The firm is well known for its Gerolsteiner Sprudel brand, a bottled, naturally carbonated mineral water.

[1] The first exports of Gerolsteiner to the United States started in 1890, primarily to Chicago, known for its high concentration of German emigrants.

In 1986, Gerolsteiner introduced a brand with a lower amount of carbonic acid to meet changing tastes.

In 1998, the company introduced Germany's first PET reusable deposit carrying mineral water bottle to a chorus of criticism from environmental groups.

[3] The use of returnable, deposit-bearing glass bottles for water, beer, and other mainstream drinks has long been normal in Germany and other European countries.
