French wine production will fall 12% this year after vines were damaged by spring frosts, drought and hail, but quality will remain generally good, the agriculture ministry said on Tuesday.
In its second estimate for 2019, the ministry forecast production of 43.4 million hectolitres, down from 49.4 million in 2018 when output had benefited from good weather condition.
Last month the farm ministry put French output in 2019 in a range of 42.8 million to 46.4 million hectolitres.
A hectolitre (100 litres) is the equivalent of about 133 standard wine bottles.
In many vineyards, flowering occurred in rainy and cold weather, while heat and hail have also contributed to a decline in production potential, the ministry said in a note.
However, the situation will vary by region.
Record-breaking heatwaves in June and July affected some regions in the south, such as the Gard, Herault or Var, causing burns on the grapes and production losses, it said.
