The best-known mineral water from Spain, Vichy Catalan has very high mineral content, natural carbonation, and an almost neutral pH.
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.
