Here you can buy Koji spores for any kind of Koji you might want to make.
We also have Natto and Tempeh spores and fermented foods (made by us!) such as Miso and Shoyu – all organic. Dried Koji is also available!

Due to the current COVID-19 crisis, we can’t send any orders to: Bulgaria, Estonia, Greece, Israel, Canada, Lithuania, Latvia, Romania, Russia, Hungary and Cyprus.
If you order nonetheless, we will send your order once these restrictions are lifted again, though we don’t know for sure for how long they will be in place. If it is really important to you, we can organize shipping, but it will cost about 20€ for up to 10kg. Please order via email in this case.

We still ship to every other country that we usually ship to.


The Koji starter / koji kin is sourced directly from a reputable producer in Japan. The Tempeh spores are from Indonesia and have been tested for Salmonella and other relevant microbes.

Shipping is free Europe-wide if you order more than one bag.
