VOLATILE, PHENOLIC AND COLORIMETRIC CHARACTERIZATION OF THREE DIFFERENT LAMBRUSCO APPELLATIONS

Abstract

Lambrusco is a commercially successful sparkling red and rosé wine. With 13.06 million litres sold in 2021 was the second best-selling Italian wine after Chianti. According to National Catalogue of Vine Varieties there are thirteen Lambrusco Varieties with which to date are produced seven PDO wines. Among these, “Lambrusco Salamino di Santa Croce”, “Lambrusco Grasparossa di Castelvetro” and “Lambrusco di Sorbara” are the only ones that can be considered mono-varietal appellations, all located in Modena area. The PDOs contemplate the possibility of producing wines by secondary fermentation either in tank (Charmat method), or in bottle (Classico method). Sur lie is a third method commonly employed for Lambrusco, similar to the Classico method, from which differs for the absence of disgorgement.

The present study has two aims: we intended to provide for the first time a detailed characterization of the volatile chemical and phenolic composition and the colorimetric parameters of the three mono-varietal Lambrusco PDOs “Lambrusco Salamino di Santa Croce”, “Lambrusco Grasparossa di Castelvetro” and “Lambrusco di Sorbara” and we wanted to investigate the influence of the three production methods considered, Charmat, Classico and Sur lie on relevant aroma compounds.

Volatile composition was investigated thanks to GC-MS coupled with different extraction techniques (SPE and SPME). Total polyphenols and anthocyanins were evaluated with specific enzymatic assays, tannins with methyl cellulose precipitable assay. CIElab parameters were studied with a reflectance colorimeter.

We found that the three types wine were differentiated by many volatile compounds. Lambrusco Grasparossa showed higher content of cyclic terpenes and sulphur compounds, Salamino higher content of linalool and 1,4-cineole, while Sorbara showed quite high levels of β-myrcene, 1,8-cineole, TDN, vitispirane and cis-3-hexenol. Fermentation-derived compounds showed a wide intra-varietal variability.

The type of secondary fermentation method (Charmat, Classico or Sur lie) can impact significantly Lambrusco volatile composition, highlighting the importance of various complex phenomena including aging period, adsorption of volatile compounds on yeast lees as well as formation of volatile compounds from amino acids.

With regard to the content of total polyphenols, tannins and anthocyanins, Lambrusco di Sorbara was characterised by a lower content than Grasparossa and Salamino, which was also reflected in the colorimetric parameters.

MICROFLUIDIC PLATFORM FOR SORTING YEAST CELLS ACCORDING TO THEIR MORPHOLOGY

In this work we briefly present a microfluidic device aiming to sort yeast cells according to their morphology. The technology is based upon microfluidic chips made out of Polydimethylsiloxane and glass using soft lithography processes and replica molding. The microfluidic device was used for encapsulating single yeast cells in liquid droplets containing growth medium. Liquid droplet containing yeast cells were sorted using a real time imaging and decision-making process.

Overhead spray water treatment as a mitigation strategy for reducing vine stress and preserving grape quality during heatwaves

Changes in climate have been influencing the quality of wine grapes worldwide. The impact of extreme climate events over short periods is increasingly recognized as a serious risk to grape quality and yield quantity. In this study the mitigation effects of a pulsed water spray on vine canopy during heatwave events has been evaluated for maintaining vine condition during the growing season and grape quality. Vines of three varieties (Malbec, Bonarda, and Syrah) under drip irrigation in the UNCuyo experimental vineyard were treated with an overhead pulsed water spray.

OENOLOGICAL POTENTIAL OF AUTOCHTHONOUS SACCHAROMYCES CEREVISIAE STRAINS AND THEIR EFFECT ON THE PRODUCTION OF TYPICAL SAVATIANO WINES

Due to the global demand for terroir wines, the winemaking industry has focused attention on exploiting the local yeast microflora of each wine growing region to express the regional character and enhance the sensory profile of wines such as varietal typicity and aroma complexity. The objective of the present study was to isolate and compare the indigenous strains of Saccharomyces cerevisiae present in different vineyards in the Mesogeia – Attiki wine region (Greece), evaluate their impact on chemical composition and sensory profile of Savatiano wines and select the most suitable ones for winemaking process.

OTA DEGRADATION BY BACTERIAL LACCASEST

Laccases from lactic acid bacteria (LAB) are described as multicopper oxidase enzymes with copper union sites. Among their applications, phenolic compounds’ oxidation and biogenic amines’ degradation, have been described. Besides, the role of LAB in the toxicity reduction of ochratoxin A (OTA) has been reported (Fuchs et al., 2008; Luz et al., 2018). Fungal laccases, but not bacterial laccases, have been screened for OTA and mycotoxins’ degradation (Loi et al., 2018). OTA is a mycotoxin produced by some fungal species, such as Penicillium and Aspergillus sp., which infect grape bunches used for winemaking.

SUB-CRITICAL WATER: AN ORIGINAL PROCESS TO EXTRACT ANTIOXIDANTS COMPOUNDS OF WINE LEES

Wine lees are quantitatively the second most important wine by-product after grape stems and marc [1]. In order to recycle, distilleries recovered ethanol and tartaric acid contained in wine lees but yeast biomass is often unused. It has already been demonstrated that this yeast biomass could be upcycled to produce yeast extracts of interest for wine chemical stabilization [2]. In addition, it is well known that lees, during aging, release compounds that preserve wine from oxidation.
