About 10,000 years ago, at the end of the last Ice Age, glaciers covered Northern Europe, including Finland. As they retreated, they left behind the Salpausselkä Ridge, a geological feature with porous sand and gravel that naturally filters and purifies melted snow and rainwater. This water accumulates in aquifers and becomes the source of Jääde. https://jaadewater.com/about-us/#our-origins
