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.

  • CHARDONEL – Still Wine Styles
    CHARDONEL – Still Wine Styles MEETING NOTICE The topic for our January meeting is "Chardonel Still Wine Styles". Fifty-nine wineries in Missouri produce wine using the Chardonel grape (1) , making it one of the most popular regional wines. Amateur wine makers in Missouri are fortunate that high quality Chardonel grapes are available from local vineyards. Steve Brunkhorst will lead the meeting, and will share his 2014 vintage Chardonel wines. We will taste his Chardonel produced in glass without flavor or aroma modification, and compare it to the same base wine produced with malolactic fermentation as well the same base wine aged with American oak. We will also taste Chardonel wines from several Missouri wineries.

    Matching Grape Varieties to Sites Are hybrid varieties right for Oklahoma? Bruce Bordelon Purdue University Wine Grape Team 2014 Oklahoma Grape Growers Workshop 2006 survey of grape varieties in Oklahoma: Vinifera 80%. Hybrids 15% American 7% Muscadines 1% Profiles and Challenges…continued… • V. vinifera cultivars are the most widely grown in Oklahoma…; however, observation and research has shown most European cultivars to be highly susceptible to cold damage. • More research needs to be conducted to elicit where European cultivars will do best in Oklahoma. • French-American hybrids are good alternatives due to their better cold tolerance, but have not been embraced by Oklahoma grape growers... Reasons for this bias likely include hybrid cultivars being perceived as lower quality than European cultivars, lack of knowledge of available hybrid cultivars, personal preference, and misinformation. Profiles and Challenges…continued… • The unpredictable continental climate of Oklahoma is one of the foremost obstacles for potential grape growers. • It is essential that appropriate site selection be done prior to planting. • Many locations in Oklahoma are unsuitable for most grapes, including hybrids and American grapes. • Growing grapes in Oklahoma is a risky endeavor and minimization of potential loss by consideration of cultivar and environmental interactions is paramount to ensure long-term success. • There are areas where some European cultivars may succeed. • Many hybrid and American grapes are better suited for most areas of Oklahoma than

They are grown in home gardens for fruit and landscape the lives of New purposes or commercially for wine, raisins, or fresh consumption as “table” grapes. A cultivated variety, or “cultivar,” is a formal term for Mexicans through variety. Variety is the more common term, and will be used in this publication. Selecting grape varieties that are adapted to prevailing academic, research, climatic and soil conditions is an important step before planting. Very few locations above 6,000 feet in elevation are successful grape pro- and Extension duction sites. Suitable growing conditions at lower elevations are still very site-specific due to the major threat to grape culture: winter or programs. frost injury. Winter injury occurs at subfreezing temperatures during vine dormancy when no green tissue is present. Frost injury occurs at subfreezing temperatures when green tissue is present. A variety’s win- ter hardiness, or ability to withstand cold temperatures, depends on its genetic makeup or “type.” In addition to winter hardiness, other considerations when selecting a variety are its fruit characteristics, number of frost-free days required for ripening, disease susceptibility, yield potential, growth habit, and other cultural requirements.

    UNIVERSITÀ DEGLI STUDI DI UDINE in agreement with FONDAZIONE EDMUND MACH PhD School in Agricultural Science and Biotechnology Cycle XXX Doctoral Thesis Chemical characteristics of wine made by disease tolerant varieties PhD Candidate Supervisor Silvia Ruocco Dr. Urska Vrhovsek Co-Supervisor Prof. Doris Rauhut DEFENCE YEAR 2018 To the best gift that life gave us: to you Nonna Rosa CONTENTS Abstract 1 Aim of the PhD project 2 Chapter 1 Introduction 3 Preface to Chapter 2 17 Chapter 2 The metabolomic profile of red non-V. vinifera genotypes 19 Preface to Chapter 3 and 4 50 Chapter 3 Study of the composition of grape from disease tolerant varieties 56 Chapter 4 Investigation of volatile and non-volatile compounds of wine 79 produced by disease tolerant varieties Concluding remarks 140 Summary of PhD experiences 141 Acknowledgements 142 Abstract Vitis vinifera L. is the most widely cultivated Vitis species around the world which includes a great number of cultivars. 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.

  • Wine Grape Variety Trial for Maritime Western Washington 2000-2008
    Summary of Results: Wine Grape Variety Trial for Maritime Western Washington 2000-2008 Wine Grape Cultivar Trials 2000-2008 in the Cool Maritime Climate of Western WA Gary Moulton, Carol Miles, Jacqueline King, and Charla Echlin WSU Mount Vernon NWREC 16650 State Route 536, Mount Vernon, WA 98273 Tel. 360-848-6150 Email [email protected] http://extension.wsu.edu/maritimefruit/Pages/default.aspx Wines produced from grapes grown in cool climate regions have generally low alcohol content, low viscosity, and high fruit aromas and flavor (Casteel, 1992; Jackson and Schuster, 1977; Zoecklein, 1998). Certain varietals from Germany, Austria Russia, Hungary, and Armenia, as well as some common French varieties such as Pinot Noir and Pinot Gris can produce excellent fruity wines in western Washington. Selection of the right clone is important and knowing the heat units of your site will greatly aid in the selection of which varieties to grow. The cool maritime region of western Washington is on the very low end of the spectrum with respect to the number of growing degree days (GDD) needed for ripening the more common wine grape cultivars. Although the Puget Sound region has a long growing season in terms of frost free days, mesoclimates within the area range from below 1200 GDD to 2200 GDD. The Washington State University Mount Vernon Northwestern Washington Research and Extension Center (WSU Mount Vernon NWREC) research site is located at 12 feet above sea level in the Skagit Valley floodplain, 3 miles from the Puget Sound. Since 2002, annual GDD averaged 1693; in 2003 there was a spike in GDD of 1965.
