The Northern Grapes Project was funded in 2011 by the USDA NIFA Specialty Crops Research Initiative.  The emergence of cold hardy, Vitis riparia-based wine grape cultivars in the 1990s created a new and rapidly expanding industry of small vineyard and winery enterprises in more than 12 states in New England, northern New York, and the Upper Midwest, boosting rural economies in those regions.  Read more.

Itasca grape.

The University of Minnesota recently released its fifth cold-hardy wine grape, named ‘Itasca.’ Itasca arose from a 2002 cross made by Peter Hemstad between Frontenac gris and MN 1243, and was identified in 2009 as an elite seedling.

Data provided by Matthew Clark show that at harvest, titratable acidity in Itasca averages close to 10 g/L, while La Crescent is 14.5 g/L and Frontenac gris is 15.5 g/L. After the Polar Vortex winter of 2014, Itasca had over 60% primary bud survival, while other white cultivars had less (Frontenac gris, 20%: Frontenac blanc, 35%; La Crescent, 30%).

Licensed nurseries will begin selling Itasca in 2017.
