In 2025, despite a slight increase in wine production compared to the previous year, volumes remain below average levels for the third consecutive year. According to Reuters, citing data from the International Organization of Vine and Wine (OIV), this decline is linked to climate change. Vineyards are experiencing the effects of unstable and extreme weather conditions. According to preliminary estimates by the OIV, global wine production this year is expected to reach 232 million hectoliters, which is three percent higher than in 2024, but seven percent lower than the average over the past five years.
OIV Director General John Barker noted that adverse climate conditions are affecting both the northern and southern hemispheres. Some regions have experienced severe droughts and high temperatures, followed by heavy rains and unexpected frosts.
In France, the harvest was the lowest since 1957, while in Spain, production fell to a 30-year low. However, Italy managed to strengthen its position by increasing output by eight percent and regaining its status as the world's largest wine producer.
