French Court Allows Perrier to Continue Sales as 'Natural Mineral Water' Despite Consumer Group Challenge

On November 18, 2025, the Nanterre judicial court ruled in favor of Nestlé Waters, allowing the continued sale of Perrier sparkling water labeled as "natural mineral water" in France. This decision came despite a legal challenge by the consumer association UFC-Que Choisir, which had sought to suspend sales, arguing that Perrier's use of filtration processes disqualified it from the "natural mineral water" designation and misled consumers about product purity. UFC-Que Choisir had filed its complaint on June 5, citing revelations concerning the use of microfiltration practices that allegedly compromise the water's natural qualities.

Nestlé Waters responded by asserting the safety of its products, stating that all waters are fit for consumption. The company had previously used banned treatments but replaced them with a legal microfiltration system, which remains controversial as health authorities have noted it alters the water's microbial profile, requiring subsequent adjustments. Despite the ongoing dispute and a decline in certain Perrier product outputs, such as the blue bottle line due to halted drilling, sales of Perrier's standard bottles remain stable.

The UFC-Que Choisir lawyer stressed the importance of water sold as natural being pure and unprocessed, while competitors have advocated rigor around "natural mineral water" labeling integrity. However, the court found no proven health risk or legal basis to suspend Perrier sales, allowing Nestlé to continue marketing under its current designation in the French market. This ruling represents a significant moment in French consumer protection and food regulations regarding bottled water labeling.
