In conjunction with the Northeast Regional Research project NE 1020 “Multi-state Evaluation of Wine Grape Cultivars and Clones,” Iowa State University established a cold hardy wine grape cultivar trial in 2008 at the ISU Horticulture Research Station (HRS) and Tabor Home Vineyards and Winery (THV) near Baldwin, IA. The Iowa trial evaluates the performance of Corot noir, La Crescent, Marquette, Petit Amie, NY 95.0301- 01, MN-1189, MN-1200, MN-1220, MN- 1235, MN-1258, with Frontenac and St. Croix serving as controls. Similar plantings were established in SD, NE, and MO, as well as in CT, IN, KY, and MI. This report summarizes the results for the 2010 growing season.
