A great deal of research has been conducted to characterize the ripening profiles of Vitis vinifera <\/em>cultivars, which helps growers make informed decisions regarding harvest. However, little is known about the changes in chemical composition during ripening of the cold hardy cultivars.<\/p>\n Recent work at the University of Minnesota tracked changes in fruit composition of 11 cultivars, including seven cold hardy cultivars. The results are a good start to understanding more about the changes that occur in fruit chemistry as berries ripen. Included in this months\u2019 News You Can Use<\/em> are two publications that summarize this work; the first is \u201cUnderstanding the Ripening Chemistry of Cold-Hardy Wine Grapes to Predict Optimal Harvest Time,<\/a>\u201d an article originally published in the August 2012 issue of Northern Grapes News. <\/em>The second is \u201cFruit Ripening Profiles of Cold Climate Wine Grape Cultivars,\u201d<\/a> a research report that was written as part of the Year 2 Northern Grapes Progress Report.<\/p>\n Additional Resources:<\/strong><\/p>\n Fruit Maturity Evaluation of Wine Grapes for Harvest Planning (http:\/\/www.extension.org\/pages\/33152\/fruit-maturity-evaluation-of-wine-grapes-for-harvest-planning#.U9Kx2PldWJc<\/a>)<\/p>\n (http:\/\/www.extension.org\/pages\/33154\/collecting-berry-samples-to-assess-grape-maturity#.U9Kz7vldWJc<\/a>)<\/p>\n Using a Refractometer to Measure the Sugar Concentration of Sap and Syrup (http:\/\/maple.dnr.cornell.edu\/kids\/refractometer.htm<\/a>)<\/p>\n Chrislyn A.
