Spring frost has ravaged production in some of France's most famous winemaking regions, including Champagne, Bordeaux, and Burgundy,
causing at least €1 billion in damage in what vintners call the biggest disaster in a quarter century.Temperatures plunged below freezing in late April, hurting shoots already well-developed because of earlier mild weather.
Winegrowers have used candles, heaters and even the down-draft from helicopters to try to save crops.
"It's a frost like we haven't seen since 1991," Paul-Francois Vranken, chief executive officer of Vranken-Pommery Monopole told Bloomberg, adding that winemakers "are worried."
April's frost damage spread across Europe's wine-producing regions, but France was worst affected.
According to the Bordeaux wine federation FGVB, frost affected as much as 60 percent of the Bordeaux wine-growing areas and will cut the volume of the 2017 vintage by as much as 40 percent. Some Bordeaux chateaus say they lost almost everything.
