283: Developing Cold-Hardy Grapes with 23andMe Technology

from Sustainable Winegrowing Hosted by Vineyard Team

Most of the world's wine grapes, like Chardonnay, Merlot, and Sauvignon Blanc, come from Vitis vinifera, a species prized for fruit quality but highly vulnerable to cold, pests, and disease. Assistant Professor Soon Li Teh of the University of Minnesota is developing new cold-hardy cultivars by combining traditional breeding with DNA technology—essentially 23andMe for grapes. His work taps into the resilience of native American species to improve winter survival and disease resistance. But it's no quick fix: the process from initial cross to cultivar release takes 18 to 25 years.
