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.

Under trellis cover crop induces grapevine tolerance to bunch rot

Botrytis bunch rot occurrence is one of the most important limitations for the wine industry in humid environments. A positive correlation between grapevine growth and susceptibility to fungal pathogens has been found. In theory the effect of grapevine vegetative growth on bunch rot expression results from direct effects (cluster architecture, nitrogen status among others) and indirect ones (via microclimate). However, a reduction in bunch rot incidence can be achieved in some circumstances without major vine growth reduction. The present study was aimed to test the general hypothesis that bunch rot susceptibility is affected by vine vigor, but other factors associated with grapevine vegetative expression could be even more relevant.

The fundamental role of pH in the anthocyanins chemical behavior and in their extractability during winemaking

The chemical behavior of anthocyanins is considerably affected even by slight pH variations with impor-tant implications for the winemaking as well as for the wine conservation

Evaluating Smoke Contaminants in Wine Using 13C-Labelled Barley as a Fuel Source

Wildfires are becoming more common in many areas of the world that are also associated with wine grape production, especially the Pacific northwest United States, Australia and even some areas of France.

Enological and nutraceutical potential of some grape varieties tolerant to downy mildew and powdery mildew

AIM: Since 2012 the Veneto Region regulation (north-east Italy) allowed wine production using 20 hybrid grapevine varieties selected for their high tolerance to downy mildew and powdery mildew. Characterized by vigour, high grape productivity and low pesticide use, these varieties are suitable to develop sustainable viticulture in mountain areas located at medium altitudes.

Evaluation of the agronomic performance of cvs. Syrah and tempranillo when grafted on a new series of rootstocks developed in spain

The choice of an adequate rootstock is a key tool to improve the performance of grapevine varieties in different ‘terroirs’, as rootstocks confer adaptation to soil characteristics
