It was around the 1980s that the exceptional chemical composition of our water, with a very low dry residue, was confirmed, but it wasn’t until the 1990s that it was declared a mineral water.
The architect of this recognition of its qualities was Don Esteban Luengo, one of the members of the family that owned the land where this spring has flowed naturally for centuries. For years and years, Esteban pursued his dream of demonstrating the excellent quality of this spring’s water with determination and tenacity until he realized it.
Using the original name Luengo, in honor of its original promoter, before being marketed, it was called Teleno, a reference to its origin.
