What must be true about water sourced in places like Germany to qualify as true mineral water?
Answer
It must be sourced from underground reservoirs with a stable, defined mineral composition
The designation 'true mineral water' in many European contexts, particularly exemplified by standards in Germany, is highly regulated. The water must originate from specific underground reservoirs where it has acquired a stable and defined mineral composition. This requirement ensures that the fundamental characteristics, including the content of key elements like calcium or sodium, remain consistent from the source. This structural definition differentiates it from standard bottled water or water that has been artificially mineralized post-source.
