Sangiovese is the most cultivated red grape variety in Italy where it is certified for the production of several Protected Designation of Origin (PDO) wines, and it is one of the most cultivated Italian red grape varieties in California. Despite the global distribution of this variety, there is a lack of international studies on Sangiovese grapes and wines. For this reason, the present study aimed to compare 20 commercial Sangiovese wines from 2017 harvest, 9 produced in Italy (Tuscany) and 11 in California, in order to evaluate the intrinsic and perceived quality. The eligibility, identity, and style properties (the intrinsic quality) of the wines were evaluated. A group of 11 Italian experts evaluated the perceived quality by rating the typicality of the wines. The experimental data showed that the intrinsic quality of Sangiovese wine samples was affected by the growing area; in particular, the wine resulted very different for the color indices and polyphenol composition. The above differences in intrinsic quality levels did not lead to a different evaluation of the perceived quality (typicality) by the wine experts. The results evidenced that Sangiovese variety is recognizable also if grown outside its original terroir, and fresh and fruity wines were considered more typical. This study expands our current knowledge of Sangiovese wines and the contribution of regional characteristics to the composition of wine.

The quality of wines has often been associated with their geographical area of production, as well as the grape variety used in their elaboration. Many research studies have been carried out to characterize and differentiate between red wines labeled with Protected Designation of Origin (PDO) from different geographical areas, but very few have been carried out on white and rosé wines. The objective of this work was to characterize white and rosé PDO wines from different geographical areas of Spain very close to each other elaborated with different grape varieties and select the variables that most contribute to their differentiation. Analysis of variance (ANOVA) and principal component analysis (PCA) were used as statistical methods. The ethanol content was the nonvolatile variable that most contributed to differentiating between some of the white and rosé wines according to their PDO. The white wines from RD (Ribera del Duero) and BI (Bierzo) were characterized by a high terpenic content (floral notes) while the wines from RU (Rueda), TO (Toro) and CI (Cigales)by a high content of ethyl esters and alcohol acetates (fruity aromas). The rosé wines elaborated with the Mencía grape variety from BI were characterized by their highest polysaccharidic content, which could have a positive sensory effect on the mouthfeel. The rosé wines from CI were characterized by their volatile profile complexity, having the highest content of volatile compounds from the oak wood, terpenes and C6 alcohols which provide pleasant woody, floral and herbaceous aromas. On the contrary, the RD wines were richest in alcohol acetates responsible for fruity aromas.

Perceived Quality Of Life

AbstractAlthough it has been assumed for many years that there is a relationship between the subjectively perceived quality of residential environment and quality of life, empirical evidence for the existence of such a link has been inconclusive. It is also assumed that the perception of residential environment in a certain way covariates with the behavior of people in this environment; Empirical support for this correlation is now all the more problematic. The objectives in the our research project were as follows: (1) enriching the current knowledge about those links between the perceived quality of various residential areas and their inhabitants’ experienced quality of life, and (2) examining the co-variables between the sense of satisfaction with the residence and declared pro-social and civic behavior. For the purpose of our study, we proposed an original theoretical framework integrating several available man-environment-behavior relationship concepts with the more general homeodynamic regulation concept for achieving psychological balance. Sixty-two people aged 18 to 85 took part in the research. Two groups were identified in the analysis: young adults and seniors. No significant correlation was found between the respondents’ perceived quality of life and their satisfaction with the quality of the environment they inhabited. It was almost exclusively seniors who undertook activities to benefit the residential area, and their life quality was correlated with this activity. Young adults turned out to be generally inactive. Correlations between pro-social and civic behavior and the residential area’s assessed quality proved to be weak and simple, but had different directions and dimensions in young adults and seniors.

The study of the indigenous gene pool of Vitis vinifera L. of diff erent zones of viticulture with the involvement of molecular genetic methods is an urgent due to the wide diversity of grape varieties. The territory of Abkhazia is a unique zone, one of the hotbeds of the emergence of cultural grapes. «Kachich» is the oldest Abkhazian grape variety, known for the quality of wines obtained from its harvest. The variety is more resistant to fungal diseases compared to popular European varieties cultivated in modern Abkhazia, and is particularly resistant to rot of berries. However, often the local population calls old bushes by the name «Kachich», which give grapes of good quality for making of red wines and not always these forms correspond to the morphological description of the variety. The aim of the research is DNA fi ngerprinting of the «Kachich» grape variety based on the analysis of polymorphism of microsatellite loci. The object of the study was the plants corresponding to the variety description, growing in the collection of the agricultural company “Wines and waters of Abkhazia” (Sukhum, Abkhazia). DNA was isolated from the young leaves of the top of the shoot of typical plants of the variety by the CTAB-method. Genotyping was carried out by polymerase chain reaction (PCR) with separation of reaction products by capillary electrophoresis. Highly polymorphic SSR-markers recommended for grapes varieties identifi cation were used for study (VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD28, VVMD32, VrZAG62, VrZAG79). The size of amplifi ed fragments was estimated using the automatic genetic analyzer ABI Prism 3130 and special software GeneMapper and PeakScanner. To clarify the size of amplifi ed fragments, the DNA of reference varieties was used. According to the results of microsatellite analysis, the DNA-certifi cate of the genotype of the «Kachich» grape variety was compiled: VVS2153 155 VVMD5234 240 VVMD7239 249 VVMD25239 267 VVMD27186 193 VVMD28234 248 VVMD32262 272 VrZAG62194 196 VrZAG79236 236. The resulting DNA-profi le was checked for matches in the Vitis International Variety Catalogue VIVC. No matches of the obtained DNA-profi le with any other DNA-profi le presented in the Database were found. DNA-certifi cate of genotype «Kachich» can be successfully used for varieties identifi cation of grape plants if necessary to clarify their varietals affi liation.

AbstractWe study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980 and 1992), can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies (from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments, the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality much more than natural endowments, the effect of which is negligible. (JEL Classification: L66, Q12, Q13, Q16)

Abstract The latest research revealed that phenolic compounds play an important role in the quality of red wine, particularly on colour and astringency and also are responsible for the sanogenic or multiple benefic effects on human health after a moderate consumption of wine. This paper presents the ripening evolution of routine quality control parameters (sugars, acids, weight of 100 berries) and phenolic compounds (anthocyanins and polyphenolic index) during 2013 year for the most representative red grape varieties (Cabernet Sauvignon, Merlot, Feteasca Neagra, Pinot Noir and Mamaia) authorized to obtain wines with denomination of origin controlled in Murfatlar wine center. Also, the phenolic profile of obtained red wines was evaluated by reversedphase high performance liquid chromatography. The reported results were useful to find the optimum moment for grape harvest ensuring the production of high quality wines.

Winemaking processes and volatile compounds perform an important role in contributing to the quality of wines. ‘Marselan’ is a red grape variety grown in several countries such as France, Brazil and China. This variety has gained international interest in recent years. The volatile profile of Brazilian ‘Marselan’ red wines during various winemaking processes was studied. Four processes were applied: thermovinification, integrale vinification, classic winemaking and classic winemaking pretreated with ultrasound. The wines were characterized with conventional physicochemical analyses, volatile composition and sensory analysis. Sixty-three volatile compounds were identified and semi-quantified. The wines presented different sensory characteristics. The thermovinification and classic winemaking with ultrasound application methods showed a large presence of esters contributing to a fruity and overmaturation aroma in the volatile profile and sensory analysis. An increased presence of vegetal and sulfurous aromas was observed in the wines from the classic winemaking and integrale vinification processes. This effect was most likely attributed to the lower influence of esters which generated a greater perception of other compounds and conferred these aromas. The differences can be directly linked to the various extraction rates in the vinification processes, which result in different interactions between the compounds.

Experimental data on the concentration of phenolic compounds in classical Vitis vinifera grapes and hybrid varieties growing in various soil and climatic zones of the Krasnodar Territory are presented. It has been shown that the technological stock of phenolic compounds varies widely – from 5420 to 7360 mg / dm3, depending on the grape variety and the place of its growth. Moreover, in hybrid varieties, the accumulation of the sum of polyphenols is higher than in classical ones. according to the technological stock of PS, the studied varieties can be arranged in the following row: Golubok> Krasnostop anapsky> Harmony> Alkor, Saperavi. On the example of the Cabernet-Sauvignon variety, the influence of the place of grape growth on the technological stock of polyphenols is shown: the largest amount of the phenolic compounds was in the grapes of AF Myskhako, where the highest amount of active temperatures was noted. The farms of Temryuk district obtained close results. The largest amount of resveratrol stilbene, phenolic acids, including chlorogenic, gallic acid, was found in the must of Cabernet-Sauvignon grape variety grown in AF Myskhako and AZOS ViV. The identity of the qualitative composition of the phenolic complex of all investigated grape varieties, including hybrids, has been established. In the studied grape varieties, monomers of flavonoids are represented by anthocyanins, quercetin, (+) - D-catechin, (-) - epicatechin. Among the monomeric non-flavonoids, hydroxy acids were determined, among the oligomeric polyphenols, the oligomeric procyanidins B1, B2, B3, which are condensed derivatives of catechin, were found.
