(AP) — In a vineyard in Moravia, the Arctic chill striking Europe at least has some people jumping with joy. Winemakers in southeast Czech Republic, waiting for a dip in temperatures during an unusually warm winter, finally got the deep chill they needed to harvest grapes for the most prestigious part of their business — ice wine. The sense of relief was palpable after temperatures finally dropped to minus 7 Celsius (19 Fahrenheit), allowing grapes to be picked for the sweet, expensive wine. Strict government regulations are in place saying the grapes for ice wine can't be picked until the mercury drops to that level.
