The natural mineral water of Alzola Basque Water, is a thermal water that emerges at a constant temperature of 28 ° C throughout the year, without altering the chemical composition throughout the 170-year history of the spring.

This thermality, is due to the depth reached in the subsoil, around 700 m. 

The water of Alzola Basque Water is unique, it has not changed its composition since data is available. Considered a water treasure, it has an extraordinary quality for our health.

The origin of the water is in the mountains of Izarraitz, where the water seeps into the subsoil and begins a slow journey of between 20 and 25 years, until it emerges naturally in our precious Alzola spring.

The Alzola spring is one of the oldest in Europe, discovered in 1775 and declared of public utility in 1843. It produces a mineral water with a composition recognized by all experts, as excellent, which is also demonstrated, with a hydrochemical diagram that reflects a unique symmetry between anions and cations, which ensures and guarantees its special balance.
