Production of mineral water

From the source to the consumer

Valuable minerals, refreshing taste and purity: All carefully preserved so what Nature produces deep in the earth remains unaltered when bottled for you. Gerolsteiner arrives just as fresh and pristine to you as when it’s collected from the depths of the Volcanic Eifel. To guarantee this, each individual production step is monitored – from the source to filling the bottles – by qualified staff and with the help of the latest technology. Chemical analyses and microbiological investigations take place as part of product control. As natural mineral water, Gerolsteiner water is among the most strictly controlled foodstuffs, in accordance with the Mineral and Table Water Ordinance (MTVO) of Germany.

Germany’s most popular natural mineral water comes from Gerolstein in the heart of the Volcanic Eifel, hence it’s name: Gerolsteiner. Mineral water is one of nature’s precious miracles. It is formed over many decades from rainwater, which is purified and filtered by slowly trickling through layers of bedrock, all the time absorbing valuable carbonic acid and minerals.

Each step of the production process is closely monitored to ensure the water’s purity. The aim of Hazard Analysis Critical Control Points (HACCP) analysis is to ensure quality and safety throughout production, packaging and the sale of foods and beverages. Critical control points (CCP) identified by the analyses are monitored continuously and the tests are documented.

Gerolsteiner has always claimed that the best products also deserve to be supported by the best technology. Whether it’s the development of innovative packaging, selection of materials, perfection of product safety or bottling technology – Gerolsteiner always aims to find the best solution.
