Genesis · Ulleungdo, East Sea
Reserve is drawn from a deep, cold layer of the East Sea around Ulleungdo, isolated from surface mixing. It is bottled in glass as a limited release. Full third party testing is underway, and complete results will be published before general availability.

A limited glass release. Full source testing in progress.
Ulleungdo is a volcanic island that rises from the East Sea off the eastern coast of Korea. Around it, the sea holds a deep, cold layer that sits apart from the surface.
The East Sea behaves like a naturally enclosed basin. Its narrow entrance lets water circulate internally rather than mix freely with the wider ocean, which gives the deep layer its own temperature and character. Reserve is drawn from this layer.

Seawater carries minerals by nature. Water drawn from the deep East Sea layer arrives already mineral bearing, rather than relying on minerals added later. The full mineral profile for the Ulleungdo source will be published once accredited testing is complete.

Most ocean water mixes constantly with the surface, the weather, and the watershed above it. The deep layer of an enclosed basin does not. It stays cold and stable, removed from surface runoff and seasonal change. That stability is what makes a deep source a consistent starting point.
Surface and shallow sources
Mix with the surface. Temperature and chemistry shift with the seasons. Exposed to runoff from the watershed above.
Deep East Sea layer
Sits below the surface mixing zone. Cold and stable year round. Removed from surface runoff and seasonal swings.
