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.

Arinto clones tolerant to climate change: in depth transcriptomic study of tolerant and sensitive genotypes

Drought and heat waves deriving from climate change have been affecting grapevine plants and altering wine characteristics in the past years, and effects are expected to get worst. Innovative approaches to address this problem have been undertaken in several varieties, that consist in exploring intravarietal variability to identify genotypes that are tolerant to abiotic stress. Such is the case of the variety Arinto, where an experimental population of 165 clones installed according to a resolvable row-column design with 6 replicates, was scanned for several parameters, including surface leaf temperature (SLT). Linear mixed models were fitted to the data of the traits evaluated, and the empirical best linear unbiased predictors (EBLUPs) of genotypic effects for each trait were obtained as well as the coefficient of genotypic variation (CVG) and broad sense heritability.

METHYL SALICYLATE: A TRENDY COMPOUND MARKER OF ZELEN, A UNIQUE SLOVENIAN VARIETY

The wine market interest for autochthonous varieties, particularly from less known wine regions, has significantly raised in the past few years. In that context, Slovenia, a small country from central Europe with a long winemaking tradition, is getting more and more attention, particularly through its range of unique regional varieties. Among them, Zelen, meaning “green” in Slovene, can only be found in the Vipava valley region, located on the western side of the country, near the border with Italy. When they are young, Zelen wines display very singular aromas reminiscent of rosemary, sage and white fruit. Despite its uniqueness, Zelen wine aromatic typicality is poorly documented in the literature.
