Late frosts devastate Champagne vineyards, threatening 2024 harvest

Champagne’s vineyards have suffered heavy losses after a series of late frosts in March and April. Nearly 40% of grapevine buds were destroyed, raising concerns about this year’s harvest. Producers now face a critical few weeks as further cold snaps could worsen the damage. Three nights of extreme cold—March 15, March 26, and April 2—hit the region hard. Temperatures dropped to –5°C in places, followed by rain during the day. The Côte des Bar area in Aube and the Marne Valley, covering western Marne and southern Aisne, were among the worst affected.

Despite the damage, experts say the loss of buds may not lead to an equal drop in yield. Pinot Noir and Meunier grapevines can grow secondary shoots to make up for lost buds. Yet the next few weeks, especially mid-May, remain vital as frost risks persist. Growers have tried using heaters to protect vines, but the most reliable backup is the *réserve interprofessionnelle* system. This shared stockpile helps producers manage shortages in difficult years.

The frost has already wiped out 38% of buds, but secondary growth could soften the blow. Champagne’s reserve system will play a key role if yields fall short. For now, the industry watches the weather, hoping for a stable end to spring.
