ZAGORI water is bottled at the source, at the foot of the mountain range Mitsikeli – at Zagorochoria, with no further treatment, and is provided to consumers through strictly observed procedures and controls, and certified with ISO 9001:2000, HACCP ΕLOT 1416, HACCP Codex. The water table, from which the ZAGORI water is collected – certified by specific hydrogeological studies and analyses – is protected against any external influence and environmental contamination, while its physical structure ensures the unchanged quality. Moreover, the geological formations of the region give the particular water content in minerals and nonmetal elements and shape its balanced flavor, while acting as natural filters exempt the water from the presence of pathogenic microorganisms.

The origin of the water, the virgin region of Zagori, the unsurpassed quality and its particular constitution, characterizes it as:

• Natural Mineral Water of low salt content

The characterization of the water as ”low mineral content” means that it meets the relevant criteria of the EU Directive 80/777 Ε.Ε.: "the mineral salt content, calculated as a fixed residue, is not greater than 500mg/l” and more specifically is 192 mg/l, (namely, not even half of the forecasted). This figure shows that the water is easy digestible, whereas its daily use does not cause any excessive quantities of any element.

• Natural Mineral Water suitable for a low-Sodium diet

The characterization of the water as ”suitable for a low-Sodium diet”, means that it meets the relevant criteria of the EU Directive 80/777 “the sodium content is less than 20 mg/l” and more specifically is 2,69 mg/l. The difference from the maximum level of the criterion, explains why the use of ZAGORI water is recommended in cases where a low-sodium diet is chosen, since sodium, as it is known, is a factor that increases the pressure and the most common mineral to cause fluid retention in the human body.
