Aedan Fermented

Aedan Fermented Japanese koji-based traditional fermented food. We believe that the fermentation process correlates to the human life cycle.

Company Philosophy:

The name Aedan ‘叡伝’ comes from two Kanji characters, ‘叡’ means wisdom, ‘伝’means hand down (as information) from generation to generation. Fermented foods exist closely with nature, and make the best use of nature. These fermented foods fostered in Japan in it’s long history help us realize that humans are also a part of nature. We are passionate to share this ancient, time-hon

ored wisdom to a bright future. Mission statement:
• To provide traditional Japanese fermented foods based on koji, by harnessing powerful micro-organisms, in our hand-crafted way.
• To use the finest local, non-GMO and Certified Organic ingredients available.
• To deliver the unpasteurized beauty of fermentation by koji, enhancing umami of ingredients and increase their optimum nutritional value.
