Fine-Tuning Grapes For Iowa’s Wine Industry

Did you know that almost all the wine we drink, no matter what color it is or where it’s produced, comes from a grape species called Vitis vinifera? But these grapes can’t survive the cold, harsh winters of Iowa, so researchers at Iowa State University are growing special varieties that can withstand a wider range of temperatures. Through this effort, they’re even hoping to expand Iowa’s wine industry.Onstage in Ames, Iowa, Ira talks with Dr. Erin Norton, director of the Midwest Grape and Wine Industry Institute at Iowa State University. They chat about the science of growing cold-hardy grapes, taste a selection of Iowan wines, and explore the basics of viticulture.Transcripts for each segment will be available after the show airs on sciencefriday.com.
