Volatile compounds of base wines for the production of Lessini Durello sparkling wine


AIM: Durello is a sparkling wine produced in the Lessini mountains near Verona. The wine is made from Durella grapes, a native white grape variety with a particularly high acidity. In spite of the small production area (375 ha for only 35 producers), there is a growing interest in this product. However, little is known about the aromatic profiles of these wines. The aim of this work was to characterize the aroma profile of Durella base wines suitable for the production of Lessini Durello sparkling wine.

METHODS: 14 base wines from Durella grapesfrom different producers were used for this study. Solid Phase Microextraction (SPME) and Solid Phase Extraction (SPE) sampling techniques coupled to GC-MS analysis allowed to identify and quantify a total of 62 volatile compounds.

RESULTS: Durello base wines showed relatively high levels of vitispirane, ß-damascenone, ß-citronellol and esters. The norisoprenoid content was higher than in other dry still wines of the sare region (Garganega, Lugana, Pujnot Grigio), which appeared of particular interest considering the early harvest of grapes for sparkling wine production. Odor activity value (OAV) was used to assess the compounds that most contributed to wine aroma. The compounds with an OAV >1 were the ethyl octanoate, ß-damascenone, ethyl hexanoate, isoamyl acetate, octanoic acid, ethyl butanoate, hexanoic acid, TPB, 3-methylbutanoic acid, ethyl 3-methylbutanoate, isoamyl alcohol, ethyl decanoate and finally TDN. The evaluation of the wine aroma profile by means of aromatic series indicated that Durello base wines were characterized by the “fruity” series. Analysis of a subset of Durello wines fromthree different regions within the Lessini Mountains, namely Brenton, Chiampo and Duello , showed that the three areas could be differentiated based on content of methyl salicylate, and the glycosidic precursors of cis-2-hexen-1-ol and 3-oxo-α-ionol.


Base wines for the production of Durello sparkling wine were characterized by high concentrations of norisoprenoids and esters which can contribute to the fruity and tobacco aroma of wine. These results can be particularly useful for winemakers in order to create distinctive wine styles.

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.
