Caratterizzazione varietale della CV. Vranac del Montenegro: primi risultati

Abstract

[English version below]

Questo studio ha permesso di raccogliere alcune informazioni sul profilo chimico della cultivar Vranac coltivata in Montenegro. L’uva ha mostrato di raggiungere un buon accumulo zuccherino indipendentemente dall’annata anche se coltivata su suoli diversi. Può raggiungere un buon tenore di antociani e un discreto contenuto di tannini, presenta un profilo antocianico a prevalenza di malvidina-3-G con tenori elevati di antociani acilati. Dal punto di vista aromatico si tratta di una cultivar neutra con un profilo glicosidico a prevalenza di benzenoidi. Dal confronto tra i vini sperimentali e quelli del commercio si può osservare che le potenzialità del vitigno sono buone ma vanno potenziate con un’adatta tecnica di vinificazione per cui saranno necessarie ulteriori prove tecnologiche.

This study has allowed us to gather some information on the chemical profile of Vranac cultivars grown in Montenegro. The grape has been shown to achieve good sugar accumulation independent of the year even if grown on different soils. It can reach a good content of anthocyanins and medium of tannins. Malvidina-3-G was predominant in the anthocyanic profile and the levels of acylated anthocyanins were high. It is a neutral cultivar with a prevalence of glycosidic benzenoids in the aroma profile. The comparison between the experimental and commercial wines can assume that the potential of the grapes are good but must be reinforced with a suitable winemaking which will require further studies.

HYDROXYTYROSOL PRODUCTION BY DIFFERENT YEAST STRAINS: SACCHAROMYCES AND NON-SACCHAROMYCES AND THE RELATION WITH THE NITROGEN CONSUMPTION

Hydroxytyrosol (HT) is a phenolic compound with extensive bioactive properties. It is present in olives, olive oil and wines. Its occurrence in wines is partly due to yeast synthetise tyrosol from tyrosine by the Ehrlich pathway, which is subsequently hydroxylated to .
The aim of the present work is to study how different yeast strains can influence in the HT production and, how the different nitrogen consumption of each strain can interfere the production of bioactive compounds.

Anthocyanins, flavonols and hydroxycinnamates of eight vitis vinifera cultivars from the balearic islands

In 2008 the anthocyanin, flavonol and hydroxycinnamate (HCT) contents of the skins of five coloured berry cultivars (‘Escursac’, ‘Esperó de Gall’, ‘Galmeter’, ‘Valent negre’ and ‘Vinater negre’), of two white cultivars (‘Argamussa’ and ‘Prensal blanc’) and of one weakly rose cultivar (‘Giró ros’), native from Balearic Islands, were characterized.

USDA national grapevine germplasm resources: new curators, new directions

The National Plant Germplasm System (NPGS) in the United States Department of Agriculture safeguards numerous species. Grapevines are split in two locations: Davis, CA and Geneva, NY. The two germplasms maintain 43 Vitis species with over 4500 genetically unique accessions.

Phenolic compounds of wine spirits resulting from different ageing technologies: behaviour during the storage in bottle

Phenolic compounds are released from the wood into the wine spirit (WS) during the ageing process, and are of utmost importance to the colour, flavour, taste and the overall quality acquired by this spirit drink.1 Their concentrations in the WS and the related effects mainly depend on the kind of wood (oaks vs chestnut), toasting level and ageing technology (traditional using wooden barrels vs alternative).1,2,3

Shifting wine consumption trends (2019-2024): market dynamics, sustainability, and consumer preferences

This study examined the evolution of wine consumption trends from 2019 to 2024, analyzing market dynamics, sustainability preferences, and generational shifts in consumer behavior.
