Highest Product Quality from Source to Bottle - Continuously Controlled

No German food product is better controlled than Natural Mineral Water, the only food product with an offical recognition.


As a completely natural product, Steinsieker must fulfill the stringent legal requirements of the German Mineral Water and Table Water Regulation (MTVO). Before achieving the official title of “Natural Mineral Water” more than 200 tests are necessary. The standards are continuously monitored by the German food authorities.


Steinsieker is IFS (International Food Standard) certificated.

There is regular testing from Steinsieker’s spring to the bottle. Samples are continuously taken during the filling process and are analysed in Steinsieker’s in-house laboratory. Retention samples of every filling are stored. Additionally, independent external laboratories conduct regular control analysis tests.


The safety ring of the cap indicates that the bottle is originally sealed at source.


Steinsieker ensures consistent product quality and product security from source to bottle.
