Borsec is situated in the Eastern Carpathian Mountains of Transylvania, and is one of the most renowned curative spas in the subalpine, windless, peat-rich county of Harghita, Romania.
It is listed in the country's register of historical monuments. Bottling of Borsec commenced over two hundred years ago, and since modernization in 1992, the facility outputs two million liters per month of its legendary "Regina Apelor Minerale SA Borsec " (Mineral Water Queen Borsec).
The curative properties of the water were already known in the 1600s, and for centuries it was transported by carts in wooden casks to be served in the Royal Court in Vienna. It was Emperor Franz Josef who dubbed Borsecthe "Queen of Mineral Waters."
The pH, although slightly acidic, is near enough to neutral to distinguish Borsec from other naturally carbonated waters whose carbonic acid origin tends to create much lower final pH levels in the harvested water. The Calcium is high at 310 milligrams per liter.
Magnesium and Bicarbonate - are robust at 97 and 1,800 milligrams respectively. However, the Sodium level is very low for a high mineral water at only 53 milligrams per liter. Traditionally, Borsec has been helpful for circulatory disease, anaemia, disease of the endocrine glands, nervous disease, rickets, renal disease, diabetes, and even for obesity.
It's most popular use today is as a super-healthy drinking water.
Borsec was awarded a GOLD medal at 2004 Berkely Springs, WV USA International Water Tasting event, for carbonated waters.
