The world’s second-largest wine producer after Italy is likely to see production drop between 24 and 30 percent in 2021, taking it to a “historically low” level, the ministry said.
It is already certain to fall below output seen in 1991 and 2017, the two most recent years of disastrous harvests, which followed bouts of late frost.
“For now, it looks like the yield will be comparable to that of 1977, a year when the the vine harvest was reduced by both destructive frost and summer downpours,” the ministry said, raising concerns that this year’s harvest could be the worst on record.
Several nights of frost in early April caused some of the worst damage in decades to crops and vines across the country, including its best-known and
prestigious wine-producing regions from Bordeaux to Burgundy and the Rhône valley to Champagne.
Overall output, also affected by an onslaught of mildew prompted by heavy summer rains, is projected to come at in between 32.6 and 35.6 million hectolitres, the ministry said. A hectolitre is the equivalent of 100 litres, or 133 standard wine bottles.
The 2020 wine harvest was around 45 million hectolitres, the Agriculture Ministry announced last September. That had followed a mild winter and the second warmest Spring in 120 years.

As well as wine producers, growers of kiwis, apricots, apples and other fruit have been badly hit along with farmers of other crops such as beet and rapeseed.
Apricot production is headed for its worst year in more than four decades, the ministry said, falling by half from its average seen over the previous five years.
Agriculture Minister Julien Denormandie has called the frost attack “probably the greatest agricultural catastrophe of the beginning of the 21st century”.
Some scientists say that climate change has sharply increased the odds of such events happening again.
World Weather Attribution, an international organisation that analyses the link between extreme weather events and global warming, said in a study in June that a warmer climate had increased the probability of an extreme frost coinciding with a growing period by 60 percent.
