St. Gero Mineral Water

St. Gero is a premium German mineral water brand known for its naturally high content of minerals like calcium, magnesium, and hydrogen carbonate. It is a 'Säuerling' (acidulous) water bottled directly at the source in the Vulkaneifel region. The brand is deeply rooted in German tradition and the health-conscious sparkling water market.

The product is manufactured and bottled in Gerolstein, Germany. The brand is part of the Gerolsteiner Brunnen company, which is the leading exporter of mineral water in Germany. Ownership belongs to the Bitburger Holding, a major German family-owned enterprise prominent in the brewery and beverage industry. The water is sourced from the volcanic rock layers of the Eifel mountains, ensuring a unique mineral composition that is preserved through strict local bottling processes.
