A Nuremberg court ruled in November that the Lammsbräu company, which specializes in organic beverages including beer, cola, and fruit juice is allowed to add is "Bio" tag to its new mineral water range.
The court has now made two decisions on the case, both times ruling in favour of the company.
But the Frankfurt-based Centre for Protection against Unfair Competition is not satisfied with the verdicts, and has decided to appeal the decision at Germany's Federal Court of Justice.
The case hinges on whether there's a distinction between "organic" mineral water and ordinary mineral water.
Lammsbräu claims there are 50 separate criteria that decide whether water is organic or not, divided into three categories:
– water production that minimizes contaminants
– an environmentally-conscious treatment of the source of the mineral water and its surroundings.
– environmentally-friendly packaging and safe transport that avoids contamination and long distances.
In a statement published on the company's website, Lammsbräu boss Susanne Horn, said: "We will do everything in the interests of the consumer to make sure that organic quality can exist in our most important source of nutrition – water – just as we're accustomed to with all other drinks, whether its apple juice or beer."
