Welcome to the Koji Shop!

Here you can buy Koji spores for any kind of Koji you might want to make.

The spores are sourced directly from a reputable producer in Japan.

Shipping is free Europe-wide if you order more than one bag. When ordering one bag of Koji spores, shipping is 1,50€. Shipping for Tempeh starter is free.

Customers from Italy: so far, of 7 orders, 2 have not arrived at their destination. For this reason I now offer insured postage. This way you can have a tracking number and the certainty that your letter will arrive. If you opt for free shipping, you do so at your own risk.

Customers from the United Kingdom: please know that shipping by letter does take a bit longer than to other countries in the EU.
