The cold snap that hit France last week caused Burgundy winegrowers to fear the worst, given the devastating effect of frost on their vines.
Under threat was the famous Chablis vineyards, where last year the crop was devastated by unseasonal rain and frost in April, followed by hail in June.
After facing a first wave of frost on Tuesday night, Thursday night the winegrowers used several protection systems to protect the vines from the severe cold.
Some sprinkling devices were activated from 11pm. But more spectacular by far was the lighting of hundreds of small, oil-burning heaters across hectares of vines to limit the effects of the frost.
