Sourced from a deep aquifer, natural mineral waters are from unpolluted aqueous systems of original, natural, chemical composition, and existing exclusively due to phenomena of interactions between water and rock.  For this reason, this chemical composition is unique, with no two waters being equal, and is a defined chemical standard which has passed unchanged down through the years.

The commercial use of a natural mineral water is duly regulated in Portuguese legislation, and requires authorisation by the Directorate General for Energy and Ecology, once approved by the Directorate General for Health, and once evidence has shown that the hydromineral resource meets all requirements of the definition of mineral water as set by the European Union.
