antociani ed il pH sono i principali parametri del colore dei vini rossi e rosati, per cui sono stati considerati nella presente ricerca.
Gli antociani, in particolar modo, sono stati considerati nella qualità, quantità e nello stato di monomeri o combinati in cui si trovano nelle materie prime (uve), nei vini ed in alcuni di essi le evoluzioni ai quali vanno incontro durante lo stoccaggio a differenti temperature.
Con il presente lavoro, si è voluto dare un contributo di studio alle caratteristiche cromatiche dei più diffusi vini rosati che attualmente sono prodotti in alcuni territori dell’Italia meridionale, discuterle in base a come sono concepite dal vinificatore e come le gradirebbe il consumatore.

]]Colour is the first thing consumers notice in rosé wines. The more elegant it is, the more appealing the wine will be. Rosé wines are a soft shade of pink, often tinged with delicate hues of purple or orange. Anthocyanins and pH are the main determiners of colour and are therefore discussed in this paper, focussing in detail on the quality and quantity of the anthocyanins and whether they occur as monomers or polymers in the grapes and the wines. The evolution some anthocyanins undergo during storage at a range of temperatures has also been studied.

The paper aims to broaden knowledge on the chromatic characteristics of the more common rosé wines currently produced in southern Italy and discuss how the producers perceive their wines and how consumers would like them to be.

The terroir of Carnuntum: investigation of the physiogeographic characteristics and interdisciplinary study of viticultural functions of the Carnuntum wine district, Austria

During a three-year period, the vineyards of the Carnuntum wine district are investigated for their terroir characteristics. The interdisciplinary study is aimed at the description of the physiogeographic

Innovative red winemaking strategy: biosurfactant-assisted extraction and stabilization of phenolic compounds

The color is the first attribute perceived by consumers and a major factor determining the quality of red wines. This depends mainly on the content of grape anthocyanins and their extraction into the juice/wine during winemaking. Furthermore, these compounds can undergo reactions that influence the chemical and sensory characteristics of the wine. Monomeric forms are prone to oxidation and adsorption on solid parts.

Mapping and tracking canopy size with VitiCanopy

Understanding vineyard variability to target management strategies, apply inputs efficiently and deliver consistent grape quality to the winery is essential. However, despite inherent vineyard variability, the majority are managed as if they are uniform. VitiCanopy is a simple, grower-friendly tool for precision/digital viticulture that allows users to collect and interpret objective spatial information about vineyard performance. After four years of field and market research, an upgraded VitiCanopy has been created to achieve a more streamlined, technology-assisted vine monitoring tool that provides users with a set of superior new features, which could significantly improve the way users monitor their grapevines. These new features include:
• New user interface
• User authentication
• Batch analysis of multiple images
• Ease the learning curve through enhanced help features
• Reporting via the creation of colour maps that will allow users to assess the spatial differences in canopies within a vineyard.
Use-case examples are presented to demonstrate the quantification and mapping of vineyard variability through objective canopy measurements, ground-truthing of remotely sensed measurements, monitoring of crop conditions, implementation of disease and water management decisions as well as creating a history of each site to forecast quality. This intelligent tool allows users to manage grapevines and make informed management choices to achieve the desired production targets and remain profitable.

Effect of the plant sink/source balance on the chemical content of red table grapes (Vitis vinifera L.).

PPhloem transport of assimilates provides the materials needed for the growth and development of reproductive structures, storage and developing organs, and has long been recognized as a major determinant in crop yield.

The role of molecular ecophysiology in terroir expression

Terroir is a complex concept which associates soil, climate, grape variety and cultural practices that include the training system and oenological techniques. It is a type of social construction with man at its centre. The typicality of a wine is also a social construction which is the result of an agreement among specialists vis à vis a given quality of the wine whose references are the wine’s origins (e.g. terroir) and taste.
