The heart of Tenjaku whisky lies within the natural ingredients used to craft it. Nothing is more crucial than the spring water used during the distillation process. All the water is drawn from the Misaka mountain range, 250 meters below ground and is filtered through volcanic rocks to ensure a velvety smooth texture and moderate mineral contents. The moderate mineral contents in the water create a whisky that is smooth and easy to drink with a well-balanced flavour.
