What is the difference between natural mineral water and other types of water?
For a mineral water to be called natural mineral water, it must contain at least 1000 mg dissolved solid substances or 250 mg carbonic acid per litre, and/or a scientist must confirm nutrition-physiological positive effects due to the composition of the water. In addition, it must meet the food codex regulations which conform to EU standards, relating to micro-biological and chemical purity, as well as strong geological and physical requirements.
