Terpenoids and norisoprenoids in italian red wines

Abstract

AIM: Terpene compounds are associated with floral notes and are characteristic of aromatic grape varieties such as Muscat (Jackson, 2008). They are generally considered to potentially contribute to the aroma of white wines. However, there is a growing interest towards the potential contribution of terpene compounds to the aroma of red wines. The aim of this work was to investigate the occurrence of different terpenes in red wines from Italian varieties.

METHODS: For this study wines from 11 mono-varietal Italian red wines from 12 regions were used (19 Sangiovese, 11 Nebbiolo, 10 Aglianico, 11 Primitivo, 10 Raboso del Piave, 9 Cannonau, 11 Teroldego, 3 Nerello, 9 Montepulciano, 7 Corvina). All samples were from vintage 2016 and none of them had been in contact with wood. A total of 19 terpenes and 7 norisoprenoids were analysed by mean of SPME-GC-MS analysis using a DVB-CAR-PDMS fiber. The wines were collected in the framework of the activities of the D-Wines (Diversity of Italian wines) project.

RESULTS: Significant differences among varieties were observed for basically all the compounds analyzed with the exception of limonene. Overall, the concentrations of the various terpenes remained in the same order of magnitude. However, some differences are noticeable between varieties. Corvina was characterized by higher level of linalool, followed by Aglianico, Nebbiolo, Primitivo and Sangiovese. Cyclic terpenoids appeared as good varietal markers, for instances Montepulciano was characterized by 1,4-cineole and 1,8-cineole, whereas Sangiovese showed higher levels of p-cymene, α-terpinene and 1,4-cineole. Higher terpinene-1-ol content was characteristic of Montepulciano and Raboso wines. Relatively high levels of the norisoprenoid β-damascenone were found in Cannonau up to 3.68 µg/L.

CONCLUSIONS:

This study provide the first survey of a large number of terpenoids and norisoprenoids in different mono-varietal Italian red wines. The results showed that a large number of terpenoids were present in Italian red wines with specific profiles related to the varieties.

In line monitoring of red wine fermentations using ir spectrospcopy

There has been a shift in modern industry to implement non-destructive and non-invasive process monitoring techniques (Helmdach et al., 2013).

High-altitude vineyards under extreme conditions in the PIWI context of cultivation: economic and marketing evidence from an exploratory study in Northern Italy

Viticulture has spread to unexpected locations, such as high-altitude terrain. Among these, high-altitude viticulture has captured considerable attention, not only for the uniqueness of its products and landscapes but also because it offers an effective response to climate changes
The aim of this study is to analyse and compare wineries that used Piwi varieties (acronym for the German Pilzwiderstandfähig, i.e., cryptogame-resistant) at high altitudes (between 500 and 920 m a.s.l.) with the traditional non-mountainous viticulture model.

Geochemistry of Vrbničko Polje (Croatia) winegrowing site

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production.

Cover crop influence on water relations, yield, grape and wine composition of Pinot noir

The effect of cover crop on the water relations, yield and grape composition of Pinot noir vines was investigated during two seasons (2003 and 2004) in a gravely soil located in Tarragona (Spain). Seventeen-year-old vines, grafted onto R110 and trained onto a Ballerina training system, were used.

Unraveling vineyard site from vintage contributions: Elemental composition of site-specific Pinot noir wines across multiple vintages

Understanding vineyard site contribution to elemental composition of wines has, historically, been limited due to lack of continuity across multiple vintages, as well as lack of uniformity in scion clone and lack of controlled pilot-scale winemaking conditions. We recently completed our fifth vintage, and have elemental composition characterizing wines from four vintages (2015–2018)
