Winery loses 80 percent of its red grapes during late-season freeze

PRAIRIE DU SAC, Wis. – Philippe Coquard was up all night in his vineyard Saturday night into Sunday morning. He tried moving the cold air around and away from the grapes, but it was no use. “When it came that fast, that drastically, the temperature went from 31 to 27 in four hours. There’s nothing that you can do to fight that,” Coquard said.
