Wiesentaler brand is owned by Wiesentaler Mineralbrunnen GmbH in Germany.

The Wiesental mineral water has a long way to go before it gets into the bottle. The layers of rock that penetrated the water over the centuries are responsible for the taste. The Wiesental mineral water is separated from the groundwater by impermeable layers.
