The spring of Krondorf mineral water rises in the heart of the protected nature of the Doupovské mountains from a single source with a limited capacity. That is why we approach it with the utmost care
The water is always fresh. We bottle it by hand to the order of a specific restaurant.
We bottle Krondorf in original luxury bottles with a volume of 1 liter. The design of the packaging refers to the historic 140-year-old bottle.
Each bottle is equipped with the logo of a partner restaurant and a security stamp that guarantees freshness.
15°C
We recommend serving Krondorf mineral water only slightly chilled. The optimal consumption temperature is 15 °C. Its delicious and interesting taste stands out best with it.
"The Krondorf project, the restoration of factory production of mineral water, which is gentle on the source and the surrounding environment, building on centuries-old practices and emphasizing the properties of water, is the most interesting undertaking of recent years."

Character of water
The spring of Krondorf source rises in the contact points of the steep northern slopes of the Doupovské mountains stratovolcano with the narrow and deep Ohře valley. The cause of the massive volcanic activity here, which began 37 million years ago, is the development of the Oher rift and the crossing of two very important deep faults in the earth's crust, the Litoměřice and Jáchymov faults. It is precisely the deep-reaching fault faults, the specific rock environment and also the morphology of the landscape, so different from other places in Bohemia and Moravia, that, with their suitable combination, enable the formation and circulation of this gasified alkaline-earth mineral water, as well as its exit to the surface in a very limited area at the confluence Korunního brook and Ohře. The driving force behind the ascent is both gaseous carbon dioxide originating from the depths of the Earth's mantle and the overpressure of water seeping into the rock environment in the extensive infiltration area of the spring structure.

"The Krondorf project, the restoration of factory production of mineral water, which is gentle on the source and the surrounding environment, building on centuries-old practices and emphasizing the properties of water, is the most interesting undertaking of recent years."
In 2010, exploratory work was started to verify the possibility of capturing highly mineralized and heavily gasified groundwater of a specific composition, which once fed the historic Štěpánka spring. However, it is not easy to obtain a sufficiently abundant source of such unique mineral water. The multi-year hydrogeological survey included a number of stages, including geophysical prospecting, excavation of exploratory wells, logging measurements in boreholes and hydrodynamic testing of both wells. After the completion of a series of sampling and rise tests, one of the wells was definitively equipped as a receiving facility with the name "Krondorf" as a reminiscence of the old name of the entire spring location. After the successful completion of further tests, it was possible to start the process of certifying this well as a source of natural mineral water according to the spa law, and in the next sequence, the process leading to obtaining a permit for the permanent use of the certified source for filling purposes. The use permit was issued by the Ministry of Health of the Czech Republic in 2015. The water from the source "Krondorf" is captured by a well 90 meters deep.
At first, the borehole went through a Quaternary layer of fluvial sediments, then, below, through neovolcanic rocks ejected and ejected during the period of Tertiary volcanic activity, and reached the pre-Primozoic bedrock environment of the Doupovo stratovolcano, which is built here by highly metamorphosed rocks of the type granulites and granulitic gneisses. These rocks were formed by the remelting of older rocks of the earth's crust and upper mantle during the ascent of magma in the area of the Oher rift. In the fault zones of the tectonically affected granulites, highly valued mineral water rich in calcium, magnesium and other important ions and permeated with carbon dioxide circulates. The dynamic reserves of this fractured aquifer are not large; mineral water from the source can therefore be used exclusively for the production of exclusive bottled water, which is very limited in quantity. Krondorf mineral water is deep water with natural carbon dioxide. The estimated age of this water is more than 100 years.
The source "Krondorf" is protected by a two-stage system of protective belts, and it is also protected from possible human intervention by its location on the edge of the almost uninhabited Doupovské mountains with abundant endemic flora and fauna. These mountains have been uninhabited except for their marginal parts since 1953, when a military district was declared here. However, the history of the protection of the Doupovská kyselka dates back to 1881. The influence of man on the quality of the water collected here is almost zero, but the influence of weather and atmospheric precipitation is similarly minimal, as the formation time of the resulting composition of Krondorf water is over a hundred years. However, some chemical components of the water originally belong to the zone of very slow circulation of underground water and are therefore even older. The chemical composition of this unique mineral water is from the first accurate analyzes by prof. W. F. Gintla from 1886 until today highly stable.
The taste of this mineral water is pleasant, fresh and balanced.
"Krondorf" water is a highly mineralized natural mineral water of hydrogeochemical type NaCa(Mg)-HCO3 with total mineralization of 2,350 mg.l-1 and evaporation (at 180 °C) of 1,883 mg.l-1 of salts and insoluble substances. The water from this source has a very high content of silicic acid – up to 142 mg.l-1 in the form of H4SiO4, i.e. practically the highest content of all European bottled mineral waters. The content of free dissolved carbon dioxide in the water of this source is also very high and exceeds the value of 3 g.l-1. It is the above-mentioned depth range of the fractures on which the well of the "Krondorf" source is located that is the cause of the anomalously high mineralization and gasification of its water. -HCO3 with total mineralization of 2,350 mg.l-1 and evaporation (at 180 °C) of 1,883 mg.l-1 of salts and insoluble substances.

In the Czech Republic, Krondorf water is classified as highly mineralized natural mineral water, carbonated, cold, hypotonic, with an increased content of silicic acid. Mineral water is naturally carbonated with carbon dioxide, which - as medical reports remind - helps speed up the movement of digested food through the stomach and intestines, and the water thus appears as a light digestive. It can have a slightly alkalizing effect on the organism.
