Summary

Record heatwaves in France have led to an unusually sweet harvest, resulting in champagne with a higher alcohol content than usual. The National Origin and Quality Institute has authorized an exemption allowing producers to increase the alcohol level from 13% to 15%, which will be the strongest champagne in French history. According to experts, only a few producers will be affected, but some are concerned that the higher alcohol content may deter buyers. Champagne bottles made with this stronger blend won't hit shelves until at least 2028 due to fermentation requirements.

Story summary

A record heatwave in France has led to an unusual decision by the National Origin and Quality Institute to allow some champagne producers to increase their alcohol content from 13% to 15%, which is expected to result in a stronger drink. This exemption was granted due to the extreme weather conditions, with 2026 being the hottest summer on record** in France. Climate change experts warn that such events will become more frequent and intense in the future. Some producers are concerned that the higher alcohol content may be off-putting for buyers, who have been trending towards lower-alcohol wines in recent years. Stéphane Vignon, a producer based in Verzenay, suggested that some champagne makers might mitigate the effects of the increased alcohol by mixing their batches with older vintages. The change is only expected to affect a few producers, but it has prompted concerns about the future of champagne production under climate change.
