Aroma diversity of Amarone commercial wines


Amarone is an Italian red wine produced in the Valpolicella area, in north-eastern Italy. Due to its elaboration with withered grapes, Amarone is a rather unique example of dry red wine. However, there is very limited data so far concerning the volatile composition of commercial Amarone wines, which also undergo a cask aging of 2-4 years before release. The present work aims at characterizing the aroma composition of Amarone and to elucidate the relationships between chemical composition and sensory characters.  Two sets of Amarone wines from different vintages 2015 (17 wines) and 2016 (15 wines) were analyzed. The analyses were carried out by means of Gas Chromatography-Mass Spectrometry (GC-MS) and extracted by Solid Phase Extraction (SPE) and Solid Phase Micro Extraction (SPME). In addition, the sampled wines were subjected to a sensory evaluation in the form of sorting task. From both data sets, 70 volatile compounds were successfully identified and quantified, 30 of which were present in concentrations above their odor thresholds in all the samples. Using the odor activity value (OAV), the compounds that potentially contribute to Amarone perceived aroma are b-damascenone, ethyl and isoamyl acetate, ethyl esters (hexanoate, octanoate, butanoate, 3-methybutanoate), 4-ethyl guaiacol, 3-methylbutanoic acid, dimethyl sulfide (DMS), eugenol, massoia lactone, 1,4-cineol, TDN, cis-whisky lactone. The only differences found between the two vintages’ OAV list, could be observed in the presence of dimethyl trisulfide (DMTS) in the vintage 2015; whereas in the 2016 set g-nonalactone and trans-whisky lactone were found. Regarding the compounds that impart the most differences across both vintages, OAV max/min, where 4- ethyl phenol, 4-ethyl guaiacol, 1,8-cineole, 1,4-cineole, dimethyl sulfide (DMS). Results from the sorting task sensory analysis of the 17 wines from vintage 2015 showed three clusters formed. Cluster 1 composed of eight wines and described as “red fruit”, “solvent” and “sweet spices”. Cluster 2 formed by four Amarone was associated mainly with the “animal” and “oak/toasted” attributes. And cluster 3 (five wines) described with the attribute “cooked fruit”. While in the sorting task of vintage 2016 (15 wines) two clusters were formed: cluster A formed by 5 wines described as “cooked fruit” and “solvent”; and cluster B (10 wines) associated with the attributes “sweet spices”, “red fruit” and “oak/toasted”. To our knowledge the present research is the first attempt to identify and classify Amarone della Valpolicella commercial wines in terms of aroma. This study provides a list of compounds that can be characteristic of Amarone wine and that have been consistent across two vintages coming from different wineries . Moreover, from the volatiles analyzed, compounds such as dimethyl sulfide (DMS) and cineoles have been singled out as potential aroma markers of diversity in Amarone wines

austrianvineyards.com: online viewer of all designations of Austrian wine

To digitally record and present all the origins of Austrian wines in the same perfect and clear way was the motivation for the Austrian Wine Marketing Board (Austrian Wine) to start with the project in 2018. In June 2021 the results were presented to the public in an online viewer showing all the designations of Austrian wine, available at https://austrianvineyards.com in a largely barrier-free manner. The online viewer provides tailored individual maps fitted to the respective zoom level. The smallest unit of wine-origins in Austria is called Ried and is displayed in a plot-specific manner highlighting areas under vine. Information on the Ried include administrative district, winegrowing municipality, cadastral municipality, large collective vineyard site, specific winegrowing region, generic winegrowing region, winegrowing area and, in many cases, an illustrative picture. Complementary data on the size, elevation (minimum-maximum), orientation (in 8 sectors plus flat) and gradient (minimum, maximum, average) are based on the area under vine according to the EU’s Integrated Administration and Control System. Additional information covers climate data. The diagrams are taken from the monthly breakdown of data in the annals of the Central Institute for Meteorology and Geodynamics, Austria provide a display of values for air temperature, precipitation, and sunshine hours for the reference year and the long-term average. Seasonal aggregated data on temperature, precipitation, and sunshine hours complete the display. Short descriptions with emphasis on geology and soil, field name in historical maps, etymology of the denomination, and main planted variety complements the available information for the main designations in the online viewer. These descriptions are compiled by winegrowers, geologists, historians, and journalists. All the information and data can be extracted to a pdf-file. Printed vineyard maps are also available. Missing content regarding wine origins in Styria will be completed in winter 2021/22.

Combined use of leaf removal and natural shading to delay grape ripening in Manto negro (Vitis vinifera L.) under deficit irrigation 

The increasingly frequent heat waves during grape ripening pose challenges for premium wine grape production. This makes the development of irrigation and canopy management techniques of great importance to maximize yield and grape quality. A field experiment was carried out during 2021 and 2022 using Manto negro wine grapes to study the effect of two irrigation strategies and different light exposure levels on grape quality.

Dynamics of soil and canopy temperature: a conceptual approach for Alentejo vineyards

Climate change imposes increasing restrictions and risks to Mediterranean viticulture. Extreme heat and drought stress events are becoming more frequent which puts in risk sustainability of Mediterranean viticulture. Moreover row crops e.g. grapevine for wine, are increasingly prone to the impact of more intense/longer exposure time to heat stress. The amplified effects of soil surface energy reflectance and conductance on soil-atmosphere heat fluxes can be harmful for leaf and berry physiology.

Influence of trellis system and shoot density in yield and grape composition of a vineyard of Cabernet Sauvignon, in warm climate

In vineyards grown in warm areas, it is usual that the stage of maturity of the grapes is fast and easily reach a high concentration of sugar and low acidity, but not a adequate phenolic maturation. The geometry of the trellis system and the shoot density can modify the microclimate of the cluster and, therefore, the maturation process.
