2019 Grape Maturity at OSU Research Vineyards Imed Dami, Diane Kinney, Andy Kirk, Yvonne Woodworth, the Ohio State University
OHIO AGRICULTURAL RESEARCH AND DEVELOPMENT CENTER 2019 Grape Maturity at OSU Research Vineyards Imed Dami, Diane Kinney, Andy Kirk, Yvonne Woodworth, The Ohio State University. Thanks to the continuous interest by Ohio growers and vintners and support by the Ohio Grape Industries Committee, we are pleased to resume monitoring fruit maturity progression of varieties grown at the research vineyards during the 2019 season. This information will be sent weekly to OGEN subscribers and posted on the program website, Buckeye Appellation. The date of berry sampling and corresponding heat units or growing degree days (GDD) are included. Note that the GDD in your location could be higher or lower than that at our sites. For example, at the Wooster research vineyard, grape ripening of similar varieties is typically 1 to 2 weeks behind central and southern Ohio, and 1 to 2 weeks ahead of more northern latitude vineyards and on Lake Erie shores. To determine the GDD in your location, visit the OSU-GDD Calculator. To learn more about monitoring fruit maturity and berry sampling, please read OSU factsheet at the following link: Are your grapes ready to pick? Click here for Fruit maturity from previous years.

Phenolic Compounds As Markers of Wine Quality and Authenticity
foods Review Phenolic Compounds as Markers of Wine Quality and Authenticity Vakare˙ Merkyte˙ 1,2 , Edoardo Longo 1,2,* , Giulia Windisch 1,2 and Emanuele Boselli 1,2 1 Faculty of Science and Technology, Free University of Bozen-Bolzano, Piazza Università 5, 39100 Bozen-Bolzano, Italy; [email protected] (V.M.); [email protected] (G.W.); [email protected] (E.B.) 2 Oenolab, NOI Techpark South Tyrol, Via A. 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. -
Matching Grape Varieties to Sites Are Hybrid Varieties Right for Oklahoma?
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 -

Chemical Characteristics of Wine Made by Disease Tolerant Varieties
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. -

1 GRAPE DISEASE CONTROL, 2015 After a 1-Year Hiatus, It's Time Once
GRAPE DISEASE CONTROL, 2015 Wayne F. Wilcox, Department of Plant Pathology, Cornell University, NY State Agricultural Experiment Station, Geneva NY 14456 ([email protected]) After a 1-year hiatus, it’s time once again for the (almost) annual update and review on controlling the fungal diseases that grape growers must regularly contend with in our eastern climate. As always, I’d like to acknowledge the outstanding team of grape pathologists here in Geneva, which includes bacteriologists (Tom Burr’s program) and virologists (Marc Fuchs’s program) in addition to those of us who work on fungal diseases: faculty colleagues and cooperators (David Gadoury, Bob Seem, Lance-Cadle-Davidson); research technicians (including the phoenix-like Duane Riegel, Dave Combs, and Judy Burr); and graduate students and post-docs too numerous to mention here. It truly is the combined research efforts of all of these people that serve as the basis for most of the following. THE WINTER FROM HELL We won’t dwell upon it, but there are going to be some consequences this coming season as a result of our recently-concluded (or so it’s starting to appear) WFH. It’s beyond the scope of this screed to discuss and sometimes lament many of the more obvious issues, but there are a couple of disease-related points that are worth covering briefly: • Phomopsis infection of new suckers. This issue falls into the “observation/speculation” category rather than one that contains relatively well-established facts. That being said, the last time (2004) that upstate NY had winter temperatures that killed top wood in a significant number of locations, I (and others) noticed that sucker growth destined to become new trunks developed an awful lot of Phomopsis infection during the early growing season. -

Within a range of research topics, steep slope viticulture is still a major focus at the University of Geisenheim. We will discuss various aspects of consumer´s recognition, viticultural constraints in terms of climatic adaptations (water requirements, training system or fruit composition) as well as innovations in mechanisation in the context of future challenges of steep slope viticulture. -
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.
