French heatwave to cut Champagne yields by 10%

France's ongoing heatwave is squeezing grape yields across major wine regions, with Champagne growers bracing for a 10% production drop compared to last year. The heat has also triggered what could be the earliest Champagne harvest on record, starting around mid-August rather than mid-September. Burgundy and Bordeaux are facing even tougher conditions, though producers are hoping for substantial rainfall in the coming weeks to salvage yields.
