According to the intergovernmental organization, production will reach between 227 and 235 million hectoliters in 29 countries, which account for 85 percent of global production.
With an average production of 231 million hectolitres, it is 2% less than in 2023 and 13% less than the average of the previous 10 years.
"Climate challenges in both hemispheres are again a major contributor to the reduced volume of global production," the OIV report said.
"Preliminary estimates reveal a complex landscape of climatic disturbances in EU wine regions due to climate change. As in 2023, extreme or atypical weather events have a key impact on global production, with early frosts, heavy rains and prolonged drought having a dramatic impact on vineyard productivity," the report added.
Production in France, the biggest producer last year, will fall by 23%, the biggest decline in the sector.
Italy recovered slightly from last year's low volume and regained the top spot ahead of France.
"Only a small group of regions - most notably the United States and several Eastern European countries including Hungary, Georgia and Moldova - enjoyed more favourable climatic conditions, achieving average or above average production volumes," the OIV said. | BGNES
