Each packet will inoculate up to 200kg/440 lbs of rice, barley, or soybeans.
Since the spores are very small, we suggest mixing the koji spores with rice flour. Mix 424g of rice flour with the spore packet. This will give almost a quart size amount of koji-kin spores. 1g spore/flour mixture for 1 lb (454g) of koji substrate. Once pre-mixed, use as suggested in recipes or for making miso or other Japanese fermented foods. See our recipe section for ideas.
The mixing procedure is very simple…
Step 1: Start by sterilizing the substrate, in this case rice flour. In a large pan or skillet, toast the rice flour until slightly brown. Do not burn the rice flour. Cover and allow the rice to cool to room temperature.
Hint: Place in freezer for faster cooling times.
Step 2: Once cooled, add the rice flour to a sterilized quart size jar/container. Open a corner of the spore packet and add to the jar/container. Caution – Be very careful when handling the spores. They are very light and should not be inhaled.
Step 3: After adding the contents of the spore pack, secure with lid, and gently shake and rotate to mix the rice flour and spores. The mixture should have a uniform green colour. Label and date the mixture and store in the refrigerator/freezer or a cool, dark area. Stored in this manner, the spores will maintain full potency for six months or longer.
