The best-known mineral water from Spain, Vichy Catalan has very high mineral content, natural carbonation, and an almost neutral pH.  It also has a unique salinity on the finish. 

 

Archaeological evidence suggests that the area near Caldes de Malavella has had a human population since prehistoric times. The many local sources of effervescent, thermal water were likely a major attraction. Both springs draw from a single aquifer, although each water emerges with a slightly different composition. Vichy Catalan water was first bottled in 1889, and an influx of visitors led to the construction of a spa soon after. Water and carbon dioxide gas are harvested separately from the source, after the water has cooled the gas is added back in.
