The water quality in Spain is better than many believe.
Spain is one of the largest mineral water consumers in the world, and despite the size of its home market, its great mineral waters are hardly known beyond national borders. Spain has three important mineral water regions, each with different flavours and traditions.
There is no doubt that the Spaniards take their mineral water very seriously. The characteristics of the individual waters often lead to heated debates, so it is nothing special to discuss mineral water like a good wine.
In Spain, mineral water is mainly drunk without carbonic acid, which is low in sodium and only slightly mineralized.
