Hugo, Minn. – It’s common knowledge that it gets cold-very cold- in Minnesota every year, and not just during winters with unusual polar vortexes. Yet wild grapes such as Vitis riparia survive temperatures that drop to -30 oF and lower without suffering from dead buds and split trunks. The challenge to growers has been to breed new varieties with resistance to extreme cold as well as the ability to produce grapes that can be made into high-quality wines.
