Volta 13B, 39100 Bozen-Bolzano, Italy * Correspondence: [email protected]; Tel.: +39-0471-017691 Received: 29 October 2020; Accepted: 28 November 2020; Published: 1 December 2020 Abstract: Targeted and untargeted determinations are being currently applied to different classes of natural phenolics to develop an integrated approach aimed at ensuring compliance to regulatory prescriptions related to specific quality parameters of wine production. The regulations are particularly severe for wine and include various aspects of the viticulture practices and winemaking techniques. Nevertheless, the use of phenolic profiles for quality control is still fragmented and incomplete, even if they are a promising tool for quality evaluation. Only a few methods have been already validated and widely applied, and an integrated approach is in fact still missing because of the complex dependence of the chemical profile of wine on many viticultural and enological factors, which have not been clarified yet. For example, there is a lack of studies about the phenolic composition in relation to the wine authenticity of white and especially rosé wines. This review is a bibliographic account on the approaches based on phenolic species that have been developed for the evaluation of wine quality and frauds, from the grape varieties (of V. -

Owing to the superior quality of their grapes, these cultivars were long considered the only suitable for the production of high quality wines. However, the lack of resistance genes to fungal diseases like powdery and downy mildew (Uncinula necator and Plasmopara viticola) makes it necessary the application of huge amounts of chemical products in vineyard. Thus, the search for alternative and more sustainable methods to control the major grapevine pathogens have increased the interest in new disease tolerant varieties. Chemical characterisation of these varieties is an important prerequisite to evaluate and promote their use on the global wine market. The aim of this project was to produce a comprehensive study of some promising new disease tolerant varieties recently introduced to the cultivation by identifying the peculiar aspects of their composition and measuring their positive and negative quality traits. -

Received: 21 July 2020; Accepted: 8 August 2020; Published: 12 August 2020 Abstract: The Swedish wine industry has exponentially grown in the last decade. However, Swedish wines remain largely unknown internationally. In this study, the typicality and sensory space of a set of twelve wines, including five Swedish Solaris wines, was evaluated blind by Swedish wine experts. The aim of the work was to evaluate whether the Swedish wine experts have a common concept of what a typical Solaris wines should smell and taste like or not and, also, to bring out more information about the sensory space and chemical composition of Solaris wines. The results showed a lack of agreement among the wine experts regarding the typicality of Solaris wines. This, together with the results from the sensory evaluation, could suggest the possibility of different wine styles for Solaris wines. -
Solaris – the New Grape Variety for Sylt
Solaris – The New Grape Variety for Sylt An ideal grape variety for Sylt – according to Professor Dr. Löhnertz of the oenological research institute in Geisenheim/Rheingau – would ripen early to mid-early; have flowering firmness; and have loosely- packed clusters. These are, among others, the traits of the white grape variety Solaris, which was bred by Norbert Becker in 1975 at the State Viticultural Institute in Freiburg/Baden. It is a crossing of Merzling x GM 6493. The latter (Gm = Geisenheim) was originally part of a seedling population that Professor V. Kraus crossed in 1964, from the varietals Zarya Severa and Muskat-Ottonel in (then) Czechoslovakia. Solaris has large, three-lobed, dark green leaves. Its grapes are medium large. Budburst, blossoming and véraison (onset of ripening) all take place about a week earlier compared with traditional grape varieties. Solaris is also frost-resistant. It is not particularly demanding in terms of site since grape musts usually reach 100 degrees Oechsle by the beginning of September. Furthermore, Solaris is not very vulnerable to fungal disease and it brings forth a good-sized crop. The grape received varietal protection in 2001 and was added to the official grape registry in 2004. As of late April 2009, there were 59 ha (146 acres) of Solaris planted in Germany. Its name derives from sol , Latin for sun, and literally means “of the sun.” Up until now, Solaris has been cultivated primarily in the German wine-growing region Baden (Markgräflerland) and in the Swiss canton Zürich (Winterthur). There are also a few plantings in Denmark. -

The Grapevine Vvibzipc22 Transcription Factor Is Involved in the Regulation of Flavonoid Biosynthesis

Their synthesis in many plant species is mainly regulated at the transcrip- tional level by modulation of flavonoid pathway genes either by single regulators or by complexes of different regu- lators. In particular, bZIP and MYB factors interact synergistically in the recognition of light response units present in the promoter of some genes of the pathway, thus mediating light-dependent flavonoid biosynthesis. We recently identified VvibZIPC22, a member of clade C of the grapevine bZIP family, in a quantitative trait locus (QTL) specifi- cally associated with kaemperol content in mature berries.
