Key facts
- French champagne producers can now produce bubbly with up to 15% alcohol content, an increase from the previous 13% cap.
- Record heatwaves and drought in France led to grapes with exceptionally high sugar levels.
- The Champagne region experienced its earliest-ever harvest, beginning in early August.
- The temporary increase in alcohol content is expected to affect only a small number of wines from this harvest.
- The 2026 vintage is unlikely to be available until 2028 due to the required aging period.
Record heatwaves in France have prompted regulators to allow champagne producers to temporarily increase the alcohol content of their bubbly to 15%, up from the usual 13% cap. The extreme weather conditions this summer resulted in grapes with unusually high sugar levels, which yeast converts into alcohol during fermentation. This phenomenon, coupled with the earliest harvest on record in the Champagne region, has led to this exceptional measure.
According to the Comite Champagne industry association, the decision to raise the limit was made because a small number of wines from this harvest could have slightly exceeded the 13% regulatory limit, reaching around 13.1% or 13.2%. The temporary increase is only for this year's production.
Producers noted that the Mediterranean climate is shifting northward, suggesting that such early harvests due to heatwaves might become more common in the next 10 to 15 years. However, wine experts caution that higher-alcohol champagne may not appeal to consumers who increasingly prefer lower-alcohol options. The 2026 vintage will not reach shelves until 2028, as champagne requires at least 15 months of aging.
