French Champagne Houses Increase Alcohol Content Following Heatwave Harvest

Winemakers in France's Champagne region are producing sparkling wine with a higher alcohol content than previous years, reaching up to 15% ABV. This shift follows the 2023 harvest, which saw grapes ripen to an exceptional sweetness due to record heatwaves across the country.

Historically, Champagne has maintained an alcohol by volume (ABV) of around 12.5%. The recent climate conditions, however, have led to grapes containing higher sugar levels, which convert into more alcohol during fermentation. This phenomenon has prompted producers to adapt their processes.

While some winemakers are embracing the stronger product, others face the challenge of maintaining the traditional balance and character of Champagne. The long-term implications of these warmer vintages on the industry's practices and product profile are yet to be fully understood, as climate change continues to impact agricultural yields in key European wine-growing regions.
