Our water
From the spring to your table, Acqua Silva arrives every day with the same purity it has at its source in the mountains. It rises from the Orticaia Spring, almost 1,000 metres above sea level, surrounded by the unspoilt nature of the Tuscan Apennines. Along the way, it is enriched with precious minerals and retains a light, balanced composition ideal for everyday well-being.
