Varietal volatile patterns of Italian white wines


Aroma diversity is one of the most important features in the expression of the varietal and geographic identity and sensory uniqueness of a wine. Italy has one of the largest ampelographic heritages of the world, with more than five hundred different varieties. Among them, many are used for the production of dry still white wines, many classified as Protected Designation of Origins and therefore produced in specific geographical areas with well-defined grape varieties. Chemical and sensory characteristics of the aroma of these wines have never been systematically studied, and the relative diversity has never been described and classified. During this study, which is part of the activities of the D-Wines research consortium, we considered 249 samples of different mono-varietal white wine types (Albana, Arneis, Cortese, Erbaluce, Garganega, Gewurztraminer, Greco di Tufo, Falanghina, Fiano, Lugana, Müller Thurgau, Nosiola, Pallagrello, Pinot Grigio, Ribolla Gialla, Verdicchio, Vermentino, Vernaccia di S. Gimignano) corresponding to major Italian PDOs. Volatile compounds primarily associated with varietal and geographical origin, namely terpenes, norisoprenoids, sulphur compounds and methyl-salicylate, have been analysed by means of different SPME-GC-MS techniques. Multivariate analysis and Hierarchical Cluster Analysis of volatile compounds showed a complex segmentation in which each wine type showed patterns of chemical compounds with similarities within the group but which at the same time partly overlapped with the patterns of other wine types. Despite this, almost all compounds showed significant differences according to wine type. We found that Vermentino was characterized by high concentrations of terpenes and in particular of linalool, whereas for other wine types either sulfur compounds, such as DMS, or norisoprenoids, such as β-damascenone, were found to be significantly discriminant. Similarities between wines from the same grape variety but different geographical origin were also detected, as in the case of Verdicchio and Lugana, both characterized by a higher methyl salicylate content.

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.
