Bottling

Once a natural mineral water has received its official seal of approval, there are explicit rules that regulate bottling:

• Natural mineral water must be bottled directly at the source to guarantee that consumers get water of original, unimpaired purity that is free of contaminants. 
• The bottle cap must indicate whether or not the bottle has remained sealed since bottling. This is for instance ensured by the freshness-seal on aluminum caps or by the safety-ring on caps made of plastic. Naturally all of Gerolsteiner's products are bottled in keeping with these strict specifications.
