In the heart of Macedonia, in the area of Souroti, a carbonated natural mineral water spring has been emerging from the depths of the Greek earth for centuries.
The Souroti spring is officially recognized as a curative spring, and its water is a unique natural resource with distinctive characteristics. Its natural composition is the result of a geological journey that lasts for decades and takes place at depths exceeding 500 metres.
Throughout its long underground journey, the water is protected from external factors and environmental pollutants. As it passes through carbonate rock formations, it is naturally filtered and enriched with valuable minerals.
At greater depths, it becomes naturally enriched with silica (SiO₂) and lithium (Li), elements known for their beneficial properties. The high concentration and simultaneous presence of both silica and lithium make SOUROTI water truly exceptional on an international level.
The Souroti Spring has been systematically monitored since 1916, consistently confirming the exceptional quality of its water and its unique natural composition.
A true gift of nature, worthy of protection.
1. The Formation of the Aquifer
In the wider Souroti area, nature has created a unique hydrogeological system over thousands of years. Within this system lies the aquifer from which SOUROTI natural mineral and curative water originate.
2. From Rain and Snow to the Underground
The journey begins with rainwater and melting snow, which gradually infiltrate the ground through pores, fractures and rock formations, slowly making their way to greater depths.
3. An Underground Journey Lasting Decades
This is not a rapid process. The water may reach depths exceeding 500 metres, while its underground residence and circulation within this unique geological environment are estimated to exceed 50 years.
4. Natural Enrichment with Minerals
During its long underground journey, the water comes into contact with different geological formations. Through this entirely natural process, it becomes enriched with bicarbonates and essential minerals, including calcium, magnesium and potassium.
5. Deeper Physicochemical Conditions
At greater depths, the interaction between the water, the geological formations and the area’s geothermal field creates unique physicochemical conditions. There, the water undergoes further natural enrichment with lithium and silica.
6. Natural Filtration and Upward Movement
As it passes through the rock formations, the water undergoes a natural filtration and purification process, without mixing with surface waters such as rivers or lakes. Its final route is guided by the geological structure of the area, particularly the Anthemountas Fault, which extends for more than 30 kilometres.
7. Emerging at the Spring
The natural presence of carbon dioxide in the water contributes to its upward movement, naturally driving it towards the spring. In this way, the water completes a remarkable journey that began as rain and snow, continued underground for decades and finally emerges at the point of abstraction.
Protecting the curative spring and the natural environment has always been a top priority for SOUROTI. Responsible management of this natural mineral water resource is based on scientific monitoring, sustainable practices and continuous investment in modern infrastructure.
As part of this commitment, systematic hydrogeological and environmental monitoring is carried out in collaboration with specialised scientists and universities, ensuring the responsible management of the natural resource and the long-term sustainability of the spring.
At the same time, the company’s returnable glass bottle system makes a significant contribution to reducing its environmental footprint. More than 20 million green glass bottles are returned every year, thoroughly cleaned to strict standards and reused, significantly reducing raw material consumption and waste generation.
The investment programme launched in 2025 further strengthens this commitment through projects that include energy-saving systems, material recycling and modern waste management infrastructure, contributing to the continuous reduction of the environmental impact of the production process.
SOUROTI also invests in environmental education, supporting Environmental Education programmes in both Primary and Secondary Education, as well as initiatives that promote the sustainable management of natural resources, sustainability and respect for the natural environment.
Since 1991, SOUROTI has welcomed students and teachers from across Greece to its facilities, offering educational programmes and presentations on the environment, natural resources, water and the company’s sustainable management practices.
To date, approximately 2,000 school visits have taken place, involving more than 120,000 students and around 8,000 teachers, helping to foster environmental awareness among younger generations.
Respect for nature is not simply a commitment, it is an integral part of SOUROTI’s identity. Protecting the spring today is the best guarantee that this unique natural resource will continue to exist for generations to come.
Souroti has a rather high natural concentration of carbon dioxide at the source of abstraction, in the range of 1200 mg/L, which is one of the criteria required for recognition as a Natural Mineral Water.
In order to enhance its flavour with a greater sense of carbonation, carbon dioxide of natural origin, extracted from the earth from areas with underground layers of carbon dioxide, is added during the bottling process.
Seeing as there are many references to the term “NITRATES” we would like to point out, for the better information of the public, that Souroti belongs to the category of natural mineral waters with Nitrate levels that are undetectable or lower than 0.4 mg/L.
