The preliminary report released today by the OIV estimates global wine production to be between 228 and 235 million hectoliters (Mhl), marking a 3% increase compared to the historically low harvests of 2024, but still 7% below the average of the past five years.
Portugal ranks fifth in Europe and 11th globally, with a projected production of 6.2 Mhl, an 11% decrease from 2024 and a 12% drop over five years.
Experts attributed this decline to the dry Portuguese winter, followed by record rains at the onset of spring, further exacerbated by successive heatwaves during the last summer.
Italy remains the world’s largest wine producer, with an estimated output of 47.4 Mhl, up 8% from 2024, followed by France (35.9 Mhl, -1%), and Spain (29.4 Mhl, -6%).
If confirmed, France’s production volume for 2025 will be the lowest since 1957 (32.5 Mhl), a time when the country was the world leader.
Elsewhere, the United States, Australia, and Argentina maintain their dominant positions in the Americas and the Southern Hemisphere alongside the European giants.
The ongoing global production decline is explained by experts as a result of extreme weather conditions, including heatwaves, droughts, wildfires, early frosts, and occasionally excessive rainfall, according to wine producers.
The OIV has 51 member states engaged in the production and consumption of wine and grapes, representing 90% of the world’s vineyard areas and 75% of global wine consumption.
