(Wines&Vines) - The fears of many growers in the central United States came true as the record high March temperatures that kicked off early bud break were followed by icy weather. Gene Sigel, who owns South River Vineyard winery in Ohio’s Grand River Valley, said there is some frost damage every spring. However, Sigel said that because of elevation or air drainage, some vineyards have not suffered frost damage in his 20 years of growing experience—nor in the past century, according to local lore. Yet even some of those vineyards were damaged. “It really has been a once-in-a-century frost,” Sigel said.
