Iowa has experienced a tremendous increase in commercial grape plantings in recent years, and the interest in establishing additional plantings continues to increase. However, as new plantings are planned, new cultivars can only be recommended with reservation until they are thoroughly tested under Iowa’s climatic conditions. Through an Iowa Department of Agriculture and Land Stewardship (IDALS) specialty crops grant awarded to the Iowa Grape Growers Association (IGGA) and contracted to the ISU Department of Horticulture, a wine grape cultivar trial was established in 2003 to evaluate the adaptability, productivity, and wine making quality of 20 new cultivars.
