Aroma chemical markers of Durello wines from different vintages and origins: a case study


Wines expressing sensory characters that are representative of their varietal and geographical origins are highly sought after in today’s market. It is therefore of considerable technological interest to investigate the aromatic aspects of specific wines and to identify the odorous substances involved. This study investigated aroma chemical and sensory diversity of Durello DOC white sparkling wines. The production of this white wine, based on the use of Vitis vinifera Durella grapes, is located in the hilly area of the eastern Lessini mountains straddling the border between the provinces of Verona and Vicenza. A peculiarity of this denomination is the subdivision of the production area into a further fifteen sub-regions. The aim of this study was the aromatic characterisation of Durello wines. Particular attention was paid to the impact of ageing/vintage and the sub-region of origin of the grapes.

For this study, a sampling of twenty-one commercial Durello provided by the Durello wine consortium was considered. These wines belonged to four different vintages (2016-2019) and seven sub-zones. Free volatile compounds as well as those obtained from the hydrolysis of  glycosidic precursors were quantified with gas chromatography mass spectrometry (GC-MS) analysis coupled with SPE and SPME extractions. Sensory evaluation of wines was carried out through sorting task performed with semi-trained panel. Wines differed significantly in their aroma chemical composition,  , in particular due to vintage/ageing and sub-zones impact. The effect of ageing was appreciable and involved different biochemical classes of compounds: esters, terpenes, norisoprenoids and methyl salicylate. With ageing, a decrease in acetic esters, some ethyl esters, free and bound terpenes and a simultaneous increase in norisoprenoids, some cyclic terpenes and methyl salicylate were found. Differences attributable to the sub-regions were mainly due to terpenes and norisoprenoids but also benzenoids, fatty acids and some sulphur compounds. The sorting task identified two clusters, the main variable associated to sensory differences was vintage/aging but further elements related to production style were identified. 1,4-Cineole was identified as an aromatic marker of Durello sparkling wine.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
