Gerolsteiner - Natural water from the Volcanic Eifel.
Due to the Volcanic Eifelís geological history, Gerolsteiner mineral water is especially rich in minerals. Water that has gathered through the decades is taken from the depths. Every drop of rain is filtered and purified on its way through the various layers of rock. At the same time, the water is enriched with carbonic acid. Aided by the carbonic acid, the drop of water is able to assimilate minerals and trace elements from the otherwise non-water-soluble dolomite rock. Carbonic acid is also to thank for the water staying fresh and clear throughout the centuries.
The origins lie in the depths
The mineral water gathers in layers of rock located up to 200 meters beneath the surface, and is thus safe from environmental influences. It is pumped to the surface from 21 wells in Gerolstein and subsequently piped to the bottling facilities in Gerolstein. These pumping stations are electronically supervised to continuously control the wells' water level, the temperature and the mineral level.
