Welcome to the Koji Shop!

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

I source the spores directly from a reputable producer in Japan.

Shipping is free europe-wide if you order more than one bag. When ordering one bag of spores, shipping is 1,50€. Customers from the UK: please know that shipping by letter does take a bit longer than to other countries in the EU.
