  • 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.

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.

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.

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.
