Purest water has been preserved in its original state in the underground deposits around Baikal for millions of years. The mineral base of the deposit is an ancient sea, the age of which exceeds 500 million years, the period known as “lower Cambrian”. These deep natural storages are where BAIKALSEA Company takes their unique low-mineralized mineral water. “Baikal Reserve” water is extracted at the Olkhinsky deposit, from the well number 27-bis at the depth of over 350 meters. At this depth water is protected from any outer influence and has kept its well-balanced natural mineral composition preserved from the time of the first operation of the well.
