Champagne producers granted exception for higher alcohol content amid heatwaves

Extreme weather conditions in France have led to a historic shift for the Champagne region. Due to intense spring frosts, early flowering, and multiple summer heatwaves, the 2026 harvest was recorded as the earliest on file, with widespread harvesting beginning by August 17.

To manage the impact of these climate conditions, the Comité Champagne obtained a temporary derogation from the INAO, allowing producers to market bottles with an alcohol content of up to 15 percent, a significant increase from the usual 13 percent limit. This change responds to the high sugar buildup in grapes caused by extreme heat.

While the harvest shows high potential for producing exceptional wines, yields have dropped significantly. The agronomic yield reached approximately 7,000 kg per hectare, a nearly 30 percent decrease from the 9,900 kg per hectare recorded in 2025. Industry officials noted that such unusual harvests may become the norm within 10 to 15 years due to climate change.
